How to Plaster a Wall

When your home needs to plaster a wall after water damage, it can be a challenge without professionals. Prepare the wall before plastering for the best results. Start by clearing the area around the wall. Remove furniture, decorations, and any obstructions. Cover the floor with a drop cloth to protect it from plaster splashes. Inspect the wall for any cracks, holes, or loose material. Use a filler to repair any imperfections. Sand the wall surface to create a smooth and even base. Ensure the wall is clean and free from dust, dirt, and grease.

Next, apply a bonding agent to the wall if it is old or smooth. This step helps the plaster adhere better. Mix the bonding agent according to the manufacturer’s instructions and apply it evenly with a brush or roller. Allow the bonding agent to dry completely before proceeding. Gather your plastering tools, including a hawk, trowel, mixing bucket, and plaster. Wear protective gear, such as gloves and safety goggles, to prevent injuries.

Prepare the plaster mix according to the manufacturer’s guidelines. Use clean water and a mixing bucket to achieve the right consistency. The mix should be smooth and free of lumps. Stir thoroughly to ensure even distribution of the plaster components. Once the plaster is ready, you can move on to applying the first coat.

Applying the Base Coat

Apply the base coat of plaster to create a strong foundation. Load your hawk with a generous amount of plaster. Use the trowel to scoop the plaster from the hawk and spread it onto the wall. Start at the bottom and work your way up, applying the plaster in even, sweeping motions. Keep the trowel at a slight angle to spread the plaster smoothly and evenly.

Cover the entire wall with the base coat, aiming for a thickness of about 5-7mm. Work quickly but carefully to avoid letting the plaster dry before you finish. Use long, continuous strokes to ensure a uniform application. Smooth out any ridges or uneven areas with the trowel. While you are in this position, make sure to check for mold contamination as well.

After the initial setting time, use a straight edge or darby to level the plaster. Place the straight edge against the wall and move it up and down to remove high spots.  Repeat this process horizontally to ensure a flat surface. Allow the base coat to dry slightly but remain damp to the touch before applying the second coat.

Applying the Finish Coat

The finish coat gives the wall a smooth and polished look. Prepare the plaster mix for the finish coat, ensuring it is slightly thinner than the base coat. Load the hawk and trowel with the plaster as before. Apply the finish coat in thin, even layers, aiming for a thickness of about 2-3mm. Start at the top of the wall and work your way down, using long, smooth strokes.

Maintain a consistent angle with the trowel to achieve a smooth application. Overlap each stroke slightly to avoid visible lines or ridges.  After the initial setting, use a clean, wet trowel to smooth out the surface. Apply light pressure and use sweeping motions to remove any imperfections.

Continue to smooth the plaster until you achieve a uniform finish. Allow the finish coat to dry for about 30 minutes, then perform a final smoothing pass with a damp trowel. This step helps to achieve a polished and even surface. Once the plaster is fully dry, which may take several days, you can proceed with painting or decorating the wall.

By following these steps, you can achieve a professionally plastered wall. Proper preparation, careful application, and attention to detail are key to success. With practice and patience, you can master the art of plastering and transform the walls in your home. If your home is in need of a new paint job, contact ASAP Restoration for help today!
