Got some treads and risers to do on a couple of flights of new chipboard stairs in a shop in heavy duty vinyl. Nosings being fitted after treads and risers are stuck. Would you guys: a/ prime chipboard b/ skim chipboard c/ ply chipboard d/ prime and skim chipboard e/ glue with f44 f/ glue with contact g/ glue direct to chipboard While I realise that ply would be the ideal choice, to ply all treads and risers will add a huge time factor that we haven't costed in, and seems to be overkill.
I would want a guarantee from the adhesive manufacturer that the adhesive will work on chipboard. Uzin do some interesting adhesives for stairs. Might be worth a look into Sent from my iPhone using Tapatalk
F.Ball say: STYCCOBOND F44 can be applied to STOPGAP smoothing underlayments, structurally sound, smooth, dry subfloors of concrete and sand/cement screed, plywood, flooring grade chipboard and hardboard. My concern is if I will get enough grab on the risers to stop the vinyl curling or falling off. And would contact adhesive migrate through and turn a beige coloured vinyl yellow (plasticiser migration)?
I'd ply them but if you really don't want to then If they are nice and flat (smooth) I'd prime, let it dry off completely then f44 them on. Some will disagree no doubt but heyyyy hooooo... ....If it's XL you fitting then I wouldnt bother and I'd turn my phone off!!
Should over plyd If Your lucky and all the stairs are all of a simlar size you can make one or two temples and cut the lot in one go with a plunge saw and rail cutting multiple sheets at once. Some new chip boards are produced in a different way and you can actually stick directly to them but you need to check the spec. If it’s the traditional green type it will stick initially but could fail over time
This guy, I hope I never have to take up a floor you’ve laid. Hate it when stairs have been put on with contact adhesive. Pull the stairs apart when you have to remove it! I know I know it’s not your problem lol Sent from my iPhone using Tapatalk
I’d always overply, I never trust chipboard seen a fair few failures before even when everything was done properly except plying out. Sent from my iPhone using Tapatalk
I`m lol, we have been doing the gym floors for about 8 years now, and they have awarded us a lot of refit work. This will be on a rolling 5 year contract, so we are having to take up a fair bit of stuff we fitted before. I`d still use F61.....
