Diamond-Prime OSP®

 

DESCRIPTION: 

 

Diamond-Prime OSP is a low viscosity, 100% solids resin designed for use as a primer on concrete slabs that are contaminated with hydrocarbons, such as motor oil, solvents, cutting oils and hydraulics fluids. It possesses outstanding adhesion and surface tolerance making it ideal for challenging applications such as these. Diamond-Prime OSP also acts as a moisture tolerant primer to protect the new floor against vapor emissions and/or hydration from the concrete slab.

Modified Bisphenol A epoxy resin crosslinked with aliphatic polyamines.

LIMITATIONS: 

Concrete must be free of liquid hydrocarbon contamination. A test patch should always be performed to verify adhesion. Do not apply in temperatures below 50 F or above100F.

SURFACE PREPARATION: 

Concrete must be cured 30 days and be clean, and structurally sound, surface may be damp but with no visible water.  Surface must be degreased then shot blasted, diamond ground or acid etched to achieve an ICRI profile of CSP3 or greater. A properly prepared surface will have the texture of 80-100 grit sandpaper.  If the surface is diamond ground, use 20-30 grit diamonds and vacuum the floor twice to remove concrete dust.  Excessive dust in the pores of the concrete can compromise adhesion.  If acid etched, machine scrubbing is required.  Adhere strictly to guidelines listed in the DiamondStone Surface Preparation Manual
