Question

Paint that won't DRY!!!!!!!!!!!


Hi

We are new members and are currently painting a room in our house. Wallpaper was stripped originally and the room has been filled and sanded due to hairline cracks. Before putting on the first coat we sealed the walls with diluted Super Evo Bond PVA

Anyway we have now put 1st coat on the walls and in some parts the paint is not drying, in fact it is still very wet, after 2 hours 90% of the room is dry. Mainly in one corner the wall is still wet. Any tips or help would be very much appreciated.

L&R W

LauraW, If it's mold of some sort, the wall itself will always be damp. Back in NYC, we had plaster walls and it was not uncommon for this to happen. Plaster, drywall, wood are "food" for the mold.

Don't panic just because the paint is still wet in the corners, or any where else for that matter, in only two hours. This is even more so when painting over what is basically an impervious wall (The old primed plaster) , so the only drying that can happen is through evaporation on the open room side, nothing can soak into the wall. Two things you read on paint cans that should never be believed....DRY in 30 minutes, and one coat coverage.

Great many thanks, we have used a dehumidifier in the room and this has dried out the walls thankfully

...didn't see the "2 hours" part

That would be normal
Most paints should dry to the touch overnight

I'm sure now your problem has been solved but in the future the only time you need PVA sealer is for new sheet rock. you can sometimes use just a regular can of flat or eggshell paint how ever it does not adhear to patches as well. It really depends on what type of climate you live in when you paint and what kind of paint you use how thick you apply itr as well as times you should paint believe it or not. Moist and cold areas us a heater with a blower to move the air. Semi gloss paint takes longer when repainting for the simple fact that the paint has no where to absorb the moisture.
painting books can be very helpful
