Earlex Viscosity Cup - Ford #4

A viscosity cup indicates whether a spray material is too thick or too thin. Testing viscosity before spraying ensures the material atomizes correctly and sprays evenly for a smooth finish.

Correct viscosity ensures the material being sprayed atomizes correctly and sprays evenly. Material that is too thick won't atomize properly, while overly thin material can cause runs.

Thin the paint as necessary using water or relevant thinners until the viscosity is correct. Always test before spraying. Browse wood stains & finishes that suit your project.

Yes. The Earlex viscosity cup is an essential accessory for HVLP spray station guns, helping you set the right material consistency. Explore matching spray finishing systems.

Yes. Materials should be tested before spraying to see if thinning is required, since the right viscosity is key to even atomization and a clean coat.

Preparation is essential. Mask around the areas you are not spraying, confirm your viscosity is correct, and if you are new to spraying, practice for a few minutes on cardboard to develop your technique.

Fine mists generally dry faster than heavier coats. Applying lighter coats lets you build up the finish faster with less likelihood of runs. Allow drying time between coats.

It is made by Earlex, a maker of HVLP spray equipment. Find more compatible gear in our spray finishing systems collection.

Yes. Avoid spraying when it is windy, as wind can disrupt the spray pattern and affect the evenness of your finish.

Beyond correct viscosity, you'll want proper masking, drying time between coats, and good technique. Round out your station with finishing supplies from Infinity Tools.
