Hychem SL50 — Impact resistant self-levelling epoxy topping

Product description

HYCHEM SL50 is a 100% solids, flexible self-levelling epoxy flooring system. It is impervious and designed to provide a smooth seamless floor. It is recommended for use as a heavy duty floor topping (2 – 4 mm) system for protection of concrete and steel floors. It is particularly useful where some movement or flexing of the substrate is expected or where a softer feel is desired.

Features and benefits

  • Chemical resistant – resists dilute acids, alkalis and commercial cleaning agents.
  • Abrasion / impact resistant – hard wearing and durable.
  • Highly flowable – will self-level to a flat finish.
  • Smooth/Glossy finish – easy to clean and maintain.
  • Excellent adhesion to concrete and most other coating or topping systems.
  • Low / no odour – does not taint food.
  • Non-flammable – no fire hazard.

Application guidelines

Summary from the data sheet — follow the PDF on site.

Surface preparation
  • Concrete substrate shall be firm, clean and dry with a compressive strength of 25 MPa and surface tensile strength of 1.5 MPa minimum.
  • New concrete must be allowed to cure for a minimum of 28 days.
  • Repair imperfections (holes and cracks) with an epoxy patching compound such as Hychem GP where necessary.
  • Remove surface laitance, contaminants, coating, curing compound and all weak and loose materials.
  • Prepare concrete surface by Diamond Grinding, Scarifying or Captive Shot Blasting to provide the appropriate surface profile for optimum mechanical keying.
Priming
  • The prepared surface must be primed with Hychem GP at a rate of 4 to 6 sqm/litre to ensure that no air holes remain. Highly porous surface should be doubled primed.
  • Allow Hychem GP to cure for 12 to 16 hours but not more than 24 hours otherwise re-priming will be required.
Mixing
  • Mix Hychem SL50 liquid components (Resin & Hardener ) together using a helical mixer at a speed of 500 rpm until the mix becomes homogeneous (2 to 3 minutes should be sufficient)
  • Product must be mixed slowly to avoid aerating.
Applying
  • Pour the wet mix on the floor. Spread over the floor area using a pin rake or notched trowel set at a pre-determined thickness.
  • Ensure to maintain continuity of wet material between pours.
  • Roll the surface with a spike roller to remove entrapped air.
  • Allow to cure for 24 hours before exposing to foot traffic.
Clean up

Xylene can be used for cleaning tools and equipment before the mixed compound begins to harden.
