Beware of condensation.
The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the floor finish. Low temperatures and high humidity conditions increase the probability of blooming.

Select the most appropriate equipment required for the project:

Substrate preparation

• Abrasive blasting cleaning system
• Planing machine
• Scarifying machine
• High pressure water blasting system
• Other suitable equipment

Mixing

• Electric single paddle mixer (300–400 rpm)
• Forced action / rotating pan / double paddle or trough type mixer (300–400 rpm)
• Scraper
• Clean mixing containers

Application

• Mixed material carrier
• Pin leveller
• Trowels
• Spiked roller
• Squeegee
• Fleece rollers

Prior to mixing all parts, mix separately Part A (resin) using an electric single paddle mixer or other suitable equipment, mix liquid and all the coloured pigment until a uniform colour / mix has been achieved. Add Part B (hardener) to Part A and mix Part A + B continuously for 3,0 minutes until a uniformly coloured mix has been achieved. To ensure thorough mixing pour materials into another container and mix again to achieve a smooth consistent mix. Excessive mixing must be avoided to minimise air entrainment. 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. Mix full units only. Mixing time for A + B + quartz sand = 3,0 minutes.

Reference must be made to further documentation where applicable, such as relevant method statement, application manual and installation or working instructions.

Prior to application, confirm substrate moisture content, relative air humidity, dew point, substrate, air and product temperatures. If moisture content > 4% parts by weight, Sikafloor® EpoCem® may be applied as a Temporary Moisture Barrier (T.M.B.) system.

Primer

Pour mixed Sikafloor® primer onto the prepared substrate and apply by brush, roller or squeegee then back roller in two directions at right angles to each other. Ensure a continuous, pore free coat covers the substrate. If necessary, apply two priming coats. Confirm waiting /overcoating time has been achieved before applying subsequent products. Refer to individual primer Product Data Sheet.

Self - smoothing wearing layer
Pour mixed Sikafloor®-376 onto prepared substrate and spread evenly using a suitable trowel or pin leveller to the required thickness.
Spike roller immediately in two directions at right angles to each other to remove trowel marks, aid air release, ensure an even thickness and obtain the required surface finish.

Slip resistant broadcast layer
Pour mixed Sikafloor®-376 onto prepared substrate and spread evenly using a suitable trowel or pin leveller to the required thickness.
Spike roller immediately in two directions at right angles to each other to aid air release and ensure an even thickness. After the appropriate waiting time, broadcast with quartz sand, at first lightly and then to excess to produce an even distribution surface profile. Allow Sikafloor®-376 to initially cure and remove all loose sand by vacuum extraction equipment.

Seal / top coat

After waiting the appropriate overcoating time, pour the mixed material onto the slip resistant broadcast layer and spread evenly using a squeegee at the required consumption rate to completely encapsulate the sand. Then using a short-piled roller, back roller in two directions at right angles to each other. A seamless finish can be achieved if a ‘wet’ edge is maintained during application.

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