Megapoxy HT is a hydrophilic, non-sag epoxy gel for structural bonding and concrete repair where the surface is damp, wet or submerged. Unlike a runny injection resin, its gel consistency holds on vertical and overhead faces and can be applied in thicker layers.
Use HT to repair cracked concrete, bond new concrete to existing structures, grout suitable anchor bolts and attach steel to concrete in splash zones or underwater repairs. It also resists hydrogen sulphide found in sewage-treatment infrastructure.
Choose HT when the repair needs a gel that stays in place. Megapoxy H is the flowable liquid for wet-to-dry concrete bonding and epoxy mortars. Megapoxy HX is thinner again, designed to penetrate fine cracks rather than build up a surface repair.
Clean away weak concrete, grease and loose material. Mix three parts A to one part B by volume and use within 30 minutes at 25°C. Minimum cure is 24 hours at 25°C; do not apply below 10°C.
Can Megapoxy HT be used underwater?
Yes. The hydrophilic gel is designed for underwater, damp and splash-zone concrete repairs.
What's the difference between HT and Megapoxy H?
HT is a non-sag gel that stays in place vertically or overhead. H is a flowable liquid resin for wet-to-dry bonding and repair mortars.
How long can I work with HT?
Approximately 30 minutes at 25°C. Minimum cure at that temperature is 24 hours.
