Safety First


When handling and processing treated timber always wear gloves and eye protection and work in a well ventilated area.

Wash hands thoroughly after handling treated timber and especially before eating or smoking.

Do not burn timber off-cuts. Dispose of them safely as refuse. Treated timber contains chemical preservatives.

When constructing pergolas keep the surrounding area clear of people until the structure is fully secure.

Wear goggles when pressure washing or scrubbing with chemical cleaners or restorers.

Keep children away from the work area until the job has been completed and tools have been stored safely.

A Treated Timber User Guide for TANALISED® E /TANALISED® EXTRA treated timber covering its general use is available from Lonza Wood Protection - www.lonzawood.com.

The grinding and cutting of Q-Grip® products may produce dust and loose flying particles and we strongly recommend that personnel carrying out these tasks wear suitable Personal Protective Equipment including gloves, eye protection, particulate dust mask and ear defenders.

All Q-Deck® products should be fixed or secured using recognised quality products. We recommend the use of screws to fix deck boards and bolts or structural screws to secure newel posts or structural elements of the deck. The raw material and the type of coating used to protect these from corrosion is vital.
This is why Hoppings recommend stainless steel fixings for the best results.
If galvanised fixings are used they should be of the hot dipped variety to help avoid corrosion. We do not recommend the use of pneumatic nail guns to secure decking boards.
Q-Deck®-Tite Plus Stainless Steel Decking Screws are available for use with any Q-Deck® decking but especially Lyptus and our new Q-Deck® smooth Garapa decking.
Q-Deck® Lunawood decking features a special concealed fixing clips and stainless steel screws. 100 per box (includes driver bit).
On 500mm joist centres 17 clips are required to fit one square metre of 26 x 117mm Q-Deck® Lunawood hidden fix decking boards.
Always follow the manufacturer's instructions when working with deck fixings.

Top Tips & Guidance

  • It is advisable to loosely lay components, ie. in particular deck boards, out on the finished sub frame prior to securing them. The longer they are left to become surface dry the less the effects of shrinkage will be apparent after fixing them. The timber can also be cut and sanded more easily when dry.
  • Fix boards with corrosion resistant screws, or for the very best results use stainless steel screws (2 screws 15-20% of its width in from each edge of the board). Structural fixtures and fittings should be specially coated or of hot dipped galvanised material.
  • It is advisable to pre-drill pilot holes near the end of boards to avoid splitting.
  • Deck board screw length should be 21/2 times the thickness of the deck board.

  • For maximising its life it is advisable to cover fabric weed membrane with pea shingle.
  • It is advisable to loosely lay components, ie. in particular deck boards, out on the finished sub frame prior to securing them. The longer they are left to become surface dry the less the effects of shrinkage will be apparent after fixing them. The timber can also be cut and sanded more easily when dry. Note: If the boards are allowed to fully dry out prior to fitting, the gap between boards should be increased to 9mm to allow subsequent expansion in the wetter seasons.

  • All cut ends and notches made to the timber components must be protected with a suitable brush-on end grain preservative (eg. Ensele®/ Ronseal® end grain preserver/Hickson Decor® end grain preservative) to maintain the integrity of the preservative treatment. Where possible Use Class 4 components should not be cut, notched or bored if they are then to be used in ground contact. If Use Class 4 deck support posts are cut then the cut end should not be placed in the ground. If Use Class 4 deck joists for ground level or partially elevated decks are cut then they should be laid on a free draining area of compacted hardcore (or similar) not straight onto earth or areas of lawn. Subframes that are laid in direct contact with earth are at increased risk of fungal decay and subsistence.

  • Cut the top of the support post at an angle to aid water 'run off'.
  • If you need to attach a ledger board to the wall of a dwelling it is advisable to leave a gap between them - use 10mm thick spacer/ packer. This will maintain ventilation and enable the wall and ledger to dry.

  • When using Q-Deck® Lyptus, Garapa or Twinson decking it is advisable to use Q-Deck® Use Class 4 subframe components.
  • For Q-Deck® Lunawood the use of these specific components are a condition of the Q-Deck® Lunawood warranty.

All the guidance above regarding protection and adequate drainage further minimise the risk of fungal decay and insect attack and thus simplify a warranty claim


Technical Advice

INCOMPATIBILITY ISSUES

Take care not to allow uncoated iron products or parts of originally coated iron products to come in contact with Q-Deck®/ Q-Grip® /Q-Deck® hardwood components. Ferrous substances may react with the preservative treatment within the timber and cause unsightly black staining of the surfaces, that may prove difficult to remove. So in particular, it is worth considering if the filing or grinding of metal products needs to be performed near to or over the deck. If possible avoid doing this near decks but if this is not practical then the deck surfaces should be carefully protected/covered to enable capture and disposal of the iron particles. In very hot weather pine resin can rise to the surface of Q-Deck® products and dark stains/coatings can exacerbate this. In the unlikely event this occurs, wait for the resin to form a crust and scrape away; repeat if necessary.


Building Your Deck

PREPARING THE OVERSITE

The oversite must be free draining or of a gradient of 1 in 40 to allow water "run off". If the area you have chosen is grass you can either remove the turf or cover it with a weed barrier, as long as its edges are tucked deep into the soil using an edging spade. If your deck is to be at ground level then the removal of 100mm of soil is recommended. Replace the topsoil with 100mm of compacted gravel or hardcore. This provides a very solid but free draining oversite on to which you can build the sub-frame. On any over site it is essential that you lay a weed barrier. It is advisable to cover the top of the weed barrier with a light stopping layer of pea shingle. You could use strategically positioned patio slabs instead of compacted gravel or hardcore, but we do not recommended this as they tend to settle/subside causing problems with your deck later.


SIZE ISSUES

Wood swells when it is pressure pre-treated with a waterbased preservative - as much as 4% of the finished size after machining - and shrinks as it dries which may vary from piece to piece. This can be evident when butting deck boards end to end. We therefore advise letting the deck boards, in particular, dry somewhat before fitting. This not only helps to achieve a more constant size but improves their workability. Although minimised by the water repellent additive used with Q-Deck® products, climatic changes cause the wood to continually shrink and swell in service and in turn this movement may vary from piece to piece.


SUBFRAME
Aims

  • Structurally sound for its intended end use
  • Only Use Class 4 treated wood should be used in ground contact.
  • Provide lateral rigidity.
  • That the deck will not settle/subside and has a gradient fall in one direction without any low points (sag).

Support Posts and Beams

PLEASE NOTE: For a free draining deck surface, you must incorporate a gradient in one direction of your deck. Most decks (other than ground level) utilise a post and beam construction. The support posts (normally placed at no more than 1800mm) centres sit in or on a concrete footing, the later utilising a metal connector / shoe.

Q-Deck® PLUS Multi-purpose deck posts material is ideal for use as support posts and is also available shaped (3m long classic post), should you want to incorporate a shaped newel above deck level.

Beams are the main horizontal support members of the deck and when connected as pairs (as recommended) can provide both great strength and an ideal place for housing Q-Deck® PLUS newel posts, should you require balustrades. A pair of timbers are either bolted (recommended) or screwed (with, for example, Q-Deck Plus timbertite heavy duty landscaping screws) to the support posts at a height to suit whilst also very easily incorporating a desired gradient for water run off (1:80).

BEAM SPAN GUIDANCE

We recommend beams are constructed from two 44 x 145mm Q-Deck® joists and are placed at maximum centres of 1.8m. In this instance a maximum span between deck posts of 2.0m is recommended.


FIXING THE JOISTS

PLEASE NOTE: For free draining deckboards it is highly recommended that you lay them down a gradient fall. This is especially important if the deckboards are grooved.

Depending on the type of deck you are building the joists can be fixed in a number of different ways.

For a ground level deck or partially elevated you can simply construct a raft which sits onto your free draining oversite.

Fixing joists to beams

Fixing joists to beams

When beams are used in deck construction there are two methods of fixing joists. Firstly if height is an issue you can fix joists to beams using metal connectors commonly known as mini joist hangers.

Alternatively the easiest and most structurally sound way (if height is not an issue) is to simply sit the joist on top of the beams.

It is advisable to nail each joist to each beam at an angle. The tail ends of the joists are secured using a rim joist that is double nailed to the ends of the joists.

With all these joist configurations it is essential that noggins are also fitted between the joists. (Short pieces of wood fitted perpendicular to adjacent joists) These add rigidity to the sub-frame.

If balustrading is required, newel posts must be fitted at this point, before any decking is laid.


Decking Beam Span

Fitting Newels

If balustrading is planned, fit your newel posts before laying decking.

Note: At this point the type of balustrade system chosen will govern the required newel height above the deck.

Double beam construction using Q-Deck® Plus Multi-purpose posts provides the ideal newel post housing.

Secure using suitable bolts or landscape screws in 2 or 3 directions for best results.

Fitting Q-Deck® Treated Deckboards

Laying in patterns or at a 45° angle efficiently utilises any length purchased. It is a good idea to overlap the subframe and cut to desired length in a straight line or curve, if required. If deck boards need to be joined, butt them end to end but take care to stagger the joints so they do not overlap from row to row.

Adding Slip Resistance to Q-Deck® Decking

New Q-Grip® Strip can be retro-fitted to existing decks where the deckboards have become slippery or to certain specific Q-Deck® deckboards, ie. York and Canterbury Q-Deck® deckboards and Q-Deck® Lunawood Hidden Fix deckboards.

Note: To be able to effectively secure Q-Grip® Strip it must be dry and of a temperature above 5°C. Ideally store at room temperature until just before fitting.

To fit the strips to the Q-Deck® deckboards detailed above:

Firstly ensure the grooves are clean, dry free of debris and that any original deck screws used to secure the deckboards in the first place are not sitting proud of the base of the groove. If so, tighten accordingly.

Then consider the area to be covered with Q-Grip® Strips and cut them to length as required using a grinder with stone cutting disc. It is best to place the Q-Grip® Strip flat side down on some scrap wood to do this.

Apply one continuous (centrally located in the groove to be filled) 4-6mm maximum bead of a suitable gap filling adhesive that also has the properties of an external use sealant i.e. flexible and both water and U.V. resistant. You may consider the use of a sealant/adhesive called 'theWORKS' by Geocel® in grey or Sikaflex EBT or 11FC+ by Sika Ltd in grey. Always follow the adhesive manufacturers instructions. For up to date information please download our Q-Grip® literature via the Guides page.

Check for any surface contaminants on the reverse of each Q-Grip® Strip then carefully place the Q-Grip® Strip in the desired position and gently apply downward pressure to 'pinch' it into place along its length using a rubber headed mallet. This action will force the adhesive to fill the voids between the edges of the groove and the back of the specially profiled Q-Grip® Strip.

If you need to butt Q-Grip® Strip end to end then apply slightly more adhesive at this position and carefully wipe away excess adhesive that forces up between the joint sealing the gap in the process.

If an end of a Q-Grip® Strip doesn't 'pinch' sufficiently to allow it to be secured flush with the top of the groove, it is advisable to gently and temporarily secure it with a 4mm gauge 12-25mm long screw. You will need to pre-drill a pilot hole though the Q-Grip® Stripusing a small diameter masonry drill bit (we advise no greater than 3mm). Once the adhesive has cured and created a suitable bond remove the screw and carefully fill and seal the hole it accommodated with more adhesive/sealant

To fit the strips to an existing deck the same process applies as detailed in points 1-3 (if applicable), after you have created your own 5 x 8mm grooves using a hand held router.

N

On hardwood decks this grooving process will not affect any existing warranties that may be in place but we advise that you confirm this with the original supplier. When grooving existing softwood decks it is likely that any existing warranties that may be in place will be invalidated and we advise that you confirm this with the original supplier. This is the case for any Q-Deck® decking not designed to accept Q-Grip® Strip.

Fitting Q-Deck® Lunawood Hidden Fix Decking

The general principles as detailed in the Q-Deck® deck planning and design guide also apply to Q-Deck® Lunawood decking. The hidden fix profile decking allows you to use the quick and easy to use Q-Deck® Lunawood concealed clips and provides a fixing free look. Alternatively you can use two 4.5 x 50mm Q-Deck®-Tite Plus stainless steel deck screws at each joist junction in the grooves provided but pre-drilling pilot holes is recommended to avoid splitting the boards.

1

Fit 26 x 117mm Q-Deck® Lunawood over joists set at 500mm centres, maximum. For commercial applications, in principle reduce to 300mm centres.

2

Leave 6mm gaps between adjacent boards when fitting either Q-Deck® Lunawood with deck screws.

3

When using the concealed clips the lead edge of the first board should be fixed using one stainless deck screw at every joist junction through the groove provided.

Cut the next board to the required length and then carefully butt it up against the first line of concealed clips. Align the board in its length and then fit a second line of clips at every joist junction. You will find that minimal pressure is required to locate each board as the clips pinch them into place as the screw is tightened into the clip. Again take care not to over-tighten each screw.
Continue the process for all subsequent boards until you reach the last one that it fitted as the first detailed above.

It is not a requirement of the Q-Deck® Lunawood 20 year Warranty but highly recommended, is the use of a non-film forming penetrative protective coating.
Also note:
New thermowood products cannot be effectively coated without first opening the pores of the wood, by either applying special chemicals,or naturally, by leaving it to weather outdoors in situation for at least 12 months. The use of Prepdeck followed by Net Trol by Owatrol on new thermowood products or the use of just Net Trol on suitably weathered thermowood products enables the effective application of either Aquadecks or Protext by Owatrol. These non-film forming penetrative systems help protect against the greying effects of U.V. light whilst preserving the appearance of the wood. These systems when used correctly should create a finish. The darker the colour the more the natural appearance of the wood is obscured.

Fitting Q-Deck® Lyptus/Garapa Hardwood Deckboards

1

Fit Q-Deck® Lyptus over 400mm joists centres, maximum

2

Fit Q-Deck® Garapa over joists set at 600mm centres, maximum.

3

Leave 8mm gaps between adjacent boards when fitting either Q-Deck® Lyptus or Q-Deck® Garapa. Being a kiln dried hardwoods means you have to allow for some expansion of the boards during wetter times of the year.

4

It is important to pre-drill pilot holes and countersink before fitting screws to reduce the chance of splitting these timbers, especially near the ends of boards

5

Use a minimum of two 50mm stainless steel screws per board at every joist junction. Use 4.5 x 50mm Q-Deck® -Tite Plus Stainless Steel Decking Screws.

N

Like all hardwood decking Q-Deck Lyptus and Q-Deck Garapa weather to grey after exposure to U.V light. Both are also highly susceptible to staining in contact with iron due to the high levels of tannin present, so it is advisable to only use stainless steel fixings. The black staining that can occur is easily removed using Net Trol by Owatrol.

Over time the tannin can be washed out of Q-Deck® Lyptus and Q-Deck® Garapa. Please note that the fabric of a building or associated landscaping products could become stained by mobile tannin. This washing effect is more likely to occur during prolonged heavy rain and be most concentrated in the period just after fitting your Q-Deck® Hardwood deck. To minimise tannin bleed, new hardwood decking can be coated with Owatrol's Stoptan product. Q-Deck® Garapa deckboards are not as straight as other deckboards in the Q-Deck® range; however any distortion is normally easily corrected when fitting them by applying pressure to bring them back into line.

Creating a Border

Creating a border around the edge of the deck and incorporating fascia boards provides an attractive finish.
The smooth face of Q-Deck® Cambridge decking or Multi-purpose material is particularly good for use as fascias.
Consider using Q-Grip® slip resistant decking or Q-Grip® Strips™ in conjunction with Q-Deck® York/Canterbury/Lunawood Hidden Fix boards to give a border/lead edge with enhanced grip characteristics.

READY MADE SECTIONS

Q-Deck® Plus makes balustrading easy by offering ready-made 1800mm long sections of balustrade, complete with handrail.
All you have to do is fit the sections between correctly pre-spaced newel or pergola posts and screw them into position using Q-Deck-Tite handrail bracket kits. Sections can also be cut to fit narrower gaps between newel posts.

Q-Deck-Tite handrail bracket.
PLEASE NOTE: No opening is permitted greater than 100mm. Therefore, spindles need to be spaced at approximate 120mm centres. Allow 8 spindles every metre of handrail. For decks more than 600mm above ground level it is necessary to achieve a balustrade height of at least 1100mm.
NB: There is a 10mm height difference between the ready-made balustrade and the loose component built version.

FITTING BALUSTRADES USING DECKORATORS BAROQUE BALUSTERS

Deckorators baroque balusters are fitted in a similar way to classic and colonial balusters The construction differs in only 2 ways. Firstly the balusters are fitted to the outer face of the top and bottom Q-Deck® Multi-purpose 44 x 95mm baluster rail. Secondly the balustrade is always capped with a wide flat handrail.

1

Measure distance between newels, cut and fit 44 x 95mm baluster rails to the newels approximately 640mm apart allowing for the top of the baluster to be positioned flush with the top rail and short of the lower edge of the bottom rail by approximately 10mm. (Bottom rail should be no more than 100mm above the deck surface).
