What is Sealer?
A sealer is a substance that’s used in painting to ensure a smooth and consistent finish. It’s applied before the main paint coat. The main role of a sealer is to provide a barrier between the surface that’s being painted and the paint itself. This barrier prevents unwanted elements like dust, moisture, or oils from interfering with the paint’s ability to adhere to the surface.
Sealer is especially important when painting surfaces like wood, concrete, or metal, which can react chemically with certain types of paint. By creating a barrier, the sealer helps to prevent these reactions. This ensures that the paint looks good and lasts for a long time. Using a sealer can make the difference between a paint job that looks professional and one that looks subpar.

Questions & Answers About Sealer
1. What is a Sealer in home painting and repair?
A sealer is something you put on surfaces like wood or concrete before you paint them. It stops the paint from soaking into the material and makes the surface smoother. This way, the paint sticks better and lasts longer.
2. Why should I use a Sealer before painting?
Using a sealer before you paint helps the paint look and last better. It stops the paint from soaking into the material, which can make the color uneven. It also makes the paint last longer and protects the surface from damage, like from water or mold.
3. How do I pick the right Sealer for my project?
Which sealer you should use depends on what you’re painting and how you want it to look. For example, if you’re painting wood, a sanding sealer can make the surface smoother. For concrete, a penetrating sealer is best because it soaks into the material and protects it from water and chemicals. Always check the product details and ask a professional if you’re not sure.
4. How do I use a Sealer correctly?
Before you put on a sealer, make sure the surface is clean and dry. Then, spread the sealer evenly with a brush, roller, or sprayer, following the product’s instructions. Let the sealer dry completely before you start painting. For the best protection and durability, it’s a good idea to put on two coats of sealer.
5. Can I paint without a Sealer?
You can paint without a sealer, but it’s usually not a good idea, especially if you’re painting something porous. Without a sealer, the paint can soak into the material, which can make the finish uneven and require more coats of paint. A sealer also protects the surface, makes the paint look better, and helps it last longer.
6. How often should I put on new Sealer?
How often you need to put on new sealer depends on what kind of sealer you’re using and what the surface has to deal with. Usually, you should put on new sealer every 1-3 years. If the surface has to deal with bad weather or lots of people walking on it, you might need to put on new sealer more often. Always do what the manufacturer recommends.
