No rising moisture according to ASTM (Polyethylene-sheet).

Before applying Sika® Ucrete® Industrial Flooring on Sika® Ucrete® PLC allow:

Note: Times are approximate and will be affected by changing ambient condition.

2 kg/mm/m²
2-4 kg/m²
5 - 10 m² / unit

Note:These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and
wastage etc.

Sika® Ucrete® PLC must be thoroughly mixed using a low speed electric stirrer (400 -600rpm) or other suitable equipment.

• Temperature will affect the mixing effect; the optimal temperature of the material itself before use is 15°C-25°C; if the application is in low temperature in winter, it is recommended to store the material in an indoor air-conditioned room at 15°C-25°C for at least 24h before use.
• Prepare the mixing container in advance; start the mixer: pour in Part 1 and stir for 15 seconds, then add Part 2 and stir for 20 seconds. Then slowly pour in Part 3 (powder) while stirring, the addition process takes about 15 seconds. Note that it should not be poured into the mixer quickly. After adding Part 3, stir further for more than 2 minutes to ensure that all powders and base materials are completely mixed.
• The mixing time should be consistent for each group of materials.
• During mixing, it is also necessary to use a straight-sided trowel to scrape off the ingredients (Part 1+2+3) that are stained on the sides and bottom of the container. This operation should be performed at least once to ensure complete final mixing. It is only necessary to mix all the ingredients in the factory package.

• Primer: Pour the mixed material immediately onto the floor and apply by steel trowel, working it well into the substrate in both directions to completely seal the floor. Fill in anchor grooves and finish to provide a continuous smooth even surface.
• Topcoat: Refer to the relevant PDS for application details and precautions.

Applicators must guarantee enough workers in large-area application. The entire process must be compact, and the transport of material between two mixing must be quick and ensure a wet joint, otherwise lap marks and color difference may occur.

Clean all tools and application equipment with Thinner C immediately after use. Hardened / cured material can only be mechanically removed.
