How we install your cleanroom coatings system
25 years of best practices, executed the same way on every project. No shortcuts on prep, no cure-time surprises.
1. Surface Prep
Diamond grind, shot blast, or abrasive blast to ICRI/SSPC profile. Crack repair, joint detail, and substrate moisture testing.
2. Primer & Build
Manufacturer-spec primer applied at recorded DFT, followed by build coats matched to your traffic, chemical, and thermal load.
3. Finish & Detail
Topcoat, broadcast aggregate, cove base, and transitions installed to spec, with documented mil thickness throughout.
4. QC & Closeout
Pull-off adhesion testing, photo documentation, manufacturer letters, and warranty paperwork delivered at completion.
