How to Paint Foam Insulation

What You'll Need
Small paint roller
Paint trays
Latex paint
Foam brushes
Water-based paint
Face mask

When foam insulation is already installed in a room especially the basement, this gives the kind of warmth the room is expected to be. When a basement wall is unfinished because the wallboard has not been installed, painting the foam insulation will do the job of making it look finished. When paint is applied to the foam insulation, it seals the foam as well as create an décor out of the plain foam insulation as this material is also used for home decors, costumes as a material for creating certain crafts. It is an inexpensive material and could be purchased in larger sheets. When painting the foam insulation, remember to initially prime the surface to cover up the foam.

Step 1-Sanding for Décor Purposes

Using sandpaper, sand the ends of the foam to make a smooth finish. It is advisable to wear a face mask while doing the sanding to protect small particles to get inhaled. The sanding of the foam insulation is only essential when doing crafts work or decors. When foam insulation is installed on walls, sanding is not necessary.

Step 2-Choice of Paint

Using a paint tray, put in gesso or latex paint into it. Then the paint roller should be coated evenly with the paint. The gesso acts as the primer. Do not put excessive paint onto the paint roller to avoid it from creating large amounts of paint drips. White latex paint that is water based can be used as an option to gesso when working on large areas.

Step 3-Painting Process for the Foam Insulation

Using a paint roller, apply coatings of gesso paint on the flat surface of the foam insulation. For those areas that are hard to reach like the corners, it is useful to use foam brushes instead of the roller. The appropriate foam brush should be used for these areas. With the gesso paint, the foam surface will get primed keeping the paint from being absorbed and eventually from being melted by the insulation. After painting is done, let it stand to dry completely.

Step 4-Application of Several Gesso Coatings

The application of several coats of gesso paint should be done on the foam surface to make sure that it is covered entirely. The right process of coating should be practiced. Do one coat at a time. Let it stand for some time to dry completely. When the surface is dry, the second coating can be applied. Keep doing the same procedure until the desired number of coatings is reached. To get a smoother and cleaner look, it would be good to apply sanding on the dried gesso marks.

Step 5-Water-Based Paint Application.

After applying the last gesso coating on the foam insulation and drying it, apply a water-based Latex paint of the preferred color onto the foam. Foam brushes or paint rollers may be used for his application. Determine how much coatings are needed for the coverage of the entire area.
