Prior to applying the final coats of paint, now is the time to caulk the corners. So fill and abrade using a fine filler and sandpaper, and mist coat any filled areas. Pay particular attention to corners, around electrical fittings, etc, where the plasterer may have experienced some difficulty with finishing due to getting trowels into tight areas. The mist coat should be applied as evenly as possible, and allowed to fully dry.Īt this stage, some minor surface filling may be required- any imperfections in the plastering will show up following the mist coat. This is called a ‘mist coat’, and will soak into the new plaster to form a key or primer prior to the application of the proposed paint system. When the plaster is fully cured and dried, it is essential that a thinned down coat (65% paint/35% water) of a non-vinyl emulsion is applied. Brush this off prior to applying any paint. When dry, new plaster will have a thin layer of dust on the surface. The introduction of heat must be considered with caution, and low background heating is preferable to turning the heating system up high, which can dry the plaster out too quickly and cause cracking.

The drying out of the new plaster will be enhanced significantly by increasing ventilation to the area- by opening windows and doors, and the introduction of a dehumidifier will help to remove moisture in the atmosphere. If the plastering has been carried out as a ‘skim’ to finish new plasterboards, or cover up/encapsulate artex, the drying times will be considerably quicker than the above application.

You should seek some professional advice from a damp course specialist if you have any concerns about damp. This system is carried out to replace plaster contaminated by hygroscopic salts (which will occur due to the action of rising damp) and will take considerably longer to dry out and cure, depending on the thickness of the masonry, and the thickness of the rendering/plastering system.

If the plastering has been carried out to an old property following the introduction of a chemical damp proof course, the plaster system used will include removal of the old plaster back to stone or brick, and 2 backing coats of sand and cement prior to the final plaster skim.

The colour will change from a dark pink to light pink, and the time it will take to dry will depend on the thickness of the plaster, the temperature within the building, and the amount of ventilation available. New plaster will need to be fully cured and dried prior to painting. How long does it take for the plaster to dry? That is why knowing how long plaster takes to dry is very important. After plastering a new surface, nothing would be more disappointing than painting it badly.
