High performance surface sealer, which has been formulated to react with hydrated cement both at the surface and at a depth of 15 mm.

Features and benefits:

  • Provides concrete with a durable, long-lasting surface.
  • Improves resistance to surface water absorption/ lime efflorescence.
  • Quick and easy to apply.
  • The silicone resin component cures to form water repellent properties.
  • Water-based.
  • Odourless.
  • Reduces the required dusting of old and new concrete.
  • Extends floor life.
  • Reduces the penetration of water/ oil.


Can be applied to new (approximately after 14 days) and old concrete prior to the installation of the PUDLO Cavity Drain System.

Once the first coat is applied, allow the sealer to sit idle for 24 hours between coats. The number of coats required will depend upon the porosity of the concrete and amount of surface dust present.

Not suitable for use as surface preparation prior to painting, and should not be applied in temperatures below 5°C – consult manufacturer for application techniques and product limitations.

Standard product features


  • First coat: 4–6 m².
