Render Mix

Ready-to-use thick plastering for interior and exterior walls


A thick plaster you mix with water and apply straight onto concrete — it corrects level irregularities and fills bubbles, pinholes, and defects up to 15 mm deep.

Use it for

  • Correcting level irregularities in concrete walls
  • Filling bubbles, pinholes, and surface defects up to 15 mm
  • Rough plastering ahead of skim coat and paint
  • Interior and exterior surfaces

Why this one

  • No more tedious mixing
    Ready to use — just add water. Cuts time, cost, and hassle on site
  • Grips rough concrete
    Excellent adhesion to rough substrates, based on Portland cement and silica sand
  • Fills to 15 mm in one pass
    Deep enough for bubbles, pinholes, and honeycombing that skim coat cannot reach
  • Resists cracking
    Formulated to resist the formation of cracks as it cures
  • Does not sag
    Holds its position on vertical work, so thick sections stay where you put them
  • Fast setting
    Move on to the next stage sooner
