How to Paint in Cold Temperatures

Applying paint in cold weather can be a problem.

Painting when the weather is cold can be a problem, as regular paint is not designed to work much below 50 degrees F. The cooler temperatures interfere with the curing process and the paint will not dry properly. Painting in colder weather can also result in the paint showing signs of damage shortly after application.

Things You'll Need

• Low-temperature paint
• Sandpaper
• Paintbrushes

Instructions

1. Purchase a specialized paint like Sherwin-Williams Low-Temp 35 that is designed to be used at temperatures as low as 35 degrees F. If you are using a primer, this will have to be one designed for lower temperatures, too.

2. Prepare the surface for painting. Sand the area until it is smooth. If there is mold in the area, apply a mold remover and allow this to dry completely before applying the paint. Make sure that the surface that you are going to paint is dry. Condensation is often a result of cold weather and if you try to paint over it, not only will the paint not dry properly, but mold will form underneath it and eventually show through.

3. Begin painting in the late morning, when the sun has had a chance to warm up the air a little.

4. Use the paintbrush correctly. In cold weather, even specialized paint does not flow as well as it does when temperatures are higher. It is vital that the brush is used carefully to avoid getting runs. Do not overload the brush with paint and wipe off any excess along the edge of the tin before applying. Use the brush in straight, regular strokes and make sure that you only move it in one direction. Use either an up-and-down or side-to-side motion, but not both.

5. Wait for the paint to dry before applying a second coat. The paint will take longer to dry in cold weather and you must be patient.
