Sopro FDF Tanking Membrane

Sopro FDF Tanking Membrane is a Highly elastic, ready-to-use, one-component liquid waterproof coating for water-proofing indoor spaces to DIN 18 534 Part 3. Liquid admixture for tinting Sopro FDF flexible sealing compound to provide contrast colour for application of second membrane coat. To help distinguish between and keep a check on different membrane coats.

Used in moisture-exposed spaces not subject to hydrostatic pressure, e.g. bathrooms, showers, washrooms, and sanitary facilities. Suitable for Moisture Exposure Classes A (walls) to Construction Products List A issued by DIBt (German Institute for Construction Technology) and A0 to ZDB (Federation of the German Construction Industry) datasheet.

Technical Details for Sopro FDF Tanking Membrane

Coat Thickness See datasheet.

In compliance with good practice, liquid waterproof membranes shall be applied in at least two
coats using contrast colours.
Stated consumption rates are minimum values. Separate, good-practice evening out of substrate,
e.g. through application of a skim coat, is a prerequisite. Under DIN standards, an extra coat thickness
of 25 % is required for wet coat thickness.
FDF-KM 027: 1 ml contrast agent per 1 kg FDF 525/527
Drying Time Surface-dry after the first coat: 1.5 – 2.5 hours Surface-dry time after second coat: 3.0 – 5.0 hours
Suitable Substrates Cement, lime/cement and eminently hydraulic lime renders, masonry cement, gypsum plasterwork,
gypsum plasterboard and gypsum fibreboard drywall panels, concrete, lightweight concrete,
aerated concrete, flush-jointed masonry, grade V 100 GE 1 particleboard to DIN 68763,
