Exterior paint problems are quite inevitable, so knowing how to fix them will make it easier for you every time you have to deal with them.
Your home’s exterior can’t avoid suffering from sun exposure, rainfall soaks, and change in temperature.

However, if you have proper knowledge on how to deal with these exterior paint problems, you won’t have to worry about anything.

Here are 5 exterior paint problems and how to fix them in Shelby County, KY.

1.Peeling Paint

One reason for peeling paint is poor adhesion and it’s one of the most common exterior paint problems you may encounter in the future.

Causes of Peeling Paint

• Painting on an uncleaned surface
• Painting on a wet surface
• Painting on a shiny surface
• Blistering paint 
• Using low-quality paint

How to Fix Peeling Paint

• Scrape the peeling paint then sand the surface until it’s smooth
• Apply primer before painting the area
• Use the appropriate caulking product
• Use high-quality acrylic latex paint

 2. Mildew

Mildew is known for its gray, brown, green, or dark black spots on the walls of your home’s exterior. 

It is a fungus that feeds and grows on the paint film and caulk.

Causes of Mildew

• Poor ventilation
• Moisture
• Lack of sun exposure
• Not priming before painting
• Using low-quality paint

How to Fix Mildew

• Wear safety gears such as goggles and gloves as you scrub it with your hand with a trisodium
• Rinse with water and use a detergent solution to wash the area, then rinse it again with water.
• Don’t forget to prime before painting
• Use high-quality acrylic latex paint

3. Blistering Paint

Blistering paint is known as the bubbles or blisters underneath the paint film. 

It is small to medium in size, and most common in wood siding and trim.

Causes of Blistering Paint

• Painting when the surface is too hot, which causes the paint to dry too fast, trapping the solvent vapor in it.
• Painting on a wet surface, trapping the moisture, which causes the paint film to expand.
• Improper house ventilation can cause the moisture to escape through the walls, causing blistering paint.

How to Fix Blistering Paint

• Scrape blistered paint
• Sand to bare wood
• Let the wood fully dry before you start painting
• Apply paint when the heat coming from the sun is not too intense
• Don’t forget to prime before you paint
• Try putting siding ventilation

4. Rust Stains

Rust stains are the reddish-brown to black stains on the surface of your home’s exterior.

Usually, what causes this type of exterior paint problem is the wrong nails attached to the siding.

Rainfall soaks can make these steel nails oxidize and rust, which causes rust stains on your exterior’s surface.

Causes of Rust Discoloration

• Not using stainless steel nails to attach the siding
• Not hammering the nails properly, causing them to pop up from below the surface and have contact with air
• Too much sanding removed the galvanized coating on the nail heads
• The tannic acid from moist wood reacts with the steel nails, which causes black stains

How to Fix Rust Discoloration

• Make sure that stainless steel nails were used to attach the siding
• Hammer the nails properly so that they won’t pop up from below the surface, preventing them to have contact with air
• If you can’t extract a rusted nail, remove the rust by sanding it then apply a stain-blocking primer
• Use high-quality paint instead of the cheap but low-quality ones

5. Alligatoring and Checking

Alligatoring is the cracked pattern that looks like a reptile’s skin.

Checking is similar to alligatoring, but it is less severe and is known as the long, spaced cracks in your paint film.

Causes of Alligatoring and Checking

• Applying a second coat of paint over the first coat of paint that has not yet dried completely.
• Applying paint on an incompatible existing paint like a glossy paint
• Old oil-based paint has lost its elasticity, causing cracks as the temperature changes.

How to Fix Alligatoring and Checking

• Scrape the old paint then sand until smooth
• Apply primer before painting it with a flexible latex-based house paint
• Use high-quality paint
