Common Problems When Spraying Acrylic Paint (+ Fixes)

When spraying acrylic paint, several common problems may arise. Here are some of the common problems and  fixes to address them: 

Clogging

Clogging occurs when the spray nozzle gets blocked, preventing a smooth flow of paint. This can happen due to paint particles or debris in the paint or improper thinning. 

How to fix it

To fix this issue, you can try cleaning the nozzle by wiping it with a cloth or using an appropriate cleaning solution. Additionally, ensure that the paint is properly thinned to the recommended consistency for spraying, as thick paint is more likely to cause clogs.

Orange Peel Effect

The orange peel effect refers to a textured, bumpy appearance on the painted surface that resembles the skin of an orange.

This happens when the paint is applied too heavily or if the air pressure is too high, causing it to dry before it settles smoothly. 

How to fix it

Adjust the air pressure to a lower setting and apply lighter coats of paint. Moreover, ensure proper thinning and maintain a consistent distance from the surface while spraying.

Paint Sagging or Running

Paint sagging or running occurs when the paint forms drips or runs down the surface due to excessive application or improper spraying technique. This can lead to uneven coverage and an unprofessional finish. 

How to fix it

Thin paint coats, allowing each coat to dry before applying the next. Maintain an appropriate distance from the surface and use smooth, even strokes while spraying. If sagging occurs, you can try lightly sanding the affected area and reapplying the paint.

Dry Spray

Dry spray refers to a powdery or grainy texture on the painted surface caused by the paint drying before it reaches the surface properly. It is caused by improper air pressure, incorrect nozzle size, or spraying from too far away. 

How to fix

To resolve this problem, ensure the air pressure is correctly set for the paint and equipment being used.

Check if the nozzle size is appropriate for the paint viscosity. Spray from a closer distance to ensure proper paint coverage and adhesion to the surface.

Fisheyes

Fisheyes are small, crater-like imperfections on the painted surface, often caused by surface contamination or incompatible materials. It can occur if the surface has oil, grease, or silicone residue that repels the paint. 

How to fix it

Clean the surface thoroughly before painting to remove any contaminants. If fisheyes still occur, using a fisheye eliminator or adding a small amount of silicone-free flow improver to the paint can help improve paint adhesion and prevent fisheye formation.
