PRIMING NEW PLASTER
« on: December 04, 2008, 05:51:39 PM »
Hi  all I have a new const.   4500 sq. ft job all thinset plaster .
I haven't worked with plaster in over 25 years. we use to oil base prime back then. I was wondering is there a good trustworthy latex primer for plaster now or should i stick with oil primer???

If the plaster is fully cured, I'd be confident in using a 100% acrylic primer like Ben Moore Fresh Start.

Agree with Prowall-  I work in plaster all the time, but it is usually old stuff.  All the good top line acrylic primers should be fine.

Old post but just browsing through... we use plaster all the time here in the UK... we give the plaster a "mist coat".  Basically a thinned down coat of emulsion (80/20).  With new plaster you should also use a matt(flat) emulsion as this allows the plaster to 'breathe'.

Please define "emulsion" for us, it is not a term we use.

Emulsions are water-based, with vinyl or acrylic resins added to make them more hard-wearing than traditional emulsions. This results in varying degrees of sheen in the finish; as the shine increases, the paint tends to be more hard wearing. The ranges usually offer matt, eggshell, silk, satin and full gloss.

i.e. the paint you stick on walls n ceilings.

Welllllll, if that is the definition, I spent  more that 20 years of my life emulsified or embalmed,or what ever, I wish I had those years back.

Thats right, not oil... just known as emulsion this side of the pond.  Just remember to use a flat paint on new plaster.  And thin down the first coat.  This adheres to the plaster better!

Yeah, I had a big job (nightmare) a couple years ago involving a designer from London. She would fly over every two weeks or so and screw everything up. Emulsion is our latex, just like mop boards are our baseboards.

I hit the quote button and type, what else am I supposed to do? This time I erased all the crap above your quote, maybe that is the answer. The 70's altering mind substances, + another 10 years of gin and jack,+ many years of oil based paint and original Kilz,Bin, etc, certainly have not helped the matter, + I believe this site just does not like me. :o :o : ::) ::)
