Product Description:
SikaLatex® SP is a synthetic rubber emulsion for adding to cement mortars, where good adhesion and water resistance are required. It is suitable for tropical conditions.
Usage:
A high quality emulsion that substantially increases the qualities of cement mortars such as:
- Thin layer patching mortars
- Renders
- Floor screeds
- Concrete repair mortars
- Abrasion resistant linings
- Tile fixing mortars
- Masonry mortars
Features / Advantages:
- Extremely good adhesion
- Reduced shrinkage
- Greater elasticity
- Excellent water resistance
- Increased abrasion resistance
- Improved chemical resistance
- Non-corrosive
- Ready for use
- Does not re-emulsify, even in high alkaline conditions
Shelf Life:
12 months from date of production
Storage Conditions:
Store properly in original, unopened and undamaged packaging in dry conditions. Keep away from direct sunlight.
Application Guide:
Mixing :
- Sika Latex SP is to be added to clean mixing water within the range of 1:1 - 1:2:5 for all applications, apart from sprayed-on renders, where a bonding slurry should be appplied.
- Subsequent mortar application must be carried out while the bonding coat is still wet.
- Aggregates should be well graded and thoroughly washed. Sand particle sizes should correspond to the thickness of mortar to be applied and required surface finish.
Application Steps:
Step 1 : Pre-Application
The concrete must be clean, sound an d free of all loose and friable material, cement laitance, oil, grease, etc.
Absorbent surfaces should be saturated thoroughly.
Step 2 : Mixing and Application
For Bonding Slurry:
SikaLatex® SP : water = 1:1, mixed with fresh cement to a creamy consistency, should be brushed onto the prepared surface.
For High Performance Render:
- Mix SikaLatex® SP : water in a 1:1 ratio.
- Use a maximum of 25L of this solution in a mix containing 50kg of cement and 150kg of sand.
- This will yield approximately 100 litres of mortar which will cover 10m² to a thickness of 10 mm.
