Doing an Amtico job just now 6mm ply down, feathered, planks laid and looked across it in the natural light and it looks like flow lines between mixes of screed in a couple of places if you get what I mean, nothing major but the likes of us would notice it, never seen this before any suggestions? Guy I was working with says he gets that with every ply job
you will normally see ply through the floor try sanding the board joins with small sander before feather finish that helps but best is to latex with a flex but customers dont normaly like paying for ply and screed
I've found that if you run your hand over the 6mm sheets it's full of dips or low spots? That's another good thing about jumpax, the boards are machined absolutely perfect, the joins don't even need feathering
the ply is prob diff heights if one side of join is even 1/4 mm diff than other side it will show through
If you don't ask for far eastern they will usually give you chinese as this gives them more profit on each sheet...
Since I started using the Brazilian ply form Travis Perkins no issues. On my mates house I used 700 on the joints tight, then feathered the whole floor. Been down since summer and no lines showing
Thats what i think the ply has different heights/high spots low spots because the areas in question are nto where the joins in the boards are.
It's hard to believe but there is such a difference between 6mm and 9mm (and not just 3mm before someone says it)
there is also the issue that plywood and wooden subfloors contain moisture also. Most on here are now understanding that we test concrete for moisture to make sure its below 75% RH. Well wooden subfloors should also be tested on a MC scale. If its not correct then plywood will be effected just like a wet concrete subfloor can effect products. There is a lot less chance that wooden subfloors will have a issue but we still see loads of problems. The better the quality of plywood the more chance the plywood will mask the moisture issues. .......Worms..... Can.......... And to think that our trade is not classed as a 'craftsmans' trade. Some chap driving a forklift truck is regarded as having a more qualified / professional trade.
