Product Description:

BORNIT® Slurry SF is a cementitious, ready- mixed waterproofer with hydrophobic properties. After hardening the slurry becomes to a watertight coating, at the same time providing excellent adhesion to all mineral substrates. BORNIT® Slurry SF has a significant abrasion resistance and is waterproof up to 14 bar.

Areas of Application:
BORNIT® Slurry SF is for the application to surfaces which have to be protected against the influence of water. The sealing is on the positive and negative side, that means against active and passive water pressure, possible. Due to the excellent bonding capability it is suitable to be applied on horizontal and vertical surfaces.

Surface preparation:
The substrate to be sealed has to be solid, clean and relatively even. The surface must be free from voids, cracks or ridges. Dust, dirt, grease, bitumen and oil have to be removed. The surfaces should be well pre- wetted and slightly damp, but not shiny wet at the time of application. Mineral (rigid) slurries are not able to bridge moving cracks. Therefore it has to be made sure that no crack moving appear in underground.
Give 25 kg of BORNIT® Slurry SF in a clean container, add approx. 7- 8 l of water and stir homogeneously with a slow speed mechanical mixer for at least 3 minutes.
Do not apply at temperatures below +5°C or above 40°C of air and surface. BORNIT® Slurry SF may be applied by trowel or brush. The mixture is applied in one coat against ground moisture ore non- pressure water and at least two coats in case of water under pressure. Apply the second coat earliest after 3 hours and latest after 24 hours.
The coat must be able to dry out completely for a minimum of 3 days before it comes into contact with water again.

This product must be stored cool and dry.
Shelf life in unopened, original packagings is at least 12 months.

Approx. 1,5 kg / m² at a 1 mm thickness of layer
Minimum thickness of layer:
1. Ground moisture and non-pressure water:     1,5 mm = 2 - 3 kg / m²
2. Water under pressure:                                         2,5 mm = 3 - 4 kg / m²
Maximum thickness of layer:                                   5,0 mm

Health and Safety:
BORNIT® Slurry SF contains cement. Irritating to eyes and skin. May cause sensitisation by skin contact. Keep out of reach of children.  Avoid contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable gloves. Provide good ventilation if inside.
