Painting over new plaster is tricky. You can’t just start painting over the plaster before leaving it to dry. Your job doesn’t just end there, painting over new plaster requires patience and determination. Getting the right brushes, rollers. Choosing the textures and applying them is difficult. But we will discuss all that today for you.
Letting the Plaster Dry
The very first thing you want is the plaster to dry, leaving it for a week should be enough, you can get faster drying if used a heater or airflow is allowed.
If you try to apply paint over wet plaster, problems like adhesion and uneven paintings can appear. Painting on dried plaster can also cause problems of its own. Using a mist solution is required before applying the final coat.
Mixing a mist Coat
A mist coat is a diluted emulsion coat, which gives the wall to soak something to bond with the paint. You can also use a water-based primer for the same effect. Ratios vary, but generally, 3 part of the emulsion is mixed with 1 part of water to make the mist coat. Use the same or a similar colour to use as a mist coat to get an even finish.
If you feel your mist coat is too thick, apply a little bit on the walls and check. Dilute it down even more with water to get the perfect coat.
Apply the mist coat
Mist coats are very runny, when using a roller, keep an upward motion to cover the whole wall. If you are using a paintbrush, cover the wall in a V shape motion. Whenever you see a drip, use the roller or paintbrush to run it over immediately, or it can ruin your topcoat. Wait for a day before applying the topcoat. Get a smaller paintbrush to get into corners.
No need to sand down your wall anymore, just use the roller or paintbrush to apply the topcoat in a v like motion for a perfect finish. If you are right-handed, start with the top left. If left, start with the top right. Allow the first topcoat to dry before applying the second.
It’s best to leave the painting to a professional. But, if you are determined to get your hands wet, do so carefully. Don’t let the fumes get inside your lungs and keep children away from the paints.
