Sikafloor® TC 242

(former MSeal TC 242)

TOTAL SOLIDS, 2 PART, GLOSSY, AROMATIC PU COATING FOR TRAFFIC DECK APPLICATION

Sikafloor® TC 242 is a two-component elastomeric, pigmented, polyurethane (PU) coating designed for application in trafficked areas. 
Sikafloor® TC 242 aesthetically enhances and protect parking garage floors due to its pigmented, glossy and bright finish, minimum dirt pick-up and ease of cleaning properties. Its hard-elastic surface reduces slippage and the squeaking noise from tires. When combined with its excellent chemical and abrasion resistance, Sikafloor® TC 242 is the ideal coating for car park decks.  Suitable for use in hot and tropical climatic conditions.

  • Excellent impact and abrasion resistance
  • Glossy finish aesthetically enhancing car park
  • Elastomeric
  • Good chemical and oil resistance
  • Minimum dirt pick-up and no tire mark retention
  • Ease of cleaning
  • Reduced noise due to tire movement
  • Long service life
  • Profiled finish for slip resistance

Consumption

Consumption

From 0.65 kg/m² per coat. Please refer to relevant system data sheet and method statements for build-ups and coverage rates.

This figure is theoretical and does not allow for any additional material required due to surface porosity, surface profile, variations in level or wastage, etc.
Application steps

APPLICATION INSTRUCTIONS

For full application requirements please refer to relevant method statement.

SUBSTRATE QUALITY

Fully cured, with min. compressive strength of 25 N/mm2. Pull-off strength shall not be less than 1.5 N/mm2.

If in doubt apply a test area first.

SUBSTRATE PREPARATION

The surface must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by vacuum.

Suitable preparation includes light grit blasting, surface grinding etc. Surface defects should be repaired using Sikafloor®-2200, Sikafloor®-2200 ADH or other suitable repair compounds from the e.g. Sikadur® or SikaEmaco® range.

MIXING

Mix the Part A and Part B components of the Sikafloor® TC 242 together using a slow speed (400 rpm) drill with a spiral mixing head. Work the mixer round the mixing pail to ensure it scrapes the side and bottom of the pail. Pour the part mixed material into a clean pail and remix for a further 30 seconds.

APPLICATION

Apply by roller or squeegee to the primed tack free surface. Apply at a minimum recommended rate per coat, depending on the system build-up. Sikafloor® TC 242 can be applied as a single intermediate coat, or as a multi coat sandwich system incorporating aggregates to give a slip resistant finish. When applying as a top coat or part of a multi coat system, do not exceed the maximum overcoating times of the previous coating. 

CLEANING OF EQUIPMENT

Clean all tools and application equipment with suitable thinner (Xylene / MEK / Acetone) immediately after use. Hardened and/or cured
material can only be removed mechanically.
