Usage
- Waterproofing membrane for roofs, terraces, and balconies
- Below-grade waterproofing for basements and retaining walls
- Wet rooms, bathrooms, and podium decks
- Surfaces subject to crack movement and structural settlement
- Not suitable for water-retaining structures (RC tanks, swimming pools) or areas with permanent water immersion
Advantages
- High elasticity and crack-bridging capability
- Easy application by roller, brush, or airless spray – including vertical walls and ceilings
- Seamless, fully bonded waterproofing membrane
- One-part – no mixing required (except dilution for primer coat)
- Can be overlaid with cementitious screed after 48 hours
Packaging
- 20 kg / pail
Colour
- Black

|---|---|
| Ambient Temperature | +5°C min / +40°C max |
| Relative Humidity | Max. 80% r.h. |
| Substrate Temperature | +5°C min / +40°C max |
| Substrate Moisture | <6% pbw (no rising moisture – ASTM D4263) |
| Dew Point | Substrate and uncured membrane must be min. 3°C above dew point |
| Curing Time | Min. 48 hours at +25°C |
| Waiting Time After Primer | 30–60 min (min) / 2 days (max) at +30°C |

Consumption
- Standard system: ~1.5 kg/m² total (primer + 2 coats)
- Reinforced system: ~2.0 kg/m² total (primer + 3 coats + Reemat reinforcement)
- In hot/dry conditions (>40°C, ~50% r.h.), reduce to max. 0.5 kg/m² per coat or apply when temperature is below 35°C
- Figures are theoretical and exclude allowances for surface porosity, profile, and wastage
Application Steps
- Substrate Preparation: New concrete must be cured min. 28 days with pull-off strength ≥1.5 N/mm². Surface must be dry (<6% moisture), mechanically prepared to open texture, free from standing water, oil, grease, coatings, laitance, and loose material. Remove all existing membranes by industrial vacuuming. Repair blowholes and voids fully.
- Mixing: Mix Sikalastic®-110 manually or with a low-speed mixer until completely homogeneous before application.
- Standard Coating System: Dilute with 1 part clean water for primer coat (~0.2 kg/m²). Apply by short hair wool roller, brush, or airless spray. Allow to dry, then apply 2 coats of undiluted Sikalastic®-110 (~0.65 kg/m² each), ensuring each coat is completely dry before the next. Allow full system to cure 48 hours before screed overlay.
- Reinforced Coating System: Apply primer as above. Apply 1st coat (~0.8 kg/m²) and embed Sika® Reemat Premium-120 into the wet coating. Roll to remove bubbles and creases. Overlap edges min. 50 mm, borders min. 100 mm. Apply 2nd and 3rd coats (~0.5 kg/m² each). Allow 48 hours before screed overlay.
- Cleaning: Clean all tools with water immediately after use. Hardened/cured material can only be removed mechanically.
