Can you put pva glue on ply board

Question

I’m getting my floor tiled and I was told to buy pva glue but I’ve read that this should not be use what should I buy instead?

Matthew · Answer

It can be used as a primer as long as it is mixed 50/50 with water. It help control the suction from the background where the tiles are to be layed. Basically it is a cheaper way rather than buying the branded primers so it is in fact saving you money 💸.

Definitely not pva, buy sbr. Can get this from most hardware stores but also shouldn't be tiling onto plywood but instead use a cement board

No don't use PVA to the prime the surface before applying tiles, cause the acetic acid produced when cement and PVA come into contact would render the adhesive and grout useless. You can buy Mapei Primer G.

Pva is now recognised as an inferior bonding agent on which to tile. By doing this you are basically asking a thin coat of multi purpose glue to hold your tiles in place. You need to ensure that the plywood is fixed to the substrate extremely well then use a latex based primer followed by flexible adhesive and flexible grout

If you are doing only PVA over boards it's ok PVA sometimes is offering protection to the floor and a good grip when you are using PVA in your case the PVA protect the moister from the adhesive not to go inside the board and to have a good grip usual one floor you have to use a  to protect the board and when you have to use a self levelling compound  screed  give an extra time to the material to not dry fast in your case you can find a product from.mapey who can be used with no PVA

PVA is not a good idea you should use pro sealer which is a guaranteed right method it is a sealant waterproof and help adhesive get a better grip

Primer mixed with water all tile suppliers supply it.

Graham · Answer

PVA is not a suitable primer for tiling, buy 
Bond sbr by BAL.  Also, make sure you use a flexible adhesive.

William · Answer

PVA is an old outdated method of priming substrates for tiling. PVA is soluble so when wet tile adhesive comes in contact it basically turns back to liquid which is a weakness when tiles are applied over the top.
A good quality SBR primer is recommended by just about all adhesive manufacturers, they are available in any shop that sells tiling products and very simple to dilute and apply.

No don't use PVA you can use it 50/50with water but u don't get the same effect as the proper tile primer
