Tips to Remove Humps on the Drywall Joint after Painting

The process of repairing drywall must be done with precision and using the right building supplies Toronto. One small mistake such as failing to ensure the joint compound is evenly spread can result in an unpleasant appearance especially after painting the wall. The paint can have extra moisture which causes the drywall to appear poorly finished. The hump on the joint can be a small oversight that greatly interferes with the look of your drywall.

Before you wait to see the bubbles on the drywall tape after painting, it is important to do the right thing. You may be forced to repair the tape and this could mean having to remove the paint and start over again. Below are a few key tips to help you avoid making this mistake and how to fix humps that may form on drywall joints after painting.

Ensure the wall has ample time to dry

Drywall should dry completely before you begin applying any paint. When you have applied the joint compound or spackle, ensure that it is completely dry before you start painting over it.

Allow the paint to dry completely

Also, do not start repairing humps on the joints unless the paint is completely dry. If you notice there are humps on the wall that need major repairs, don’t rush into fixing them when the area is still wet.

How to repair the humps

You will need to gather the right building supply Toronto for this task. Identify the bubbled section of the drywall tape. Using a utility knife, cut out this section. Target the perimeter of the bubble and then pull out the hump. If you notice areas with loose drywall mud, you can quickly chip them away using a paint scraper. Do this gently so that you do not cause any damage to the surrounding area.

Start painting the repaired area

Before you begin painting, apply drywall primer on the area. This primer is designed to ensure the surface is well prepared for a coat of paint. Make sure the primer dries completely before you continue applying a coat of paint. The primer will make sure the tape sticks together with the joint compound avoiding moisture that causes further bubbling. This is particularly important if you are planning to paint the wall with gloss or semi-gloss paint.

Apply new joint compound

You can apply joint compound on the area where you removed drywall tape using a 4-inch knife. Afterwards, lay a new drywall tape on top of the joint compound. Make sure the tape is flattened out nicely using a knife. Apply another coat of joint compound on top of the drywall tape. Give it adequate time to dry. When dry, apply another coat of joint compound over it and then scrape that flat.

Sand the area

Do not begin sanding unless the area is completely dry. Depending on the building supplies Toronto you have with you, you can use a 120-grit sandpaper to give you a flawless finish. Make sure you are gently on the wall. Apply primer on top before you start painting the wall again.
