Sika SikaCem 810 is a one component modified SBR polymer,blended with plasticisers and selected fillers. When diluted it produces a gauging solution for improving cementitious mixes.
Sika SikaCem 810 when added to water in the correct ratio, then mixed with Cement and Sand / Aggregate to is used to produce bond coat / slurry, renders and floor screeds.
- Improved Workability
- Improved Mechanical Properties, such as Abrasion and Impact
- Improved Resistance to Freeze / Thaw Cycles
- Reduced Shrinkage and Cracking
- Reduced Permeability
- Chloride Free
- Enhanced properties over unmodified SBR and Acrylic Resins
|Mixing Ratio By Volume||Mixing Ratio By Volume|
|Application||SikaCem 810 : Water||Cement : Sand : Aggregrate||Thickness Layer Range (mm)|
|Bond Coat / Slurry||1 : 1||1 : 1 : 0|
|Normal Duty Floor Screed / Floor Repair Mortar||1 : 3 - 1 : 4||1 : 3 : 0||12 - 25mm|
|Render||1 : 2 - 1 : 4||1 : 4 : 0||10 - 20mm|
SUBSTRATE QUALITY / PRE-TREATMENT
Depending on the application, the substrate should be sound and free of all traces of contaminants, loose and friable particles, cement laitance, oils and grease etc.
For structurally bonded situations, the substrate must be structurally adequate.
The substrate should be prepared by suitable mechanical preparation techniques such as water jetting, needle guns, blast cleaning, scabblers etc. and properly pre-wetted to a saturated surface dry condition.
SikaCem® 810 must be mechanically mixed using a forced action mixer or in a clean drum using a drill and paddle (max. 500 rpm). A normal concrete free fall mixer is NOT suitable. Mix SikaCem® 810 with clean water to produce a gauging solution in the correct ratio for 90 seconds. Add gauging solution to cement / aggregate mix until desired consistency is achieved.
APPLICATION METHOD / TOOLS
The prepared substrate should be thoroughly soaked with clean water until uniformly saturated leaving no standing water. Always apply mix ‘wet on wet’ to bonding bridge / coat. Re-apply if surface dries.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
