H F Posted August 21, 2019 Share Posted August 21, 2019 We commissioned a guy to build us a shed in our garden. The wood has obviously expanded, but it seems to have expanded an awful lot. I think he said that he made a biscuit joint to keep the wood together in the doors to prevent this kind of thing from happening. The gaps are now about 1cm wide. I was thinking of buy 5cm wide slats and placing them over the gaps because the shed's not watertight now and we keep our outdoor cushions in there. Is that a good idea?

RichS Posted August 21, 2019 Share Posted August 21, 2019 The timber has shrunk (not expanded) as it has dried out in the sun, a not uncommon problem nowadays, even with merchant bought gates. Pity he didn't form a full length tongue instead of biscuits. Won't do any harm to cover over the gaps with something like tile lath and just stain in to match. Best to only put fixings into one side of the lath and then it will still allow movement as necessary. 1 1 Link to comment Share on other sites More sharing options...
Cpd Posted August 21, 2019 Share Posted August 21, 2019 I would use a 50mm wide batten to cover the gaps all the way down and some stainless steel screws. Photo of what it would look like. 2 Link to comment Share on other sites More sharing options...

We use galvanised, rust proof screws that we've used on our log store and they've been awesome. Link to comment Share on other sites More sharing options...
scottishjohn Posted August 21, 2019 Share Posted August 21, 2019 (edited) modern wood is so unseasoned its nearly still growing -- to be fair it was probably the cheapest stuff he could find + not even treated or it would not be showing so light a colour-- its just crap these days really pisses me off half the so called treated wood when cut it you can the "treatment" only goes in about 3mm and it was probably wet when done --so that has been dipped not proper pressure treated which would force it right through small section wood like that --bean counters again saving on the cost of treatment fluid and when the moisture drys out of center --it shinks proper treated timber should dimensionally stable when you get it last proper treated timber i got was 100mm square decking post --it was treated all the way through ,which i used to make a summer room frame Edited August 21, 2019 by scottishjohn Link to comment Share on other sites More sharing options...

We'll seal it with battens and apply another coat of protection. The work never ends. Link to comment Share on other sites More sharing options...

The work never ends. if good tiles batons you should see the treatment all the way through when you cut them and i hope you not using one of the water based preservatives --they don,t last any time at all . eg --do you wash your brush out in water ? they are really paint not a preservative-no matter what it says on the tin good old Eu and EPA --have stopped us using most of the real old fashioned types which worked old engine oil was the favorite round here with gardeners -no cost and last a long time and acts ass weed + bug killer where it drops off under the fence LOL Edited August 21, 2019 by scottishjohn Link to comment Share on other sites More sharing options...

Onoff Posted August 21, 2019 Share Posted August 21, 2019 Bottom line is the guy who did it was a bit inexperienced. Should have done a continuous tongue and groove like I did on my gate using 6mm marine ply. Glued one side only. Been like this 5 years and perfect. The boards can expand and contract as they like and no gaps. Thinking about your situation then your boards I junk might still expand / contract. If your 50mm strip is affixed over the gap but to both boards I wonder if, over time the strips will split? I might be tempted to fit 70m strips but to one side of the gap only. Then it can slide over the adjacent board to allow for movement. Only worry there is will the boards, affixed one side, "curl"? How about, as a cheap "try": Buy a few tubes of the cheapest black silicone and put that in the gaps finishing with a decent Fugee tool. Link to comment Share on other sites More sharing options...
Onoff Posted August 21, 2019 Share Posted August 21, 2019 I used black Cuprinol on the edges and ends (by standing in a bucket so the end grain sucked it up). Then 3 coats of black satin Bedec barn paint on the rest of the wood. It's superb stuff (and reassuringly expensive). New Zealand Deck Stain gets good reports too: Link to comment Share on other sites More sharing options...
Cpd Posted August 21, 2019 Share Posted August 21, 2019 As @Onoff says it’s a pretty poor job.... but it is what it is. I agree about the batons potentially causing some problems but I would not use 70mm only fixed on one side as I think they will lift and look messy, better to fix the 50mm ones through the middle so the fixings go through the gap in the boards as shown in my photo above. You could easily put something on the back of the door to run the screws into. This way the wood can expand and contract without splitting. But again all this is because it has not been done correctly. I have build various doors and the one in the photo below was with unseasoned larch but I put in a big larch Tongue expecting them to shrink and they have been up for six years without fault.

Temp Posted August 21, 2019 Share Posted August 21, 2019 I had an oak "shed" door made and they used T&G boards. These expanded and having nowhere to go the whole door bowed until it looked pregnant. If T&G is used it shouldn't be fully seated. I had to run a saw down the joints to allow some movement. Link to comment Share on other sites More sharing options...

Like mini I beams at each gap. The inner ones would I guess need cutting to suit if the door is ledged and braced. Think I'd still fill the gaps with something soft.

H F Posted August 22, 2019 Author Share Posted August 22, 2019 Thanks cpd and onoff - I’ll do as you and screw through the back into a cross beam to allow movement. This has all been very eye opening. Link to comment Share on other sites More sharing options...

I don’t glue in the tongue, it’s just a perfect fit, as the boards are wet they are only going to shrink not expand and the floating tongue allows for continued movement. But your right in that if the boards were dry they would expand and warp as they would have nowhere to go ! always something throwing to trip us up on a self build.......

joe90 Posted September 17, 2019 Share Posted September 17, 2019 My personal door to my garage is tongue and groove, not cheap and because its painted and faces south the joins crack the paint every year, i caulked it and repainted but yep the cracks in the paint come back. Can’t stop wood moving I suppose. Link to comment Share on other sites More sharing options...
