How Do I Prime Newly Plastered Walls?


To prime a newly plastered wall, dilute the paint in the ratio of 1 part of water to 4 parts of paint. Apply this dilute paint to the newly plastered surface: add more water if the paint does not seem to be absorbed readily enough. You can hear the plaster suck the prime, if it is porous enough.

Priming or sealing means applying a coating which is diluted enough to enter the pours of the material with the emulsion or liquid with which it’s mixed. To seal a newly plastered or artexed surface on which you intend to put water based paint, eg matt emulsion, then mix some of that emulsion paint with a water at a ratio of 4 parts paint to 1 part water and stir thoroughly. Apply this to the surface and sometimes you can even hear the plaster or artex sucking up the liquid. If the plaster does not seem to be sucking up the liquid quickly, more water can be added to a maximum of 1 part water to 1 part paint.
