Areas of application
BORNIT® Slurry SF is used for waterproofing horizontal and vertical surfaces made of concrete, masonry or cement plaster. The product can be used for sealing of walls and for tank sealing.
Sealing with BORNIT® Slurry SF must only be applied to building structures, where any formation of cracks is not to be expected.

Type and properties
BORNIT® Slurry SF is a cementitious, hydraulically reacting powder with capillary blocking and crystallising agents for mineral waterproofing of building structures against soil moisture, seepage water and pressing water. BORNIT® Slurry SF can be used on the negative side (water penetrating from the rear) as well as on the positive side (side facing the water).
The rigid seal achieves good resistance to chemical and mechanical stresses. BORNIT® Slurry SF is free from soda and chlorides and is sulphate resistant.

Advantages
  • waterproof after drying out
  • environmentally friendly as it is solvent-free
  • vapor diffusion tight
  • easy to process
  • mineral substrate for subsequent products
  • safe protection also against pressing water for negative and positive side

Surface
The mineral substrate must be clean, firm and free from separating substances, oils and greases. Voids and depressions must be removed. Masonry must be fully grouted. The substrate must be moistened prior to application. Standing water must be removed. Dusty and salt-damaged substrates must be primed with BORNIT® Basic Primer. Rigid mineral sealing slurries are not capable of bridging crack formation. Therefore, it must be ensured that no crack movements occur in the substrate.

Processing
For processing BORNIT® Slurry SF, in principle, the current “Guideline for planning and execution of waterproofing of building components with mineral sealing slurries” must be observed.

Mixing:
Mix BORNIT® Slurry SF with clean tap water into a smooth, spreadable compound. The powder is added to the water in portions under stirring.

Mixing ratio:
Mix the 25 kg bag contents with approx. 8 l of tap water.
or
Mix the 25 kg bag contents with approx. 6 l of tap water plus 1-2 kg of BORNIT® Stick Emulsion.
Adding BORNIT® Stick Emulsion to the mixing water increases the water retention capacity and prevents burning up of the slurry in warm weather.

Application:
Apply the slurry with a wide, firm brush onto the plaster or concrete in at least 2 coats. Between applications of the individual coats, at least 3 hours, at most 24 hours should pass.
The provisions of DIN 1045 must be complied with, i.e. avoidance of heat, frost and strong wind during execution and at least 24 hours thereafter. Keeping the applied layer moist can be omitted, when at least 15 % of BORNIT® Stick Emulsion were added to the mixing water.

Combined waterproofing:
BORNIT® Slurry SF can be applied directly under thick bitumen coatings (BORNIT® 1C and 2C Thick Bitumen Coating, BORNIT® Profi 1C Express, BORNIT® 2C Flex Thick Bitumen Coating, BORNIT® Profi Hybrid 2C, BORNIT® Mineral Flex 2C). This pre-treatment reduces the risk of blistering in the polymer-modified thick coating on porous substrates and excludes the risk of water ingress at problematic wall/floor connections. Apply BORNIT® Slurry SF directly onto the fully grouted and void-free masonry. After a drying period of min. 24 hours, the thick bitumen coating is applied.

Negative-side waterproofing:
Brittle, loose joints must be cleaned and closed flush with the surface with BORNIT® Sealing Mortar. Following thorough hardening of BORNIT® Sealing Mortar, the surface to be waterproofed is primed with BORNIT® Basic Primer (consumption: min. 120 g/m², for highly absorbent substrates up to 250 g/m²). After a waiting period of at least 30 minutes, the first coating with BORNIT® Slurry SF is applied (consumption: 1.5 kg/m²). The second waterproofing layer of BORNIT® Slurry SF is applied after approx. 30 to 60 minutes (when the first layer of the waterproofing cannot be damaged by the application of the second layer anymore). Here, consumption likewise amounts to 1.5 kg/m². Final bonding takes place with a last application of BORNIT® Basic Primer (consumption: min. 250 g/m²).

Consumption
combined waterproofing: approx. 1.5 kg/m² (1 coat)
negative-side waterproofing: min. 3 kg/m² (2 coats)
