Why is it important to allow proper flash time between coats of paint?

Allowing proper flash time between coats of paint is crucial to prevent issues such as bubbling and lifting. Flash time refers to the period that allows the solvents in the paint to evaporate before applying subsequent coats. If a second coat is applied too soon, it can trap solvents and moisture from the first layer, leading to a range of surface defects. Bubbling occurs when trapped solvents expand under the layer, causing the paint to blister. Lifting happens if the top layer affects the previous layer’s integrity, potentially disrupting adhesion and causing the paint to peel.

By ensuring adequate flash time, you create a more stable base for each coat of paint, promoting better adhesion and a smoother, more durable finish. This practice enhances the overall quality of the paint job and can lead to a more professional, aesthetically pleasing result.
