Sikalastic®-110
Sikalastic®-110 is a water based one part modified polyurethane/bituminous coating, formulated to form a highly elastic, seamless and crack bridging membrane.
- Easy application by roller, brush or sprayed, even onto vertical walls and ceiling
- High elasticity
- High crack bridging capability
- Optimum adhesion onto concrete
- Can be applied directly on damp surface
- Non-toxic
- Low VOC and eco-friendly
Usage
Due to its high elasticity, Sikalastic®-110 can be applied on different structures including those subject to thermal movement and vibration such as:- Concealed RC flat roof
- External walls to be buried below ground
- Waterproofing coating under tiles areas like podium, balconies and etc.

Applied Product Ready for Use
Sikalastic®-110 should be allowed to cure for min. 48 hours prior to overlaying with screed.
SUBSTRATE PREPARATION
- New concrete should be cured for at least 28 days and should have a pull off strength ≥ 1.5 N/mm².
- Substrate must be dry with < 6 % moisture and prepared mechanically to achieve an open textured surface.
- Substrates must be free of standing water (no puddles) clean and free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
- All existing coating / membrane, dust, loose and friable material must be completely removed from all surfaces before application of Sikalastic®-110, and associated system products, by industrial vacuuming equipment.
- The substrate must be sound and of sufficient strength. Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed.
- To confirm adequate surface preparation and product adhesion, carry out a trial before full application together with adhesion tests.
MIXING
Mix Sikalastic®-110 manually or use a low speed mixer until it is completely homogeneous prior to application.
APPLICATION
Sikalastic®-110 is applied using brush, roller or by airless spray.
Standard Coating System
Dilute Sikalastic®-110 with 1 part of clean water. Stir gently until the mix is homogenous and uniform colour is achieved. Using a short hair wool roller, brush or by airless spray, apply a layer of the diluted Sikalastic®-110 onto the substrate and leave the primer to dry before applying the first coat. After the primer has dried, apply another two layers of Sikalastic®-110 to the desired film thickness. Ensure the previous layer is completely dry before applying the next layer. Leave the whole system to cure for around 48 hours prior to overlaying with cementitious screed.
Reinforced Coating System
Dilute Sikalastic®-110 with 1 part of clean water. Stir gently until the mix is homogenous and uniform colour is achieved. Using a short hair wool roller,
brush or by airless spray, apply a layer of the diluted Sikalastic®-110 onto the substrate and leave the primer to dry before applying the first coat. Apply first coat of Sikalastic®-110 and embed Sika® Reemat® Premium-120 onto the wet coating, roll to ensure there are no bubbles or creases. The overlap between the edges shall be minimum 50mm and borders overlap by minimum of 100 mm. Subsequently, apply an additianal 2 coats of Sikalastic®-110 at desired film thicnkess. Ensure the previous layer is completely dry before applying the next layer. Leave the whole system to cure for around 48 hours prior to overlaying with cementitious screed.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened and/or cured material can only be mechanically removed.
