How To Install Picture Frame Trex Composite Decking on Concrete Slab / Backyard Makeover / DIY

In this video, I built my first composite decking using Trex composite boards. You can find the material list, hardware needed and tools I used below. I spent nearly $1700 on the hardware and material. If you have any questions please leave a comment below.

Update: Dear all, after making the frame I waited about 2 weeks to watch the drainage, I didn’t see any problems even during heavy rain because the surface of the concrete slab is not even. It has also a very rough surface that allows water flow. Thank you

Hardware and Materials Needed

It comes with 4 starter clips, so if you buy 3 boxes you will have 12 starter clips that will be enough for most of the projects. You don't need to buy additional starter clips.

5. Trex Enhance Basics 8-ft Saddle Square Composite Deck Board. I used 8 of them. $14.80 each

6. Trex Enhance Basics 12-ft Saddle Grooved Composite Deck Board. I used about 43 of them. $22.20 each.

7. Sakrete Crack Filler Gray Concrete Polyurethane Repair (32-fl oz) $10.28

8. Severe Weather 2-in x 6-in x 16-ft #2 Prime Pressure Treated Lumber ( I used 8 of them). I ripped them to make 16 2 X 3 X 16 boards.

Dear all, after building the frame I waited about 2 weeks to watch the drainage, I didn’t see any problems even during heavy rain because the surface of the concrete slab is not even. It has also a very rough surface that allows water flow. Additionally I used some spacers that doesn’t included in the video. Finally, this is a DIY video and it was my first decking experience. Yes I made a lo of mistake but I would not be able learn the best way without trying. Thank you 🙏

Being an old gal who has more time than money, I’ve become dependent on these videos. I’ve replaced my garbage disposal, tiled kitchen backsplash, tiled shower, installed crown molding throughout my house and repaired my lawnmower, just to name a few. Decking over my old concretely back porch is next, and this is how I intend to do it.

Sitting the full length of the board in the ground is not good. Even if it’s sitting on concrete.. water can pool and rot the wood, even if it’s pressure treated..

If anyone is planning to build a deck like this using Trex, please make sure to place your floor joists closer together, say 12 inches, instead of 16 inches as these boards have lots of give to them and you'll soon see a sag forming between the joists. I learned the hard way.

I am a carpenter n finish carpenter, he did a very good job.Ive worked with that decking several times n I would have to say he did a perfect job.they sell little matching plugs for the screw holes.

[marccourt]

The finished deck looks awesome. Thanks for the video.

Nice job sir, especially for your first deck. Repetition is the mother and father of all learning! I see some harsh comments but I don’t see them doing projects on YouTube! Keep doing what your doing!

[nonniesview]

This is a beautiful deck, love the way it came out.

[WindoWarrior]

I've been trying to figure out things myself YouTube is absolutely invaluable. I imagine going all out for this 30ft, er RV or something simple enclosed on the side. I would like to use as much recycled materials as I can. From large metal can concrete peirs too plastic bottle trash bricks pinned in with chicken wire finished with recycled foam and concrete mix. Probably just a tin roof or just a plastic tar tile floor instead of wood framed floor or trex then yeah.

Nice deck but it appears that drainage may be a problem. Treated lumber rots too especially if subject to water immersion. Actually the treatment does not penetrate the wood completely so ripping the boards would expose untreated wood too. Preserative should be applied to the ripped edges.

One of the other fix it guys suggested securing each end of the boards first then pushing the centers of the boards and clipping. Seemed easier. Nice result

I love watching people build things wrong, because that’s exactly how I plan to build. If it can be done that’s all I need to know!

[jimserhant]

The deck came out absolutely beautiful. Thank you for sharing the process with us. The ONLY thing I would’ve done different was used cortex screws for the edge boards. It would’ve saved you time in pre drilling and it has plugs that match the saddle decking to cover the holes.

[ricktweden]

I used the exact same decking from Lowes. Since you opted not to use the expensive screw and plug system for face-nailing, you may be able to try the colored wax crayons that are available for covering nail holes and scratches on stained wood. You can find them in the wood filler section in the paint dept. They also make color putty in small jars that works well. You can blend the various colors together to get the exact shade desired. Not sure if it will hold up to the heat outside, but you have nothing to lose by trying it.

For the first-timer, God bless, excellent job.

[alionar]

We want to build your deck's same in my neighbor's backyard. I checked your descriptions. Those are perfect. You explained every tool and you shared their link. Thanks again.

my advice to anyone thinking of doing similar, make sure to raise it of the ground a bit, for water drainage.

[van]

Very nice job. I'll be following your plan when i get ready to do mine.

[michaelmika]

This looks great. I wish I was 20 again... Thank you for a great video.
