EQUIPMENT
MIXING EQUIPMENT: Electric double paddle mixer (>700 W, 300 to 400 rpm).
APPLICATION EQUIPMENT: Short pile roller.
SUBSTRATE QUALITY
Cementitious substrates must be structurally sound and of sufficient compressive strength (minimum 25 N/mm2), with a minimum tensile strength of 1.5 N/mm2.
Substrates must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
SUBSTRATE PREPARATION
IMPORTANT
Exposing Blow Holes and Voids
When mechanically preparing the surface, make sure to fully expose blow holes and voids.
- Remove weak cementitious substrates.
- Prepare cementitious substrates mechanically using abrasive blast cleaning or planing / scarifying equipment to remove cement laitance.
- Before applying thin layer resins, remove high spots by grinding.
- Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
- Use products from the Sikafloor®, Sikadur® and Sikagard® range of materials to level the surface or fill cracks, blow holes and voids.
Contact Sika® Technical Services for additional information on products for levelling and repairing defects.
SUBSTRATE PREPARATION OF NON-CEMENTITIOUS SUBSTRATES
For information on substrate preparation of non-cementitious substrates, contact Sika® Technical Services.
TREATMENT OF JOINTS AND CRACKS
Construction joints and existing static surface cracks in substrate require pre-treating before full layer application. Use Sikadur® or Sikafloor® resins.
MIXING
Higher Amounts of Sikafloor®-54 Booster at Higher Ambient Temperatures
If more than 2 % of Sikafloor®-54 Booster is added at ambient temperatures higher than +15 °C, the exothermic reaction increases and the product will start foaming very quickly.
Exothermic Reaction
Do not leave the mixed product in its container after the end of the pot life, as the exothermic reaction of the product leads to foaming.
At the end of the Product's pot life, fill the container completely with quartz sand to stop the exothermic reaction.
Note: To increase the viscosity of the Product you can add Sika® Extender T.
- Mix Part A (resin) for ~30 seconds.
- Add Part B (hardener) to Part A.
- Mix continuously for 3 minutes, until a uniform mix is achieved.
- If necessary, gradually add the required amount of Sikafloor®-54 Booster.
- If additional materials were added, mix for a further 2 minutes until a uniform mix is achieved.
- To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
- During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing.
APPLICATION
No Application on Rising Moisture
Do not apply on substrates with rising moisture.
Protect from Moisture
After application, protect the Product from damp, condensation and direct water contact for at least 24 hours.
Temporary Heating
If temporary heating is required, do not use gas, oil, paraffin or other fossil fuel heaters. These produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish.
For heating, use only electric powered warm air blower systems.
Pin Holes
If the Product is applied on porous substrates during rising temperatures, pin holes may form from rising air.
Apply the Product during falling temperatures.
Filling Pin Holes
If pin holes are present after the Product has cured, blistering may occur in the subsequent layer. Close any pin holes using the following steps.
- Lightly grind the cured surface.
- Apply a scratch coat consisting of the Product mixed with ~3 % of Sika® Extender T.
STANDARD PRIMER APPLICATION
-
Pour the mixed Product onto the substrate.
Note: The consumption is specified in Application Information. - Apply the Product evenly over the surface with a short pile roller or a squeegee.
-
Back roll the surface in two directions at right angles with a fleece roller.
Note: Maintain a "wet edge" during application to achieve a seamless finish. - If broadcasting is required, wait between 15 and 30 minutes, then broadcast the surface with quartz sand. Broadcast lightly at first, then to excess.
- IMPORTANT Confirm waiting or overcoating time is achieved before applying subsequent products (refer to the "waiting time to overcoating" section of Application Information). Once the product has hardened sufficiently, remove all loose sand with industrial vacuuming equipment.
