If you want to modernise the look of a room, then you might want to get rid of the old-fashioned textured wall coating. Rather than spend hours scraping off the textured coating, you can cover the wall with a plaster skim-coating or specialty “smooth-over” filler designed for textured coatings. Use the supplied applicator to spread the filler over the textured coating to achieve a smooth finish on the wall. When the filler is dry, you can paint or paper the wall in the usual way.
Cover the floor and all furniture in the room with protective dustsheets.
Fill a bucket with hot water and two or three dashes of liquid detergent. Soak a clean cloth in the liquid solution and thoroughly clean the textured wall coating to remove dirt, grease and any loose particles.
Remove any nails, tacks or picture hooks with a pair of needle-nosed pliers. Fill any cracks in the textured wall with silicone-based crack filler. Wait for the filler to dry.
Stir the smooth-over filler to an even, creamy consistency in the supplied container.
Load the smooth-over filler onto the supplied roller or applicator. Usually you’ll need to immerse the applicator in the product.
Roll or spread the smooth-over filler onto the textured wall. Work away from the edges and towards the centre of the wall. Sweep the roller or applicator over the wall in a half-arc movement to achieve a smooth, consistent finish.
Wait for the smooth-over filler to dry. Drying times vary, depending on the manufacturer, so check the user instructions on the product container or label.
Sand away any tramlines or small irregularities in the wall surface with a fine-grade sandpaper or sanding block. You can now paint or paper the covered wall in your preferred style.
When cleaning the wall before applying the smooth-over filler, wash from the top and work down the wall. Use a stepladder to reach the top of tall walls, if necessary.
