Sulfatex Grout 25 kg

Details

Substrate preparation
All wall and floor substrates must be sound, load-bearing, free of substances with a separating effect and loose soft material. Old render should be removed at least 80 cm above the visible damp zone. The substrate should be cleaned and old coatings removed from the entire surface, e.g. by mist blasting (Rotec), also mechanically in small areas.

Interior waterproofing must be continuous and therefore interior dividing walls must be separated from exterior walls the width of a stone as far up as the render was removed. A 20 cm wide strip of the screed in the floor-wall connection area should be removed or, if the cellar slab leaks,
completely removed.

Partial leaking areas in masonry work, e.g. soft joints, the connection joint to the floor, horizontal joints with a barrier membrane, open cracks should be chiselled out at least 2 cm deep and pre-sealed with Kiesol and Remmers Rapid Hardener.

Cracks in concrete and, if necessary, the floor connection should be injected with Injection Resin PUR or elastically with Injection Resin 2K PUR.
Depending on moisture content and absorbency, the substrate may need to be pre-wet. Highly absorbent masonry work (e.g. dry sand-lime brick) should be pre-wet several times in advance!

The waterproofing should always be applied to matt damp but not shiny wet substrates.

Waterproofing and restoration

Deep protection priming: Kiesol diluted 1:1 with water is sprayed over the entire surface of the matt damp, clean substrate, avoiding excess material running down. After a short waiting time (at least 15 min.), work can be continued.

Levelling: In areas where there are indentations, e.g. broken out stone, chased out soft joint areas, missing areas, gravel pockets or coarse surface texture, Sulfatex Grout is brushed on as a bonding layer. Waterproofing Filler is applied directly, wet-on-wet, to the adhesive grout (even several centimetres thick). The repaired areas can be immediately levelled with a float, trowel, grated scraper or jointing iron to achieve a closed surface which is later worked over with Remmers Undercoat Render.

Place a sealing cove made of Waterproofing Filler along the wallfloor connection over the fresh layer of Sulfatex Grout. Work can be continued after 15-30 minutes.

Waterproofing: Pour 5.0 to 5.3 litres of water into a clean container. Add 25 kg Sulfatex Grout and mix intensively with mixing equipment for approx. 3 minutes until homogenous. Allow to mature for 2 minutes; then stir until the proper consistence for working has been achieved. The
quantity of water to be added should be observed! Immediately after mixing, Aida Sulfatex Grout is applied to the entire surface with a soft brush in a grouting procedure. After approx. 20 minutes (depending on the substrate), a second layer of grout is applied as before. In case of standing
seepage water or water pressureloads, apply three layers of Aida Sulfatex Grout. The grout should be applied with a minimum application rate of 2.0 kg/m² (> 1 mm thick layer)per layer.
