One sort of filler is spackling paste, which you can use in a variety of situations. And you can find spackle in many different types. Take note of the following:

  • Interiors typically benefit from the use of lightweight spackling. It dries rapidly, doesn't shrink, and sands readily.
  • Elastomeric spackle, which can stretch and contract, is the finest material to fill stress fissures and joints.
  • The use of vinyl spackle on outer walls and molding is satisfactory.

Why Is It Important To Prime Spackle Before Painting?

If you try to paint directly over the spackle without sanding it down or priming it first, expect to end up with a patchy, uneven finish and bare patches. Additionally, priming will significantly help in letting the paint adhere to the spackle. And if you apply the incorrect primer, the painted surface may have shiny patches. Expect this to also happen with the exterior spackle. 

What Is The Importance Of Hiding Spackled Areas?

It is a common misconception that painting over spackle will completely conceal it. You can't just color over the spackle patches, or they'll still be noticeable.

"Flashing" is a popular term to describe paint seeping through. Spots where you have applied spackle typically have a distinct roughness than the majority of the surface, adding to the wall's overall unappealing impression.

Know that merely painting over spackle patches makes them look even more monotonous than the surrounding wall, which can be unsightly. Making further precautions to safeguard the spackle and make it look better will make a massive difference in the room's overall look.

You might consider hiding spackle spots necessary if you wish to restore the appearance of your walls. And if you want to achieve excellent results, you can check and carefully follow the details below:

1. Make The Spackle Flush With The Wall

Because they aren't entirely level with your wall, spackle patches tend to stand out like sore thumbs. It results in projections that are highly visible and challenging to hide.

It is essential to have the spackle the same color as the wall so imperfections are less noticeable. In order to achieve this, you must first distribute the spackle outside the boundaries of the hole you desire to fix.

After applying spackle on the damaged wall, it is highly advisable to dry it thoroughly before you start sanding it. Sand the surface properly until you ensure that the spackle is entirely smooth and level with the wall. Additionally, checking it using your fingers instead of just looking at it would be best. 

2. Apply A Primer After Sanding

If you wish to conceal the spackle thoroughly, you should never skip this step. Applying primer is essential to ensure that the paint you apply will completely adhere to the surface, especially the spackle spot. 

If you apply spackle on the damaged wall, know that the spackle typically has a higher porosity than the surrounding wall. As a result, it will require you to prime the surface first before painting. 

3. Start Painting Over The Spackle's Surface

Covering the spackle with paint should begin with the patched area. Know that if you don't do this, the patched area will stand out from the rest of the wall's texture and look unprofessional. The outcome of this new texture will be a novel look.

The correct approach to this step is to first apply a thin layer of paint in the spackle spot. Remember that it is advisable not to paint the entire wall immediately. 

4. Continue Painting Until You Finish The Entire Wall

Please note that before you start painting the entire wall, it would be best to let the paint in the spackle spot dry first. You should not skip this step because it will help to allow the paint in the entire wall and spackle spot to be of the same shade.

Painting the entire wall at once ensures a uniform coat of paint that looks great. It can help immensely conceal the spackle and bring back the wall's original beauty. If you follow these instructions carefully, the spackled area should blend perfectly with the surrounding wall.

Although the abovementioned methods require elbow grease, especially in the sanding procedure, know that they will all be worth your exhaustion. It would be best to carefully follow these steps if you wish to achieve your desired results.

3. Sand And Smoothen The Spackle Spots

One of the things that you should never forget with this task is to use sandpaper to sand and smoothen the spackled areas. It is highly advisable to make the surface as smooth as possible. 

However, one key to remember here is to ensure that the spackle has thoroughly dried before you start sanding. 

The appropriate approach is to start sanding using light-grit sandpaper. Keep in mind that you should start with this one because you may immediately eliminate the unlevel spackle spot, leaving no damage to the wall surface.

Once the spackled surface appears smooth, smooth it again with the finest sandpaper. As a result, the paint won't seep into the spackled areas where it wouldn't belong.

4. Paint The Wall Surface

For the last step, it is a must to thoroughly wipe the wall to remove the dust or dirt that the sanding process produces. You can use a dry cloth first, then a wet cloth to ensure no dust will remain. After doing so, allow the wall to dry, and you may now add the coat of paint. 

When you dry the wall with a towel or sponge, the sandy feel will go away with it. Next, paint the wall as many layers as you desire. Moreover, get paint of the same color as the rest of the wall to avoid drawing attention to the spackled area.
