Schluter KERDI DS Vapour Barrier Membrane

£555.84 (inc VAT)



Schluter KERDI DS is a waterproofing membrane and vapour barrier bonded to a tile covering, e.g. for use in swimming pools and spa areas, as well as for commercial applications with high humidity levels. Vapour barriers are suggested for moisture sensitive substrates such as wood, plasterboard and gypsum plaster.

Comes in 1m x 30m rolls.

Schluter KERDI DS is a special version of the standard Schluter KERDI 200 Waterproofing Membrane. Schluter KERDI DS is a polyethylene membrane for bonded waterproofing assemblies and serves as a vapour barrier with an sd value of more than 100 m, which is considered a vapour barrier in physical construction terms. The waterproofing membrane is 0.5 mm thick and equipped with water vapour blocking additives.

Schluter KERDI DS features imprinted gridlines on one side for easier cutting. In addition to indicating how much material is left, the imprint also shows the minimum overlap width of 5 cm for working with multiple membrane sheets.

Schluter KERDI DS should be bonded to an even, load bearing substrate with an appropriate adhesive. We recommend using a 4mm notch trowel (such as a Schluter TROWEL) to spread the bonding adhesive. The tiles are laid directly on the membrane using the appropriate adhesive and bedding for the chosen tile or stone. Other trowel applied covering materials or plaster may also be used.

Accessories for Schluter KERDI DS include internal and external corners – Schluter KERDI KERECK, as well as pipe collars – Schluter KERDI KM and KERDI MV. Sealing tape to seal butt joints or corner joints – Schluter KERDI KEBA, which comes in widths of 85mm, 125mm, 15mm, 185mm and 250mm. Schluter KERDI FLEX, in widths of 125mm or 250mm, is used to seal over expansion joints or flexible edge joints. When installing this membrane the joints should be overlapped by at least 50mm or abutted then fully covered with Schluter KERDI KEBA sealing band, using the sealing adhesive Schluter KERDI COLL L.

Since bonded waterproofing assemblies with Schluter KERDI DS do not have the necessary uncoupling function for screed and tile coverings in outdoor areas that are subject to temperature changes, we recommend using this product in conjunction with Schluter DITRA DRAIN or Schluter DITRA 25 for a combined bonded waterproofing and uncoupling function.

Schluter KERDI DS is waterproof and resistant to most chemicals commonly encountered in tiled environments. It is resistant to ageing, does not rot and is characterised by its elasticity.
The product is highly resistant to saline solutions, acid and alkaline solutions, many organic solvents, alcohols and oils. Information regarding its resistance to specific stresses can be provided if concentration, temperature and period of exposure are known.

Verify that the substrate on which the product is to be placed is even, load bearing and free from moisture. Surfaces which inhibit proper adhesion must be removed or appropriately treated.
