Flowcrete Hydraseal DPM 12Kg is used when the substrate is damp and normal Flowcrete primers cannot be used. Hydraseal DPM 12Kg permits the installation of Flowcrete coatings on top of concrete substrates that have a relative humidity of up to 100%. However, the surface must be dry; no moisture may be visible on the surface.
Ratio of components
2.4 parts of Hydraseal DPM Base A are mixed with 1 part of Hydraseal DPM Hardener B, by weight.
2 parts of Hydraseal DPM Base A are mixed with 1 part of Hydraseal DPM Hardener B, by volume.
Add all of Hardener B to Base A. Mix with slow speed drill and helical spinner, taking care not to entrain air.
The recommended material and substrate temperature is 10 – 25°C, but no less than 5°C.
The temperature of the substrate should exceed the “dew point” by 3°C during application and hardening.
Temperatures should not fall below 5°C in the 24hrs after application
