Prepare the Wall Surfac
Before you can start plastering the wall, it is important to prepare the surface for a smooth finish. Follow these steps to ensure that the wall is ready for plastering:
1. Clean the Wall
Begin by removing any loose paint, wallpaper, or debris from the wall surface. Use a scraper or putty knife to gently scrape away any peeling paint or wallpaper. Use a vacuum or brush to remove any dust or dirt from the wall.
2. Repair Any Damaged Areas
If there are any holes, cracks, or other damage on the wall surface, you will need to repair them before plastering. Use a filler or joint compound to fill in any holes or cracks. Smooth the surface with a putty knife and allow it to dry according to the manufacturer’s instructions.
3. Sand the Surface
After the repaired areas are dry, use sandpaper or a sanding sponge to smooth the entire wall surface. Sanding will help to even out any imperfections and create a smooth base for the plaster.
4. Apply a Primer
Applying a primer will help the plaster adhere to the wall surface and provide a more even finish. Use a roller or brush to apply a coat of primer to the entire wall surface. Allow the primer to dry completely before moving on to the next step.
5. Protect the Surrounding Areas
Before you begin plastering, it is important to protect the surrounding areas from any splatters or drips. Use drop cloths or plastic sheets to cover the floor, furniture, and any fixtures that cannot be removed.
6. Wet the Wall Surface
Prior to applying the plaster, it can be beneficial to lightly dampen the wall surface. This will help the plaster to adhere better and prevent it from drying too quickly. Use a spray bottle to mist the wall with water or use a damp sponge to wet the surface.
By properly preparing the wall surface, you will ensure a better and more durable plaster finish. Take the time to clean, repair, sand, prime, and protect the surrounding areas before moving on to the next steps of plastering.
Gather the Necessary Tools and Material
