Prepare

  • General: Surfaces should be as dry as possible as moisture can affect the penetration of the sealer and possibly lead to a white blooming effect.
  • On concrete, masonry and sand/cement screeds: Often a good sweep is all you need to prepare the surface. If the concrete is new, it must be left for 2 weeks. Any laitance (a dusty residue of cement particles) can be removed with a good stiff brush.

Apply

  • One application is usually enough. Simply keep applying it until the concrete cannot absorb any more of the liquid. Avoid letting puddles dry on the surface by sweeping any unabsorbed liquid onto adjacent areas with a soft broom.
