How to Use Flex Paste to Fix Holes on Drywall?

You can cover a hole in your drywall using flex paste in less than an hour instead of paying handsomely to get a repairer. 

However, you may need to work fast to avoid getting stuck with dry flex paste before the hole is successfully covered. 

Fixing the hole in your drywall with flex paste will require an absorbent patch for the best results. 

Below are the steps for fixing your drywall with flex paste; 

#1. Clean out the Hole in the Drywall

It is best to begin fixing a hole in your drywall by ensuring no paint chunks are in the way. 

Therefore, you would need to clean the hole out carefully, either by picking out the pieces with your hands or scraping them. 

After picking out the paint chunks, you can use a knife to clean the hole until everything is leveled carefully. 

Cleaning the hole before applying the flex paste ensures that your finished work is smooth. 

#2. Attach a Patch over the Hole in the Drywall

The next step is to attach a patch over the hole in your drywall because loading the hole with flex paste would be ineffective. 

Place the patch over the hole in the drywall to ensure it covers the hole and expands a little past it. 

You must ensure that the patch differs from the exact size of the hole in the wall. This is because a larger patch wouldn’t fall through the hole while you work. 

#3. Apply the Flex Paste Around the Hole

After successfully finding a patch that fits the hole in the drywall, outline the excess part of the patch on the wall. 

Next, set the patch aside and apply flex paste around the hole while adhering to the marks that fit the patch. 

Unfortunately, flex paste dries quickly, so you need to work with small bits at once and work fast. 

#4. Place the Patch and Apply a Coat of Flex Paste 

Immediately you successfully spread flex paste around the marked areas where the patch should sit and attach the patch to the drywall. 

Then, spread a coat of flex paste on the patch until it’s set. This first coat of flex paste ensures that the patch securely covers the drywall’s hole. 

#5. Apply More Coats of Flex Paste to Cover the Patch 

The last step requires you to cover the patch with flex paste so that the hole in your drywall is invisible. 

To cover the patch, you must apply more coats of flex paste around and over it in circular motions. 

Next, allow the flex paste to dry completely before painting the wall to your taste; the hole in your wall will be unnoticeable after this process. 

Can You Paint over Flex Paste?

You can paint over flex paste and enjoy flawless results, but you must wait until it is fully cured before applying it. 

However, flex paste takes 24 to 48 hours to cure fully, which may seem like a drag for some people. 

The curing time frame varies depending on the thickness of the layers and the weather condition but flex paste cures faster in humid environments. 

Unfortunately, if the 24 to 48-hour window closes and the flex paste still appears wet, you’re advised against painting. 

No matter how much of a hurry you’re in, painting over wet flex paint could ruin the entire drywall or surface.

A few types of paints are the best to paint over flex paste because they are waterproof. 

These paints include; urethane, acrylic latex, and Zinsser; if you pair these with a primer, you’ll have a fantastic finish. 

It’s great that you can paint over flex paste yourself, just as you can use flex paste to fix holes in no time.

Below are the steps for painting over a cured coat of flex paste; 

  • First, wipe the flex paste clean to remove dirt or debris.
  • Next, apply a few coats of primer to enhance paint adhesion.
  • Lastly, apply the paint to the surface following the manufacturer’s instructions.
