• Thin layer patching mortars
• Renders
• Floor screeds
• Concrete repair mortars
• Abrasion resistant lining
• Tile fixing mortars
• Masonry mortars

Features & Benefits

The benefits of SikaLatex® include, but are not limited to the following:

Increases adhesion

• Reduces shrinkage and cracking
• Increases abrasion resistance
• Reduces permeability
• Improves workability
• Easy to mix and to dose
• Works on different substrates
• Non-toxic, non-flammable and non-corrosive

Application Instructions

Bonding Bridge:

• Mix SikaLatex® with water to produce a gauging solution in the correct ratio. Add gauging solution to cement-aggregate mix until desired consistency is achieved. The prepared substrate should be thoroughly soaked with clean water until uniformly saturated leaving no standing water. Work mix vigorously with a stiff brush onto the pre-dampened substrate. Always apply screeds/render/mortars “wet on wet” onto the bonding bridge.

Substrate Quality/Pre-Treatment

• Concrete surfaces should be clean, sound and free from oil, grease, or other surface contaminants. Remove cement laitance and all loosely adhering particles using suitable mechanical means. Absorbent surfaces should be saturated thoroughly with water. Remove all standing water.

Applications Method/Tools

• SikaLatex® is generally added to the clean mixing water within the range 1:1 to 1:4. For all applications, apart from sprayed on renders, a bonding coat of SikaLatex® water 1:1 mixed with fresh cement, should be brushed into the prepared surface. Subsequently, mortar application must be carried out whilst the bonding coat is still wet.

Limitations

• Never use neat SikaLatex® or SikaLatex®-water mix as a bonding bridge, always add cement and sand.
