How Temperature and Humidity Affect Paint and Painting Application - temperature limits for latex based paint


Latex Specifications and Properties | Sciencing temperature limits for latex based paint

The maximum and minimum recommended temperatures for exterior paint vary depending on the type (oil or latex) and specific brand of paint used, but a general rule of thumb is that oil-based paint can be applied when the temperatures are between 40°- 90° F and latex between 50°- 85° F.

A: If you need to paint outside with latex paint when temperatures are moving up and down like a yo-yo, I suggest you use one of the latex like Duration, Resilience, or SuperPaint. These products can be applied and will cure at lower temperatures, as low as 35° F. Traditional latex-based paints need temperatures above 60° F to cure properly.

The rule of thumb is that if you are painting with an oil-based paint, the ambient temperature should be above 45°F for at least 48 hours. Latex and acrylic paints typically require higher temperatures above 50°F. it takes longer for the water in an acrylic or latex paint to evaporate. When you combine low temperatures and high humidity.

Solvent-based paints thicken in lower temperatures, causing stiffer brushing, heavier application and slower drying. This can mean paint runs, sags and wrinkling on vertical surfaces, plus an overall reduced rate of coverage per gallon. Below 50 degrees, latex paints dry more slowly, especially when high humidity is DIY Staff.
