    Instructions for Use
     
    SURFACE PREPARATION
     
    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.
     
    APPLICATION
     
    Sika-Latex is generally added to the clean mixing water within the range 1:1-1:4. For all applications, apart from sprayed on renders, a bonding coat of Sika-Latex - 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.
     
    CURING
     
    Protect from wind and direct sunlight for at least 24 hours after application. For continuous submersion applications, allow the treated surface to cure for at least 48 hours before submerging.
     
    LIMITATIONS
     
    Do not use Sika-Latex and water as a bonding agent- always add cement.

    Ambient and surface temperatures must be between 5°C and 35°C during application.
     
    CLEAN UP
     
    Remove uncured Sika-Latex from tools and equipment with water. Cured material can only be removed mechanically.
     
    HEALTH PRECAUTIONS
     
    Exercise care, as with handling any chemical construction product.
