FAQs
What is the mixing ratio for this primer?
This is a 4:1 system, meaning 4 parts filler to 1 part hardener by volume.
Can this be used on plastic surfaces?
Yes, but ensure the plastic surface is properly cleaned and treated with an appropriate adhesion promoter before applying the filler.
What is the recommended nozzle size?
A nozzle size of 1.6mm to 1.8mm is typically recommended for this high-build primer.
Does this require a thinner?
Yes, a compatible Mipa 2K thinner can be added to adjust the viscosity depending on your application preference.
Is it suitable for small spot repairs?
Yes, its versatile nature allows it to be used for both large surface coverage and smaller spot repairs.
Why is this primer black?
The black color helps in providing a better foundation for dark-colored topcoats and assists in spotting sand-throughs during the preparation process.
Troubleshooting
Poor flow and orange peel texture
Check your spray gun settings, increase the thinner ratio slightly, or verify that the air pressure is at the manufacturer's recommended level.
Slow curing time
Verify the mixing ratio with the hardener and ensure the ambient temperature in the workspace is within the recommended operating range.
Primer does not sand easily
Ensure the primer has reached full cure time as specified in the technical data; premature sanding can clog abrasive paper.

Setup, Compatibility & Care
To prepare the Mipa 4+1 Acrylfiller HS, you must mix it with the appropriate Mipa 2K hardener at a 4:1 ratio. Depending on the desired viscosity, use a compatible Mipa 2K thinner. Ensure your spray gun is fitted with a nozzle size between 1.6mm and 1.8mm for optimal atomization. After application, clean your spray equipment immediately with a high-quality gun cleaner to prevent the 2K mixture from hardening inside the fluid passages. Store the product in a cool, dry area away from direct sunlight, and ensure the lids are tightly sealed to prevent moisture contamination.
