Painting old or new plaster is never easy. You cannot start painting the plastered wall if the plastering material is still wet. Even if the wall is re-plastered, you have to give it sufficient time to dry naturally. Plastering material will always soak up excess water from the air.
To get the best results, you may have to allow it to dry on its own. Do not use any heat source to dry the walls. You can hire the best “plastering in Auckland” services to help you through the entire process. Professional wall plastering services are aware of the right time to get started with painting the walls.
Once the walls have been plastered, the professional team will follow simple steps before they can apply the paint layer. You can read the below content to get familiar with these steps.
Allow the plaster to dry
Always allow the plastered wall to dry before the painting task. It takes time for any plaster material to dry as the top surface is highly permeable. Even if you are not watering the walls, still the material will soak all moisture from its surrounding air.
If the plaster does not dry, it may not achieve a smooth finish. There are many elements including surrounding weather conditions, that will affect the plastering quality as well. In general, if there is less moisture in the air, the plaster will take at least four weeks to dry completely. You should have the natural flow of air indoors. Using heating devices may not prove much effective.
Apply mist coat
A mist coat is generally applied to the fresh new plaster. You can create any mist coat paint that will act as the base for the final paint layer. Do not apply a thick layer of paint if you are applying a mist coat. You can best make use of the emulsion paint to create your mist coat.
The paint can be light in the shade so it acts as the base for the final paint layer. You can also use primer as the base for the final paint layer. Waterproof primer is the best option. It will help in holding the paint layer on the surface of the wall. Professional plasterers often prefer using primer coating as the mist layer.
Once the mist layer is dried completely, you will have to sand the walls so a smooth texture can be obtained. Do not use harsh scrubbing sandpaper to perform this task. It is certain that you only want to remove imperfections from the top surface of the plastered walls.
Once the prep task is done you can finally apply the paint to the walls. If you paint the walls on top of the plastering layer, you can expect the best results. The paint will shine naturally. Plastered walls will easily soak up paint so it dries out quickly.
If the plastered walls are wet, then it may not soak paint material. The paint will simply peel off within a few days.
