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
Normally in new plaster we use mis coat for first coat( this could be emulsion paint , mixing with water).
Sand all the walls and ceiling, check for any filling.
Apply two coats of top coats and walls will be covering in of.
Hi freshly plastered walls will require more paint on them than walls that have already been painted. Fresh plaster sucks in the paint.
Wall need be wash up.
Wall need to be dry after-switch heathing if need.
Wall need pr-court.
Good paint recommended.
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.
Yes apply a thin coat of PVA glue to the way to create a barrier leave it to dry then paint over
Hi if the walls have just been plastered i would maybe recommend lining paper on the walls then paint better finish
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.
Yes, definitely. All new walls or ceilings need to be primed, using for eg. the PVA primer. Depends from a kind of surface, its condition and its absorptivity, the PVA have to be diluted in the right proportion; water - PVA. Then only after when surface is dry we can paint first coat of the paint. To achieve a positive primed effect we have to ensure that the diluted PVA is in right proportion with the water. If is not diluted enough then it will not penetrate the surface on a proper deep as should and will only make a thin coat like a foil. That is unwanted effect. The primer has to penetrate the surface in order to make it stronger and isolate its imperfections in the form of discoloration, oily stains, rusty metal residues or other material fraction, which its surface differs from the rest. After the primer application we have a clean and homogeneous surface, ready to make our painting job clean and tidy.
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.
You need to mist coat the plaster first before trying to add top paint.
If the plaster was not painting before you need to do it mist coat first
Mix 30% water and 70% emulsion (white) together after you can apply 2 coats of normal emulsion
It may just need to be rubbed down, undercoat and then painted
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
On bare plaster it's best to white wash the walls and ceilings first with a watered down white emulsion
Yes it is...water paint down 50/50 and give walls a whitewash then paint as normal
Yes you need to size the wall first. I.e watered down mix then paint on or you can use pva, watered down. If you don't it will use more paint and peels like skin.
If its not been painted before then it very well may need 3/4 coats to take away the dull effect from the plaster. Regards
yes walls need more paint because they have never been painted
They probably didn't clean the wall properly or the pain is not that good.
Normal A1 painting 2 or 3 hands and will be done and you wont see any kind of dot in the wall
Is expensive but worthy it
It could be one of two things.
1. The wall has totally absorbed the mist coat/white wash over time, and another coat is required.
2. Needing more paint than usual..... Are you meaning white emulsion and if so are you using a trade/contract branded paint rather than spending that bit more money for a more thicker paint? Trade/contract paint tends to be watery. A good way to test the viscosity/thickness of emulsion paint in the superstore is to basically shake the tub from side to side. If it's heavy and not sloshing around inside then your onto a winner.
The first coat will be sucked in as its new plaster will need 3 coats in total
Yes, apply a miss coat, use contract Matt on, perfect for new plaster
Yes, it’s due to the wall being more porous. I recommend the first coat paint to be mixed with water( 50% - 50%).
The walls/ceiling should take 3 coats from bare plaster a prime/mist coat which should be thinned down Matt emulation then 2 coats of your finishing paint depending on your colour some colours will take more coats like reds and things like that
