[proview1122]

hi can I use cementone addmix sbr (as I have 4lts left from a job) as a new plaster primer or should I use the proper bal or mapei primer

also what's the best flexibility additive for bagged powder adhesive. (bought non flexible by mistake and to far to take back)

cheers

Cementone SBR is fine for priming the walls, but i wouldn't start mixing random add mixtures with the adhesives. Stick to the recommended add mix that is suggested by the manufacturer.

Sbr can be added to cement based adhesive mix it 2 water to 1 sbr and it will stick like sheet to a blanket

If you decide to use sbr in your mix, keep your tools clean otherwise they will be a nightmare to clean if it sets hard....
