Application

Concrete construction joints in water reservoirs and sewage treatment plants.
Swimming pools, basements and retaining walls.
Lift shafts, tunnels, culverts and service pits.
Construction joints and movement joints where only nominal movement is anticipated, such as basement and retaining-wall joints.

Select the waterbar profile for the project joint design and expected movement. The V-profile should not be treated as a universal solution for movement joints.

How to Use

Fit the V-profile into split formwork or shuttering so it is cast centrally into the stop-end.
Use the pre-punched outer-flange eyelets and tie wires to secure the waterbar to steel reinforcement, preventing displacement during concreting.
During the first concrete pour, ensure the cast-in portion is well embedded. Vibrate carefully to avoid honeycombing. Use well-graded aggregate and concrete that is neither too plastic nor too stiff.
Maintain equal concrete pressure on both sides of the waterbar during placement to prevent displacement or folded edges.
Remove formwork carefully near the waterbar. Inspect the stop-end for honeycombing, repair as necessary, and remove hardened concrete remnants from the exposed waterbar before the second pour.
Complete the second pour with the same care so both sides of the waterbar are properly embedded.
For site welding, heat both cut ends simultaneously against the faces of a Sika electric welding knife until an even molten PVC bead forms. Withdraw the knife, immediately press the ends together, and hold rigid until cool and solid.
Inspect welded joints for gaps and imperfections. Redo defective welds; irregular cut edges, insufficient heat and dust can cause failures.

Specifications

Brand: Sika
Model: Sikafloor CureHard-24
Composition: Sodium silicate water dilution
Pack size for this listing: 15L container
Colour: Clear
Density: 1.2 kg/L at +20°C, EN ISO 2811-1
Solids content: 24% by mass
Shelf life: 24 months from production
Storage: Original unopened, undamaged sealed packaging in dry conditions between +5°C and +40°C. Follow the packaging and current Safety Data Sheet.

Application

Horizontal old or new concrete requiring a hardened surface with light to moderate abrasion resistance.
Dust-proofing prefabricated concrete elements.
Industrial, commercial and public buildings.
Interior and exterior use.

New concrete must first be cured for at least 7 days using water spray, blankets or plastic sheets. This treatment does not compensate for poor concrete with low cement content and is not intended for lightweight, extremely porous or worn surfaces with exposed aggregates. It does not hide serious staining or excessive wear.

How to Use

Ensure the substrate is structurally sound, clean and free of contaminants. Completely remove existing curing agents, membrane-forming sealers and asphalt, which impair penetration.
For hardened or old concrete, clean with high-pressure water or a suitable cleaning machine, allow to dry completely, and remove remaining dust and loose material by brushing or vacuuming.
Use thoroughly cleaned, high-volume, low-pressure spray equipment. Do not use sprayers previously used for silicones or release agents.
Apply a continuous film and touch up dry spots. Scrub into the surface with a soft-bristle broom or floor-scrubbing machine for at least 30 minutes, until the material gels and becomes slippery.
Lightly wet with a water spray and rework for another 10–20 minutes. After about 20 minutes, when it returns to a gel, rinse and remove excess using a squeegee, wet vacuum or mop. Do not allow excess or residue to dry, as white stains may require mechanical removal.
Apply a second coat on porous, rough-textured or brush-finished surfaces after the first coat is dry and tack-free.
Protect treated concrete from moisture for at least 3 days to prevent efflorescence. Immediately wash overspray from glass, aluminium and highly polished finishes to prevent etching.
Above +25°C, store material in a cool place before use and add material as needed to keep the surface wet during scrubbing. Below +10°C, thickening can make spraying difficult.
Before applying a subsequent coating system, mechanically abrade the cured surface using the appropriate light-to-heavy shot blasting for its penetration depth.

What's in the Box

One 15L container of Sikafloor CureHard-24. Spray equipment, brushes, floor-cleaning machinery and other application tools are not listed as included.

Technical Information

Consumption on power-trowelled concrete: 0.15–0.25 L/m² per coat, approximately 4–7m²/L. Theoretical figures exclude porosity, profile, level variations and wastage. Apply a test area to establish actual consumption.
Application air and substrate temperatures: +5°C to +35°C. Maximum relative humidity: 100%.
Waiting times at 50% relative humidity: approximately 3.5 hours at +5°C, 3 hours at +10°C, 2 hours at +20°C and 1.5 hours at +30°C. Subsequent coating still requires the specified mechanical preparation.
Manufacturer-listed full cure: approximately 6 hours at +10°C, 5 hours at +20°C and 4 hours at +30°C. Moisture protection for at least 3 days remains necessary.
Touch-dry at +20°C: approximately 2 hours. Maximum sealing and hardening at +20°C: approximately 7 days.

Direct UV exposure from sun, lamps or skylights may cause discolouration or colour deviation. Sika states this does not affect coating function and performance. A smooth gloss coating is not automatically slip-resistant; select the appropriate aggregate-based system.

How to Use

Confirm the prepared substrate's moisture content, air humidity and dew point. Substrate moisture must be below 4% by weight with no rising moisture. If it exceeds 4%, assess the specified Sikafloor EpoCem temporary-moisture-barrier system.
Apply at air and substrate temperatures of +10°C to +30°C and no more than 80% relative humidity. Keep the substrate and uncured floor at least 3°C above the dew point.
Stir part A mechanically. Add all of part B at the specified 79:21 ratio by weight and mix for 3 minutes using a low-speed stirrer at 300–400 rpm. Transfer to a clean container and remix until consistent. Avoid overmixing and air entrainment.
Prime with the specified Sikafloor-161 HC or Sikafloor-160 HC system to achieve a continuous, pore-free surface. Apply a second priming coat if necessary. Level rough surfaces first with an appropriate levelling mortar.
Apply roller coatings crosswise with a short-pile roller. Apply seal coats with a squeegee followed by crosswise back-rolling. Follow the selected smooth, textured or broadcast system build-up.
Observe the relevant primer-to-coating and coating-to-coating waiting windows before subsequent layers.
Clean tools immediately with Thinner C. Hardened material requires mechanical removal.

Application

For concrete sloped roofs using the reinforced membrane system, parapet walls, external walls and sealing joints, laps and roofing screws. Sika also describes use as a waterproofing and decorative finish on corrugated metal sheets; iron and steel must be free from rust before application.

How to Use

Prepare a clean, sound and properly cured surface. Remove loose material mechanically, preferably with a wire brush. Remove rust from iron and steel.
On porous substrates, prime with Sika RainTite diluted with 10% water at approximately 0.3 kg/m². Allow more than 3 hours to dry, depending on ambient conditions.
Without reinforcing membrane, apply two coats by brush or roller at approximately 0.3 kg/m² per coat.
For the reinforced system, apply a first coat at 0.8–1.0 kg/m². Embed Sika RainTite membrane while wet, smoothing out air pockets and creases. Overlap adjacent membrane by at least 50mm.
Immediately apply a second coat at 0.8–1.0 kg/m² while the first coat is wet, fully saturating the membrane from both sides. Once dry, apply a top coat at approximately 0.4 kg/m².
Protect from rain until dry. Clean uncured material with water; cured material requires mechanical removal. Follow the current Sika Product Data Sheet for the chosen system.

What's in the Box

One pail of Sika RainTite in the selected colour and 4kg or 20kg size. Reinforcing membrane and application tools are not listed as included.

Shelf life: 12 months from production in properly stored original unopened, undamaged sealed packaging
Storage: Dry conditions at +5°C to +30°C

Application

Roof waterproofing in new construction and refurbishment.
Roofs with complex geometry, many details or limited access.
Life-cycle extension of failing roofs after appropriate assessment and preparation.
White reflective roof coatings to help reduce solar heat gain.

Use reinforcement at movement-prone areas, irregular substrates, cracks, joints, seams and details. Sika's substrate instructions require reinforced systems on cementitious substrates and fully reinforced systems on suitable bituminous felt and coatings. Do not substitute a simple unreinforced coating where reinforcement is required.

How to Use

Assess the substrate and existing roof system. New concrete must cure for at least 28 days and have pull-off strength of at least 1.5 N/mm². Mechanically remove laitance and weak material, expose and repair defects, level surfaces and remove contaminants.
Ensure brick and stone joints are sound; secure tiles and slates and replace damaged sections. Abrade glazed tiles. Bituminous felt must be sound and bonded or fixed. Do not coat sticky or mobile bituminous surfaces, volatile mastics or old coal-tar coatings. Prepare metal to bright, sound surfaces and secure timber roof decks. Existing paint must be firmly adhered with oxidised layers removed.
Confirm substrate moisture below 6%, no rising moisture, and no surface water, moisture or condensation. Apply at air and substrate temperatures of +15°C to +35°C, relative humidity no more than 80%, and surface temperature at least 3°C above the dew point.
Stir for 1 minute with a drill and paddle until homogeneous. Avoid overmixing and air entrainment. On concrete, application during stable or falling temperatures helps reduce outgassing.
Prime with Sikalastic-590 diluted with 10% water at approximately 0.3 kg/m². Allow the primer to dry tack-free.
Where the unreinforced system is appropriate, apply two coats at approximately 0.5 kg/m² each, observing the drying periods.
For the reinforced system, apply an initial coat at approximately 0.3 kg/m², then an embedment coat at approximately 0.5 kg/m². The initial coat may be omitted only where the substrate is good and primer coverage and consumption are sufficient, as permitted by Sika.
Roll Sika-120 Reemat into the wet embedment coat, fully saturating it and removing air. Overlap reinforcement by at least 5cm and wet overlaps sufficiently to bond. Apply approximately 0.5 kg/m² wet-on-wet over the reinforcement.
After drying sufficiently for walking and observing the reinforced-system waiting period, sand off any projecting reinforcement fibres and apply the final coat at approximately 0.3–0.5 kg/m².
Use a short-pile roller and suitable brush for details. Airless spray is listed only for roof coating systems, with at least two spray-applied layers. Minimum equipment parameters: 220 bar pressure, 5.1 L/min output and 0.83mm nozzle.
Protect the fresh coating while curing. Clean tools with water immediately after use; hardened material requires mechanical removal.

What's in the Box

One pail of Sikalastic-590 in the selected 4kg or 20kg size and colour. Sika-120 Reemat reinforcement, repair products and application equipment are not listed as included.

Technical Information
