Kiesol (30 kg)

Contents: 30 kg

Range of use

• Kiesol is a liquid combination product made of water repelling silicic acid compounds
• Water repelling, capillary narrowing, deep protection for waterproofing damp masonry work
• Protection against capillary rising damp through injection with Kiesol in a borehole procedure
• Diffusion open barrier zone (deep protection) against the effect of moisture from behind
• Improved adhesion by priming, diluted 1:1 with water
• Strengthens the substrate and increases chemical resistance through silicification
• Faster working operations through silicification treatments with waterproofing grouts (system waterproofing in one day)
• As a solvent-free, highly concentrated system component, Kiesol is environment-friendly and is thus also suitable for indoor applications
• Suppresses capillary water absorption according to WTA, tested up to a degree of 80% moisture penetration by injecting under gravity.

Directions
I. Refurbishment of old buildings: a) Borehole procedure "Injection of Masonry Work against Capillary Rising Damp" in ground floors and basements: Remove render and/or coatings at least 80 cm above the moist edge. Chase out damaged mortar joints up to 2 cm deep. Pre-wet dry areas and apply a silicification treatment consisting of Kiesol diluted 1:1 with water and Remmers Sulfatex Grout. Then close open joints with Remmers Waterproofing Filler. To inject masonry work in a borehole procedure against capillary rising damp, drill holes in intervals of 10-12.5 cm with a downward slope of approx. 25°, less for thicker walls and more for narrower walls. Depending on the procedure used, the diameter of the boreholes should be 10 to 30 mm. When drilling the holes, cross at least one horizontal joint, ending approx. 5 cm before the end of the wall.

Fill hollow masonry, e.g. double leaf cavity masonry with a loose core filling, narrow cracks, etc., with Remmers Injection Mortar first. At the earliest after 7 days (the Injection Mortar must have hardened), these boreholes are redrilled. In the case of extremely hollow masonry work, it is also possible to fill one row of boreholes with Injection Mortar first and then to inject with Kiesol 5 cm higher. Injection is made under gravity through suitable storage containers, e.g. for narrow walls up to 24 cm thick with an injection cartridge, otherwise with feeding devices, until the surrounding wall area is saturated. When a low pressure procedure is used (approx. 4-8 bar), light pressure injection packers or plastic packers are used: Injection equipment: Kiesol Surface Sprayer with coupling, Hübner Airless 1301 VP or Desoi Injection Pump DEMb03, Dittman Unipress.
Guide values for impregnation time with Kiesol:
30 sec. approx. 0.25 kg
1 min. approx. 0.5 kg
2 min. approx. 1.0 kg

For further details, read the information provided by the equipment manufacturer.

Supporting measures for masonry work injection:
- One silicification treatment as vertical surface treatment from the floor slab up to approx. 20 cm above the row of boreholes, using Remmers Preparatory Mortar
- Remmers Special Restoration Render

Substrate preparation: Remove old render at least 80 cm above the visible moisture edge. Chase out damaged joints 2 cm deep. Fill open joints with Remmers Undercoat Render. Coat wall surfaces up to 30 cm above the row of boreholes with Remmers Sulfatex Grout in the Remmers Kiesol System (mineral waterproofing with deep protection).
Below the horizontal barrier, separate the render in the floor connection by a joint and, depending on requirements, waterproof the floor surface. b) Subsequent basement waterproofing from the interior with a silicification treatment using Kiesol diluted 1:1 with water and Remmers Sulfatex Grout: Preparation of the substrate: All substrates must be sound, load-bearing and free of substances that could interfere with adhesion and loose or soft materials. Basement masonry work, interior: Remove old render at least 80 cm above the visible moisture edge. Remove old coatings and clean the entire surface, e.g. by mist blasting (Rotec), also mechanically on small areas. Indentations must be filled and masonry work made of cavity blocks with a very coarse surface texture (e.g. basement building blocks, slag blocks) must always be rendered first (Remmers Undercoat Render or Remmers Waterproofing Filler) and waterproofed after the render has set. Interior waterproofing is executed continuously. For this, separate interior dividing walls from exterior walls approx. the width of a block as far up as the render was removed. In the floor-wall connection, chisel out screed approx. 20 cm wide, or, in the case of leaking basement slabs, remove screed completely. Partial leaking areas in the masonry work, e.g. floor connection joints, horizontal joints with barrier membrane, are pre-waterproofed using Kiesol and Remmers Rapid Hardener and closed with Remmers Waterproofing Filler. Fill cracks leading water, construction joints especially in concrete with Remmers Injection Resin PUR or inject through packers. Pre-wetting the substrate: Pre-wetting is carried out, depending on the moisture content and absorption capacity of the substrate. Highly absorbent masonry work (e.g. dry sand-lime brick) should be pre-wet several times prior to treating!

The waterproofing should only be applied to matt damp substrates and never to shiny wet substrates. Directions: For subsequent surface waterproofing with deep protection, diluted Kiesol is used in combination with Sulfatex Grout, applying as a silicification treatment, wet-on-wet: Spray on Kiesol diluted 1:1 with water, covering the entire matt damp substrate. Spray only enough that it does not run down. After a waiting time of at least 15 minutes, brush on Sulfatex Grout over the entire surface in a grouting procedure. The grout should be applied in a minimum layer thickness of 1 mm. After this first silicification treatment, wait 20 minutes (depending on substrate) before applying a second coat of grout. For standing seepage water or water pressure, apply three silicification treatments using Sulfatex Grout. The minimum application rate for the grout is 2.0 kg/m² (> 1 mm thick layer) per coat. The total thickness of the layer of grout should not exceed 5 mm at any one place. Since future water loads may change, we recommend that three silicification treatments are always applied. Place a sealing cove in the floorwall connection made of Remmers Repellent Mortar or Remmers Waterproofing Filler. Then throw on Remmers Preparatory Mortar onto the last layer of grout, covering the entire surface. If the spritz is not applied the same day, apply another layer of Sulfatex Grout without using Kiesol and while fresh, throw on Preparatory Mortar. After setting, at the earliest after 3 days, apply render, using Remmers Special Restoration Render Restoration or Fast Restoration Render. Separate the render on the wall from the floor with a joint at least 1 cm wide. Never apply gypsum or lime render.
