503 Premium S.B.R. Bond Ratio for use as a primer

Travelcard

I must be dense, but I cannot find the ratio of SBR to Water for this make of SBR for priming walls. Despite looking at numerous product sheets and other info by Everbuild.

Can anyone advise?

Depends what your going over - and what your going over with.......

plaster?
Render?
Paint?
Filler?

Generally

5w - 1sbr for dusty/s**t substrate or thermalites

3w - 1sbr if not too bad

1w - 1sbr is a decent mix, controls suction very well


Neat if you want to get away with 1 application and really kill suction

really kill suction?

yeah that makes sense dipshit

you do know that suction is an important part of the keying process don't you?

lol this forum never fails to make you giggle
 
never had to completely kill suction in 40 years on anything.... you tell me sunshine what situation u would do it
On a sand and lime background (course stuff)when the lime finish top coat has failed and delaminated but the background is still solid.
There’s no suction on silk or gloss paint but rely on the adhesion of the pva or grit to hopefully keep the plaster on the wall/ceiling
