SL200 Self Levelling Concrete

Application

  • Corrects uneven or wavy concrete or wood finishes.
  • Levels and repairs uneven surfaces.
  • Used as a chemical/ acid resistant barrier for vulnerable materials.

Description

An acid resistant, low permeability, medium density flowable concrete for use over wood, masonry, or cementitious elements as a structural leveling layer. SL200 contains no Portland Cement and none of the weaknesses including no bleed water, reduced freezing temperature of 14°F. SL200 is exothermic for the first approximate 120 seconds, and then produces an endothermic chemical cure.


For flat and level floor construction, final placed concrete elevations can be left 1/8” to ¼” below intended final

elevation. SL200 is placed as the final surfacing thereby removing the need for extensive finishing efforts to achieve floor flatness and levelness requirements.


Preparations:

Prepare the surface of wood by removing any dirt, debris, or incompatible coatings.


Features and benefits:

  • Low shrinkage and low thermal coefficients.
  • No VOCs.
  • Cures quickly in warm/hot weather allowing rapid completion of projects.
  • Can be polished after four days of warm curing.
  • Shrinkage compensators reduce/ remove cracking.
  • Elevated alkalinity removes mould and bacterial growth.
  • Bonds to wood, concrete, masonry and just about everything except plastic or galvanizing.
  • Resistant to all organic and inorganic acids and concentrations except for hydrofluoric.
  • Acts as a water sealant.
  • Can be coloured.
  • Green Technology containing absolutely no Portland Cement.
