How do you keep knock down texture from peeling off with paint application?

Answer 1

Use "all purpose" compound for the texture. It will be a little stronger than topping compound. You could also use "Hot mud", which is a LOT stronger and won't soften when it gets wet. Part of your problem is, you're using a water based primer or paint over the texture, then you're rolling it. Try either using an oil based primer or just spray the primer over the texture without using the roller. Once the PVA primer sets up the texture should be strong enough to take the finish coat without trouble.

What you need: * Acoustical spray gun * Compressor and hopper * Joint compound * Knockdown knife * Primer and paint 1. Get an acoustical spray gun to do the bulk of the work. Also get a compressor and a hopper, which can be rented from a hard ware store.

2. Mix joint compound and water. Make a mixture that is thin enough to flow through the spray gun but thick enough to stick to the wall.

3. Put the mixture into the spray gun. Spray a few pieces of paper to make sure the nozzle is on the right setting. Adjust the nozzle and the compressor until you get the spray effect you desire.

4. Spray the walls, leaving a fairly even pattern. Allow the wall to have different thicknesses of the mixture, but keep one general look to the walls. Mix the smaller and larger blobs of the mixture instead of concentrating on the smaller blobs on one part of the wall.

5. Allow the joint compound to dry for about 20 minutes, until it is tacky but not dry.

6. Take a knockdown knife and slice through the joint compound blobs. Hit them quickly in order to knock the ends off without smearing the compound. Leave a rough texture on the wall and let the wall dry for at least a day.

7. Prime the wall and paint over the texture.

Knock down textured walls are quickly becoming a popular means to decorate the walls of a room. Once a person finishes the knock down texturing, he or she will need to paint these walls. When painting these types of textured walls, there are few differences in the tools and techniques from the traditional texturing on the walls of the past. Read on to learn how to paint knock down textured walls Purchase paint rollers that are thicker than normal rollers. Sometimes it will state on the roller if it is for use on knock down textured walls. If you can't find a roller with a label, buy the fuzziest roller available. Step 2 Buy enough paint that will coat the room twice. Because knock down texture absorbs so much of the paint, you will need to apply two coats of paint. Step 3 Apply painters tape to the edges of the painting area to create proper lines of delineation. You will need to tape off the ceiling and the baseboard if you are painting the walls. If you are painting the ceiling, you need to tape off the wall at the edge of the ceiling. This ensures that the room has a clear line of delineation between the ceiling and walls. Step 4 Sand down any rough area on the knock down textured wall. While you want to maintain the textured look on the walls, the texture can have some rough areas that you need to sand down so the paint will apply evenly. Step 5 Use the roller to apply paint to the walls. Pour some paint into a painting tray, dip the roller in the paint and roll off the excess on the tray. Then roll the paint onto the textured walls. Step 6 Let the paint dry and then apply a second of coat of paint with a roller. Be sure to notice and apply extra paint to any specific areas that have insufficient paint coverage. Step 7 Touch up any area that roller may have missed. Even after a second coat, there may be place on the wall where the paint coverage is lacking. To remedy this use a touch up brush to cover those individual areas. You may need to look at the wall from different angles to notice any spotty areas. Thanks for supporting my answers. Ask again!
