Other colours on request.
The colour of the Sikafloor®-330 has to be approximately adjusted to the colour of the Sikafloor®-305 W seal / top coat.
Applied colours selected from colour charts will be approximate.
For colour matching: Apply colour sample and confirm selected colour under real lighting conditions.
When product is exposed to direct sunlight, there may be some discolouration and colour variation, this has no influence on the function and performance of the floor finish.

EQUIPMENT
Select the most appropriate equipment required for the project:
Substrate preparation
- Abrasive blasting cleaning equipment
- Planing machine
- Scarifying machine
- High pressure water blasting equipment
For other types of preparation equipment, contact Sika Technical Services
Mixing
- Electric single paddle mixer (300–400 rpm) with spiral paddle
- Scraper
- Clean mixing containers
Application
- Mixed material carrier
- Pin leveller
- Trowels
- Spiked roller
MIXING
Prior to mixing all parts, mix separately Part A (resin) using the electric mixing 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 2.0 minutes until a uniformly coloured mix has been achieved. To ensure thorough mixing pour materials into a clean container and mix again for at least 1.0 minute 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 straight edge trowel or spatula at least once to ensure complete mixing. Mix full units only. Mixing time for A+B = ~3.0 minutes.
APPLICATION
Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
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.
Pour mixed Sikafloor®-330 onto the 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. A seamless finish can be achieved if a ‘wet’ edge is maintained during application. When Sikafloor®-330 is “tack-free”, apply the Sikafloor®-305 W seal coat.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened material can only be removed mechanically.
CLEANING
