Resichem 577 Chem Screed – Chemical Resistant Epoxy Repair Mortar – 10 KG Grey

Description

Resichem 577 Chem Screed is a solvent-free, chemical-resistant epoxy repair mortar designed to rebuild uneven or damaged concrete surfaces exposed to strong industrial chemicals. Trowel-applied at 10–30 mm (3/8″–1¼”) thick, it cures to a high-strength, hard-wearing surface that resists 98% sulfuric acid, 36% hydrochloric acid and 75% phosphoric acid.

The three-component system (base, activator and graded aggregate) is mixed with a drill and paddle, spread with a trowel or squeegee, and takes foot traffic after 24 hours and forklift traffic after 48 hours at 68°F, minimizing downtime in busy process areas.

Product Benefits

• Exceptional Chemical Resistance – Resists 98% sulfuric, 36% hydrochloric and 75% phosphoric acid.
• High Build – Apply 10–30 mm (3/8″–1¼”) in a single application to level uneven concrete.
• High Strength & Hard Wearing – Built for forklift and heavy-traffic areas.
• Fast Return to Service – Foot traffic in 24 hours and forklift traffic in 48 hours at 68°F.
