What is the best method for damp proofing cement and concrete substrates with very high moisture?

With UZIN PE 480.

Long waiting times due to damp substrates, and the high associated drying costs, are a problem especially where there are time pressures. UZIN PE 480 is a epoxy damp proof membrane which is suitable for damp proofing cement and concrete substrates with very high moisture above 99% RH as long as any pools or standing water is completely removed.

Step by step guide:

Punch several times through the plastic plug and floor of the upper section of the combican using a metal spike (or screw-driver). Do not forget to wear protective clothing.

Allow the hardener to run completely into the resin container.

Mix both components with a mixing drill until both components are combined. Then pour this mix into a clean, empty container and mix once more.

Apply a even coat of UZIN PE 480 onto the damp substrate with a B2 notch sized trowel (min. 500 g/m²). Then roll over again with a UZIN nylon fibre roller. The UZIN Epoxy Accelerator can be added to UZIN PE 480 to accelerate hardening (lease observe the corresponding product data sheets).

Once dry apply a thin and even coat of UZIN PE 280 primer with a lamb skin roller or UZIN nylon fibre roller over the whole substrate. As UZIN PE 280 dries after 60 minutes (at 20 °C and 65 % relative humidity).

Mix the levelling compound UZIN NC 170 LevelStar with clear cold water. Use a powerful electrical hand mixer, e.g. the agitator Power X 1300 from WOLFF with the UZIN levelling compound stirrer, for mixing.

Apply the levelling compound UZIN NC 170 LevelStar to the prepared surface. The raking method (notch size R2) can be used as an alternative to levelling. The screed rake from the UZIN product range is recommended for this purpose.

We developed UZIN PE 480 for very damp substrates where the new floor needs to be installed quickly.
