Tile Master PrimePlus Flexible Primer Peeling Off Plaster

[chrisb1357]

Hi all,

I applied Tile Master PrimePlus Flexible Primer around my bath and sink and for some reason it peels off very easy and has not soaked into the plaster skim so I did not start to tile as I thought it would pull right off with the weight of them if I had carried on.

The plaster skim was done over 2 months ago so its had plenty of time to dry. The area where I applied it was clean and dust free and I followed the following from the tile master site on how to mix.

New plaster must be allowed to dry for a minimum of 4 weeks.
Make sure surface is free of loose dirt or dust. Prime the surface with Primeplusdiluted 3 parts water to 1 part Primeplus, followed by a second neat coat.

I have now peeled it all off the wall and have bare plaster again. So I am now not sure what to try or what caused this.

Hi,

I did brush down before applying and applied a coat of 3 water 1 part primer then a neat coat

theres your problem then brush off the dust and apply two coats or primer watered down rather then a neat top coat id use a BAL SBR primer

 

[chrisb1357]

But even the first coat did not soak into the plaster as when I removed it today the first coat which was water down came off as well with the neat coat

Do you suggest I do a test area but water it down a bit more like 4 to 1 instead of the 3 to 1.

Also it does not say on the primer how long before tilling to apply the primer and how long between coats

i use BAL primer so cant really say

but i tend to prime the walls giving it about 30min before 2nd coat id say
4 to 1 should be ok yer do a small test patch

Iv never had problems with BAL SBR soo id say use that
then give it 15 mins then start tiling while its still tacky or let it dry i like to get on it tacky but thats just me i guess

Umm

Well I think I left mine to long between coats. I did the water down coat one night left it overnight then the 2nd neat coat then left it a night before I was going to tile but I did not get as far as putting tiles on
