How To Paint Old Exterior Stucco

Preparing The Surface For Paint

One of the initial challenges you will face is keeping your surroundings clean. Spread over some drop cloths on the floor and other furniture you want to protect from paint. This will take you one step closer to preparing stucco for paint.

Consider Your Stucco Texture And Peeling Paint

There are several types of texture available. Before painting the right paint on your stucco surface, you must be sure of your stucco texture. Some paints may suit a specific stucco type. Some of the available textures are – cat face texture, dash finish, lace and skip trowel textures, and sand textures.

Also, if paints are peeling off your stucco surface, this means the area was not properly cleaned/ prepared, or repaired before painting in the past. In case it happens, you need to clean off all the peeled paint first. Wipe out the stucco surface clean and then prepare to paint.

Clean Or Pressure Wash Your Wall

You must also clean the surface out of dust and dirt.

For exterior sidings, you can apply a thorough power wash. When it comes to interior stucco walls, you can use a vacuum cleaner with a dust disposal bag to clean the area.

Note: A rough pressure power wash can often damage stucco walls as they are very porous and delicate. You must ensure a distance of 24 inches between the nozzle and the wall and maintain a 45-degree angle with equal streaming.

Inspect For Fixing Cracks And Other Imperfections

Cracks and other imperfections can often lead to peeled-off paints in the future. Hence it is very important to fix any remaining cracks before painting.

Use an elastomeric caulk to fill any remaining cracks on the stucco. If the crack is larger than 1/16 inch in width, then they will need patching help. With all the patches and caulk, you may need to wait a minimum of 10-15 days before applying paint on them.

If there is any loose stucco, use a putty knife to remove them. The wall should be clean and plain to get ready for a new layer of paint.

Remove Mold

When cleaning stucco walls for repainting, you must not leave behind any mold or mildew. If there are any grime, grease, mildew or mold development on the stucco wall, make sure to clean them with a quality degreaser or cleaner.

Once you clean and remove the mold with chemicals, leave the area alone for 24 hours. When it is completely dry, you can proceed.

Prime

The next step includes priming. Once you are done with the initial five stages, look for a quality acrylic masonry primer. Use a synthetic bristle paintbrush to apply the primer. When you are done with the primer, use a big napped paint roller to roll forth and backward.

Why use an acrylic primer? Because acrylic primer offers improved adherence to the uneven surface of the stucco.

To avoid any unexpected experience, apply two thin acrylic primer coats rather than one thick layer. Also, allow the proper interval between two stucco coatings of each primer layer.

Check The Weather

When painting something interior or exterior, always keep in mind, the sun is the ultimate best friend.

Take advantage of the world we live in. Before starting to paint, check on weather apps. Avoid cloudy and high humid days.

Full sun with a moderate breeze is always the best environment to do paint works. It will help dry faster.

Make sure the temperature remains between 50F-90F. And if you are letting it dry outdoors overnight, the temperature shouldn’t fall below 35F.

Find A Way To Reach Higher Areas

This goes well for single or semi-level apartments. What to do in the case of duplex or taller homes?

If higher walls in your home can be reachable with an ordinary ladder, use one of these to complete the painting job.

What happens if a regular ladder is not enough? In this case, you have to use scaffolding that will professionally help you paint stucco walls higher in your home.

Apply The Paint

Because stucco surfaces have different textures, you will need almost double the paint than plain paint jobs.

You should use specific elastomeric coatings, avoiding any exterior paint. They are specially made for stucco surfaces and offer extra protection for your stucco wall paint. Elastomeric paints lock the surface protection, and they can create your very own waterproof system on the surface if applied rightly.

Avoid painting with a brush. Stucco paint colors come best with rollers or air sprayers. Repeat the way you applied primers, using a roller or air sprayer only.

Get a hold of these essentials you will need for painting the stucco exterior. You will need them.

Tips On How To Paint A Stucco House Perfectly

How To Paint A Stucco House Perfectly

Need some smart hacks? Here are some tips on how to apply stucco paint for a perfect output.

Fill Up The Cracks

Masonry caulks are a must to fill up the cracks in stucco walls. This is because masonry caulks are textured and more elastic in nature. They already have sands inside them, unlike any regular caulk.

Apply Flat Paint On Stucco

Flat paints offer a smooth collaboration on the surface. Even if you miss any part, you can go back and apply flat paint without having any touch-ups or uneven parts.

Spray In Different Angles

Spraying can be challenging at some points. Stucco textures have an infinite amount of angles. Hence, you will need to keep one step ahead. While using an air sprayer, once you apply one fresh coat, use the sprayer randomly from different angles to cover any touch-ups or light spots.

Use A Cardboard

Painting on edge with an air sprayer can be really hard. Use cardboard to block another edge with the help of someone and air spray smoothly on edge.
