hello

1) I have some mapei primer G, shall i give it a coat over some plasterboard prior to tiling and if so what are the reasons for this?

2) Im using large ceramic tiles in a bathroom. for adhesive i was thinking cementious (not repidset) should i need flexible?

thanks

I would give it prime just in case you have any bare gypsum showing.

Use a single part flexible

as whitebeam says , would,nt hurt to tape and skim over joints with addy as well

ahh both good advice., yes ill defo tape and skim joints.

ill use my primer, 50.50 watered mix.

and im gona use mapei kera flex (not rapidset).

thanks

p.s if i use mapei primer g and then mapei keraflex and them BAL grout. would i not be covered by mapei in the eventuality of any problems because i switched to BAL for the grout.?

thanks

imho , i would say no . but the eventuality of there being a problem is doubt full ,bur better safe than sorry

haha and then an hour later i get a text saying hes bought tubbed granfix for me to use after i repeatedly told him i needed cementious addy. -?
