There’s no doubt that one of the best methods through which you can quickly beautify the interior of your home, is by plastering your walls. With the help of plastering, you can hide cracks in your walls and plaster can also assist you in making your home well insulated from the interiors.
Once you complete the plastering procedure, you can then move onto more interesting kinds of stuff like painting your walls. While all these can be excellent ideas, it's essential that before you proceed to perform any of the above-mentioned tasks, you need to first know when and how you can paint a newly plastered wall.
Always Wait Before You Proceed To Paint Your Plaster
When you newly plaster your walls, you can expect the walls to contain a certain amount of moisture present in them. So, even if you’re in a big rush to get your plastered walls painted, you shouldn’t do so because they need sufficient drying time so that paint can stick to it in a better manner.
While you may ask - how long? Well, GIB fixer in Waikato states that there are several factors for the same and some of them are briefly listed below:
The overall thickness of the plaster has been applied.
The amount of humidity that is currently present in the air.
Whether the home has a central heating system.
The current temperature of the room - whether it’s warm or cold.
Sometimes, it would be an ideal decision to delay your painting plans on new plaster, by almost three to four weeks. Such a time would be more than enough for the plaster to dry up completely. But, it should be realized that if the environment is damp, then the overall time might be extended to at least five to six weeks.
One of the best ways through which you can tell whether the walls are ready to be painted is by looking at the overall color of the walls. When the plaster will be wet, you’ll be able to see checkered, splotchy patterns on the surface. But, when the walls will dry out, an uniform appearance will be obtained.
Therefore, ensure that the entire surface of the plaster has been dried up before you begin to paint. When you paint too soon without sufficiently drying the plaster surface, there will be a chance of molds developing on your walls.
How Can You Prepare Your Walls Before Plastering?
It doesn’t matter whether you’re following a DIY process or hiring a professional interior painter, you need to first smoothen out the plaster surface before you can start painting on the same.
To smooth the surface, the best process that you can utilize is the use of sandpaper. Using simple sandpaper will be enough to remove such blemishes from the plaster surface. Ensure that the sandpaper you'll be using isn't too rough because using high-coarse sandpaper can destroy your plastered surface. So, purchase sandpaper that is less than 240 grit-rated.
Application Of A Mist Coat
Before you proceed to paint your plastered walls, it’s highly recommended that you first apply the mist coat. The mist coat can be defined as a weaker matte emulsion that will directly bond with your plastered wall surface.
To get the preparation of your mist coat ready, you first need to mix it with a bucket of four parts of mist coat along with one part of water. It’s suggested that you first cover your sets of furniture before you proceed to apply the coating. The coating will take 24-hours to dry up fully.
Application Of The Paint
Always remember to not use a certain type of paint that will not make the plaster breathe, such as silk or vinyl paint. These paints tend to trap moisture inside your walls and thereby damage your plastered surface. Finally, choose your color palette, and off you go.
