IMPORTANT
Protect from frost
Protect freshly applied material from freezing and frost to prevent cracking.
IMPORTANT
Application in the direct sun or strong winds
Avoid application in direct sun, strong winds or both to reduce the risk of the product cracking.
REINFORCEMENT CORROSION PROTECTION COATING
- Where a reinforcement coating is required, apply to the whole exposed circumference Sika MonoTop®-1010 or SikaTop® Armatec®-110 EpoCem®. Refer to the individual Product Data Sheets.
BONDING PRIMER
On a well prepared and roughened substrate or for a sprayed application, a bonding primer is generally not required.
When a bonding primer is required to achieve the required adhesion values, use Sika MonoTop®-1010 or SikaTop® Armatec®-110 EpoCem®. Refer to the individual Product Data Sheets.
REPAIR MORTAR MANUAL APPLICATION
IMPORTANT
Substrate pre-wetting
Insufficient substrate saturation prior to application will cause the mortar to not gain full mechanical properties.
- Only apply the product to stable, prepared substrates.
- Thoroughly pre-wet the prepared substrate for a minimum of 2 hours before application.
- Keep the surface wet and do not allow to dry.
- The final pre-wetted surface must achieve a dark matt appearance (i.e. saturated surface dry).
IMPORTANT
Sagging or slumping of built up layers
Allow each layer to slightly harden and remain wet before applying subsequent layers.
- Remove excess water from within the surface pores and cavities with a clean sponge.
- Make a scratch coat using the repair mortar.
- Apply the scratch coat over the complete substrate surface to form a thin layer to fill surface pores or cavities.
- IMPORTANT Do not apply as a 'feather edge'. Apply the repair mortar onto the scratch coat ‘wet-on-wet’ between the minimum and maximum layer thicknesses without the formation of voids.
REPAIR MORTAR SPRAYED APPLICATION - WET SPRAY
IMPORTANT
Substrate pre-wetting
Insufficient substrate saturation prior to application will cause the mortar to not gain full mechanical properties.
- Only apply the product to stable, prepared substrates.
- Thoroughly pre-wet the prepared substrate for a minimum of 2 hours before application.
- Keep the surface wet and do not allow to dry.
- The final pre-wetted surface must achieve a dark matt appearance (i.e. saturated surface dry).
IMPORTANT
Sagging or slumping of built up layers
Allow each layer to slightly harden and remain wet before applying subsequent layers.
- Remove excess water from within the surface pores and cavities with a clean sponge.
- Place the wet mixed repair mortar into the spraying equipment.
- Spray the repair mortar onto the pre-wetted substrate between the minimum and maximum layer thicknesses without the formation of voids.
SURFACE FINISHING
IMPORTANT
Adding water during surface finishing
Do not add water during the surface finishing as this can cause discolouration and cracking.
- Allow mortar to surface harden.
- Surface finish to the required surface texture using a stainless steel, steel, PVC or wooden float.
COLD WEATHER WORKING
Store bags in a warm environment and use warm water to assist with achieving strength gain and maintaining physical properties.
HOT WEATHER WORKING
Store bags in a cool environment and using cold water to assist with controlling the exothermic reaction to reduce cracking and maintaining physical properties.
