How to spray drywall mud

Step 1. Cover up

Before the spay work, you should cover unnecessary areas like Windows, Doors, furniture, etc., and use tape on the wall or corner where you are not want to spay. The mud easily will stick to the surface, and it will be damaging to looks. 

Step 2. Ready the surface

You have to clean your wall properly. If there has old dust, clean it. Then take sandpaper, and lightly sand it. Remove all old peeling paint from the wall.

It is a very primary step, If you do it properly, your job will be long lasting. On the other hand for wrong work, the mud will peel off soon.

Step 3. Prepare mud

Mixing mud and water with proper thickness is quite important. This thickness always depends on your work.

Take a 5-gallon bucket. Put the compound/mud there. You need little water and should be careful about it. Take very little water one time like 50 ml for 1 kg compound. Then use the mud mixer drill for blending. Then, if you see the mud thickness is not ready, again use 50 ml of water and blend it. Repeat this process until your mud thickness is not ready.

If the mud is too watery, you need to mix more compounds to fix it. That will be costly. So you should follow the method to save your money.

Spray each wall surface properly. Although, if you make a small mistake, that will be fixed in the next step.

Step 5. Finishing

After spraying the mud, all surfaces are not smooth, and some spots can have no spray mud properly. So take a scraper. Apply it for making very surfaces equal. 

After finishing, wait to dry. If the weather is good, this mud will be dry within 12-24 hours.

If your test is okay now you can start to spray mod on the wall. Keep a distance of 18 to 20 inches from the wall to the sprayer. Maintain the same distance when you spray all over the wall. Spray tine coat. Use a wet mil thickness gauge to count the thickness of the mud. If you finish spraying all over the surface, give it time to dry like 6-12 hours.

Step 4. Apply second coat

After drying the first coat of spray mud, now is the time to apply the second coat. You do not need to follow any specific method for creating a second mud. You can use the first apply mud in the second coat. 

Take the air sprayer. Apply the spray as the first coat method. And make sure to use again wet mil thickness gauge to measure the thickness.
