Product Information
Full details
The Indasa High Build Primer in Grey is a versatile one-pack acrylic-based solution designed for automotive and DIY enthusiasts who require a professional-grade surface preparation tool. It offers excellent adhesion and fills minor surface imperfections to create a smooth, durable foundation for topcoats; however, because it is a high-build formula, it requires careful sanding to achieve a perfectly level surface before applying color.

FAQs
Can I use this primer on bare metal?
It is recommended to use an etching primer or epoxy primer on bare metal first for corrosion protection, then use the Indasa High Build Primer as a surfacer.
How long should I wait before sanding?
Drying time depends on temperature and humidity, but it is best to allow the primer to cure fully for at least 4-6 hours, ideally overnight, before sanding.
Is this primer compatible with 2K paints?
Yes, once fully cured, this acrylic-based primer provides a stable base for most 2K topcoats, but always test on a sample piece first.
Do I need to thin this product?
This is typically a ready-to-use one-pack formula, but check the product label for specific technical recommendations regarding thinning for specialized spray equipment.
What grit sandpaper should I use for finishing?
Start with 320-400 grit for initial leveling and finish with 600 grit to ensure a smooth surface for your color coat.
Troubleshooting
Primer is running or sagging during application
Apply thinner coats and ensure proper distance between the spray nozzle and the surface.
Surface feels rough after drying
The product may have been applied from too far away; reduce the distance and ensure the surface is properly sanded before the next coat.
Poor adhesion to the substrate
Verify the surface was properly degreased and scuffed before application; check that no wax or silicone residue remains.
Pros and Cons
Pros
- High filling properties for hiding surface defects
- Easy one-pack application
- Superior bonding characteristics
- Creates a smooth base for professional finishes
Cons
- Requires proper ventilation during application
- Longer cure time compared to two-pack systems
- Heavy builds can be prone to sagging if applied too thick
Setup, Compatibility & Care
Before application, ensure the substrate is thoroughly cleaned with a degreaser and free of dust, oil, or loose contaminants. The surface should be scuffed to promote mechanical adhesion. While this primer is compatible with most acrylic and solvent-based topcoats, it is recommended to perform a test patch if you are unsure of system compatibility. Store the can in a cool, dry place away from direct sunlight, and ensure the lid is sealed tightly after every use to prevent the product from skinning or thickening.
