Product details Application Usage / application examples Notes

Field of application

Subsequent waterproofing of basements from the interior
Subsequent plinth waterproofing
Waterproofing of reservoirs against inside water pressure
Damp proofing for below ground waterproofing measures
Building elements in contact with drinking water
Salt-loaded substrates
WW waterproofing slurry as per DIN 19573

Properties

Very low emissions (GEV-EMICODE EC 1^Plus)
Water pressure tight
High sulphate resistance and low active alkali content (SR/NA)
Very good adhesion to the substrate
Enables water vapour diffusion
Chemical resistance according to DIN 4030 up to level of attack: XA2

Preparation
Substrate requirements

U1_M_46

Pre-wet highly absorbent substrates.

Preparations

Remove render and/or coatings at least 80 cm above the damaged area.

U2_M_175

Break off or chamfer corners and edges.

Use a suitable mortar to form inner corners as sealing coves.

Salt inhibitor

Pre-treat salt-contaminated substrates with Sulfatex LQ and Salt IH.

Exterior priming:

Prime mineral substrates with Kiesol (1:1 with water)/Kiesol MB.

Interior priming:

Prime mineral substrates with Kiesol (1:1 in water).

Waterproofing in drinking water areas

Apply three layers of material to the prepared, pre-wetted substrate without priming.
Application
Application requirements

Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C

Apply at least two layers of the material.

Bonding layer before render application
Apply another slurry layer of the product and apply render wet-on-wet.

Alternative: apply a slurry layer of the product, throw on SP Prep, apply render once dry.
Application instructions
Do not use in direct sunlight.

The maximum total wet coat thickness must not exceed 5 mm.

Once it has hardened, mortar must not be made workable again by adding either water or more wet mortar.

Protect the fresh waterproofing layer from rain, direct sunlight, frost and condensation water.

Once dry, protect from mechanical damage.

Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.
Working tools / cleaning
Mixer, ceiling brush, slurry broom

GR_HW_73

Clean tools with water while the material is still fresh.
Storage / shelf life
If stored in an unopened container and in a dry place, the product will keep for approx. 12 months.

Usage
Approx. 1.6 kg/m²/mm layer thickness
