Hi. Our house is 3 years old & just started painting first room. The wall has never been previously painted but just has the builders wash/plaster on it. However it seems that it’s needing more paint than usual. Is this due to the wall being more porous due to never being painted before. Many thanks for your help
Hello it would of been mist coated by the plasters and depending on colour can take 2 to 3 coats on top of the mist coat
Post your job & get responses from local tradespeople. Read reviews before you decide to hire.
Your walls have probably just a mist coat on them.
Just add another thin coat to walls before using your top coats, for a quality finish use quality paint/emulsion.
Hi freshly plastered walls will require more paint on them than walls that have already been painted. Fresh plaster sucks in the paint.
Yes that is correct , sme ways to deal with this . Use new plaster emulsion listed on container, dilute emulsion a little so it acts like a primer will make second coat easier to apply.
If there is raw plaster or plasterboard with joint filler you need to paint mist coat first and 2 coats of finish. For mist coat you can use the cheapest paint as a primer. But for new walls you need always more coats and more paint than for already painted surfaces.
It may just need to be rubbed down, undercoat and then painted
