As well as hardening and strengthening concrete, it can be used as a primer to reduce the porosity of highly absorbent surfaces (such as sand and cement screeds), and can be used on brick, blockwork, plaster walls and block paving to strengthen and bind the sandy joints together.

Areas of use:

  • Warehouses;
  • Production areas;
  • Machine shops;
  • Storage Rooms.


A clear, water-based, easy to use sealer containing a micronised acrylic which penetrates deep into porous surfaces to strengthen and bind together weak, poor quality concrete (and similar surfaces) to leave a dust-free hardened surface.

Features and benefits:

  • Clear, penetrating dustproofer and hardener.
  • ‘Permanent’ dustproofing treatment since it penetrates and becomes part of the substrate – no surface film to damage or wear away.
  • Strengthens and binds weak dusty concrete and sand and cement screeds.
  • One application eliminates dust and reduces staining.
  • Quick and easy to apply – just pour on and sweep with a soft broom.
  • Virtually solvent free and odourless.
  • Breathable.
  • A+ VOC emissions rating with a very low VOC content.
