GENERAL DESCRIPTION

Epoxy.com Product #899 is a 100% solids Low-Mod Low Viscosity Primer and Sealer. It may be used as a Primer for any Epoxy.com Products, as a stand alone sealer. It may also be combined with Epoxy.com Product #78 to form a Low-Mod mortar.

ADVANTAGES

• Moisture insensitive (cures on damp or wet surfaces)
• Withstands movement from thermal change
• Meets ASTM C-881 Type III, Grade 1 Class B and C std. spec.
• Low Viscosity - Excellent wetting properties
• Good shock absorption qualities
• Versatile
• Forms Virtual Moisture Barrier 

SURFACE PREPARATION

Surface must be clean and sound. Remove all dirt, laitance, grease curing compounds and other foreign matter by sandblasting, mechanical abrasion, or acid etching. Remove water and dust from all surfaces with an oil-free blast immediately prior to application.

MIXING INSTRUCTIONS

Temperature of Epoxy.com Product #899 must be 50 degrees F or above at time of mixing. Stir each component separately before blending. Mix two parts by volume of Part A with one part by volume of Part B for three minutes with a low speed electric drill motor equipped with a mixing paddle.

APPLICATION

Epoxy.com Product #899 can be applied with a brush, roller or squeegee when used as a primer or seal coat. For skid resistance, broadcast sand at a rate of 2 lbs. per square yard. For mortar applications finish surface with trowel. Prime surface to be patched with neat material. For more information before installing please see installation tips.
