While repairing cracks on paint work is essential, some people are hesitant because 
hiring someone to do it can be costly in these times. However, the following techniques will show you how to do it.
Required Tools and Materials
Scrapper
Cement grouting
Paint
Gypsum gauze
Adhesive
Filler
Sandpaper
Primer
Step 1
Begin by taking off any ornaments around on the wall. Before any work is done, a proper assessment of the extent of the damage is needed. Once you have an idea, it’ll be easier to procure the necessary supplies.
Step 2
Use the scrapper to get rid of the filler. Rub it down. Keep using the scrapper until the crack becomes visible. When repairing cracks on paint work, it may be necessary to go 5 mm deep to get to the plaster.
Step 3
Get the cement grouting and combine it with paint. Follow the instructions that came with the grouting to get it ready. Keep mixing the two until the color resembles that of the wall. Fill the crack with this mixture.
Step 4
Put as much gypsum gauze as necessary to conceal the crack. Be sure the gauze has some adhesive. When you’ve put enough, allow it to dry for 60 minutes.
Step 5
When the gauze has dried, apply filler mixed with some paint on it. Those who are repairing cracks on paint work should apply the filler paint as uniformly as possible. The spread should be at least 500 mm. You can make this bigger if you want. Allow this to dry for an hour.
Step 6
Look at the crack. If it’s well covered, you can start rubbing in the sandpaper. Add some more of the filler and use the sandpaper as you did before. By this time the entire surface area should be smooth.
Step 7
Apply primer on the surface. Let it dry. Apply a coat of paint. Allow it to dry for 45 minutes or an hour. Add more coat layers if you want.
Tips and Warnings
For those repairing cracks on paint work for the first time, it’s important you paint the surface evenly. An uneven paint or fill will create rough spots. The type of paint used is also vital. To help minimize repair work, keep in mind that typical house paint lasts for two to three years before retouching is needed.
Even if the paint looks okay, touching it up will keep it strong. You shouldn’t wait for the wall to deteriorate completely before working on it.
The most common reasons for cracking paint are plaster, slamming the wall with large objects and scratching.
Wear old clothes when working; you don’t want new clothes getting smeared with paint. Wear a face mask when painting so the paint doesn’t get to you. Do not use paint with lead.
Repairing cracks on paint work can be time consuming but it isn’t arduous or beyond your capability. This is a skill that’s worth learning, so you’ll never have to pay someone to do it again.
