Concresive Liquid LPL (Long Pot Life)

Description: A 2-component, 100% solids liquid epoxy bonding agent designed for application in warm environments or where a long working time is needed.This creamy high build liquid bonds to damp concrete surfaces. May be extended with properly graded sand to provide an epoxy mortar.

Application: Bond fresh concrete to existing concrete. Grout bolts, dowels and rebars into concrete, stone and masonry. Fill joints and voids in masonry. Bonds concrete to dissimilar materials such as steel and wood. Excellent for coating rebar.

Applicable Standards: ASTM C-881, Type II, Grade 2, Class B and C.

Duralprep AC

Description: A 3 component, pre-proportioned, water based epoxy modified portland cement bonding agent and anti-corrosion coating. Used as a bonding agent for placing fresh concrete to existing concrete and for repair and restoration of concrete surfaces. Contains a unique migratory corrosion inhibitor which protects reinforcement when used as an anti-corrosion coating for steel. Has a long open time, is non flammable, VOC compliant, and does not form a water vapor barrier after cure.

Application: Used as a bonding agent for fresh concrete to existing concrete, concrete repairs, and as an anti-corrosion coating for steel reinforcement. Can be used for exterior or interior, on grade or above grade applications.

Coverage: Coverage rates are approximate, and for estimating purposes only. Surface temperature, porosity, and texture will determine actual material requirements. One full kit of will cover approximately 60 ft². Test the area prior to application to determine effective coverage rates.
As a bonding agent:
60–80 ft²/gal
As an anti-corrosion coating:
60–80 ft²/gal/coat
2 coats recommended.

Masco Hi-Mod

Description: A 100% solids, 2-component, moisture insensitive epoxy resin system. Has a unique hi-modulus of elasticity which allows for structural bonding of dry and damp materials free of hydrostatic pressure. High structural bonding/grouting adhesive. Easy mixing ratio of 1:1 for the two components. Excellent bond to damp surfaces, insensitive to moisture before, during and after cure. Fast setting; provides high early strength within 24 hrs. Cures as low as 40° F.

Application: Designed to bond fresh plastic concrete to structural sound hardened concrete. Excellent structural adhesive for bonding hardened concrete to hardened concrete and other structural materials. May be used as an epoxy mortar for patching spalls on dry or damp surfaces. Also used for grouting bolts, dowels, and pins.

Applicable Standards: ASTM C-881, Type I, II, IV, V; Grade 2, Class B & C, AASHTO M-235-86.
