what I have been wondering about the tanking system is....... - Tile Advice

[Mr Tiler]

is it not the same principle as tiling onto paint? or using pva wich creates a skin on the surface you would tile onto? cheers

 

[DHTiling]

Certain paints you can tile onto and PVA isn't just that it skins is it ..? or did you not know that

 

[Qwerty]

Mr tea bag, with the substrate correctly prepared and primed, the tanking (paint on membrane) will adhere very well and above all not break down in water.

 

[Mr Tiler]

no dave I didn't know that mate whats the other reason/s? cheers

Have a look at this Ash, some bedtime reading http://www.tilersforums.com/tile-adhesive-grout/2511-p-v-versus-primers.html

thanks bri

 

[Mr Tiler]

yeh deffo some good reading thanks for the info dave.... so does the tubbed adhesive crystalize once set too or is it a different process? only askink because I read on here that the tubbed addy relies on moisture to evaporate in order to set but cement based is a chemical reaction to the water? cheers

 

[DHTiling]

Tubbed adhesive does crystallize into the capillaries of the plaster etc... hence why it is not necessary to prime..

Cement based , then you do prime to prevent a reaction between the gypsum and cement... this is primed and a mechanical adhere is created with reaction.
