Building a Wooden Deck Over a Concrete One

Google+ Pinterest LinkedIn Tumblr +

The materials ought to be fairly apparent – wooden. And loads of it. When you go purchase your provides, ensure you get a minimum of 10-15% additional of the whole lot, as a result of some beams may have unpleasant knots, won’t be completely straight (even straight ones may warp a bit within the solar if left unused for a number of days), and many others. Same factor applies to screws – get a variety of them.

Protection

This one comes earlier than the rest. I’ve gotten mud in my eyes extra occasions than I care to rely, and have felt my ears ringing greater than as soon as after drilling and chopping. I do not need to cope with that any extra, and need to keep away from any injury. You ought to be very involved with this as effectively, so ensure you use a great pair of goggles that seal the area between the lenses and your pores and skin, in addition to good ear plugs. Do your self a favor and get a pair that may be simply eliminated and put again on (just like the pair within the photograph) even when your arms are soiled, as you will want to do that typically.

Wood  

Depending on the place you reside and what’s obtainable, you will most likely have a alternative between handled yellow pine (the inexperienced stuff) and cedar. The latter is of course water and bug resistant, smells superior and appears nice as-is. The former is three to 4 occasions cheaper. You do the maths.

Treated pine can at all times be stained and painted any colour you want, however ensure you comply with the stain/paint directions rigorously. I am staining our deck, and the directions I discovered have been that you simply mainly can’t apply any stain for a number of months as a result of the chemical compounds injected into the wooden won’t let the stain penetrate too deeply and this implies it will not final lengthy. I’ll let the wooden climate till subsequent summer season, at which level I am going to apply wooden brightener/cleaner to it after which the stain.

You even have the selection of going with composite decking supplies which appear like wooden however are made from rather more climate resistant supplies. These will price you much more than cedar however will final approach longer. Their down aspect, although, is that they actually do not feel like wooden (for my part). You do not get the identical feeling of heat, the slight creaking, the colour, and many others.

Quantities – this one will rely strictly on what design you select for the flooring, the railing and any extras like storage beneath the deck, benches, and many others. I’ve used the commonest sizes of obtainable lumber, although:

2″ x 2″ and 1″ x 2″ – flooring assist, railing balusters

5/four” x 6″ x 10′ – flooring boards, railing prime caps

2″ x 6″ x 10′ – skirts

four” x four” – railing posts

2″ x four” – prime and backside railings

Screws and bolts

There are an entire bunch of screws you need to use on lumber, however you will need to completely guarantee those you get are meant to be used with decking (i.e. climate and [if using treated wood]ACQ resistant). The chemical compounds in handled wooden will work together with non ACQ-approved screws and trigger them to corrode (because of excessive ranges of copper within the preservative), so that you need to keep away from that. 

Sizes – many of the screws I used have been 2″ lengthy, as that might undergo the boards and provide a great quantity of catch onto the bottom beneath them. For the handrails I used 2″ screws (and nails) for the balusters and three” screws to connect the railings to the four” x four” posts.

You’ll additionally want concrete screws (e.g. Tapcon) for attaching the ground helps to the concrete. I used three” screws for this step.

Finally, for the railing posts, you will want zero.5″ x 6″ (for notched posts) and zero.5″ x 7″ bolts (for non notched posts) to connect the railings to the edges of the porch. The concrete in my case is 6″ thick, which is sufficient room to connect to bolts one on prime of the opposite, about 2″ aside. If yours is any thinner I would counsel searching for options.

Nails  

I used four” nails to connect the balusters to the railings (together with the two” screws). Same guidelines applies as for the screws – get ACQ accredited (maybe even galvanized would work)  nails.

Glue

I used a good quantity of development adhesive for locations like the ground assist, the skirts and the balusters, so you will want a number of tubes of it. I additionally used carpenters glue when gluing the helps for the benches, however might have used the development adhesive there as effectively. 

Silicone

Anywhere the water has an opportunity of accumulating close to wooden ought to get additional consideration, and the primary place this occurs is on the concrete subsequent to the runners. The wooden is already handled towards water, however since these locations will likely be inaccessible sooner or later you need to do as a lot as doable now to forestall water injury afterward.

 

Wood sealer

Treated wooden is mainly wooden into which a preservative liquid has been inserted by utilizing a vacuum and many stress. It’s essential to notice, although, that this preservative doesn’t make all of it the best way to the core of the lumber, and solely infuses the primary inch or so on all sids. This is simply high quality when you’ll be utilizing the lumber as-is, however you will not. You’ll be making a ton of cuts to suit the wooden into totally different shapes and sizes, and will likely be exposing the untreated innards to the weather. To shield these areas towards moisture and bugs you will must deal with them with a wooden sealer, which is mainly a liquid that smells a bit like paint thinner. It is clear and doesn’t go away a hint (you will see it for the primary couple of days however nothing afterwards), and might simply be brushed on to the freshly minimize ends. Keep these items close by as you will be utilizing it typically.

Tools

 I most definitely do not envy individuals who needed to construct stuff earlier than the appearance of energy instruments. Even with the next ones you will nonetheless want a little bit of energy for among the steps. 

A daily drill and a hammer drill – You’ll be needing two drills all through the entire course of as a result of the overwhelming majority of the holes should pre-drilled earlier than placing screws in them. You’ll even be needing a hammer drill for the sections the place screwing into the concrete are involved, so I had an everyday drill with a screw head on it, and the hammer drill with both the masonry bit or wooden bit on it relying on what step I used to be on. You do not want the drill to hammer when drilling pilot holes in wooden, so a hammer drill that may flip the hammering motion off is preferable.

Saws – you will want an everyday handsaw (for ending cuts), round noticed, miter noticed and a reciprocating noticed. The final one is optionally available, although. I believed it will be a assist in trimming the posts to their closing peak however might have simply performed it with a round and hand noticed.

Usual toolbox of stuff – hammer, screwdrivers, stage, chisel, and many others.

You’ll additionally want wooden drill bits, as all screws ought to be going into pilot holes as a substitute of into uncooked wooden. Using pilot holes on the whole lot will definitely take you longer, however will keep away from cracking and cut back the stress on the wooden serving to it last more.
