There are different sealants for different applications. We have Single Pack Sealants and Twin Pack Sealants.

Single Pack Sealant

National Crete Single Pack Sealant is the most convenient multi-purpose cementitious Sealant on the market.

It is a penetrating sealant which is primarily used as a very durable protective coating on all National Crete Wall Plaster applications.

It is 100% water repellent, strengthens poor quality cementitious Substrates by penetrating into the porous material, preventing the material from becoming brittle and cracking apart.

It is ideal for outdoor cementitious garden furniture, pots, paving and facebrick. It has a very durable smooth Satin finish.

Applying Single Pack Sealer:

  • Always remember to de-fluff a new roller before use.
  • Thoroughly shake and stir the 5L container, apply 1 coat of Single Pack Sealer with a 225 mm Hamilton’s Polypile roller and cut in with a 50 mm paint brush.
  • Use a criss-cross action of application to achieve a full & uniform coverage.
  • Always keep a wet edge to prevent unsightly lap marks.
  • The coat of Single Pack should be thinnish, not too liberal, but have a uniform coverage.
  • If more than 1 coat is required:
      • Two (2) thin coats are always better than one (1) thick coat.
      • Leave to dry for approximately (4) hours.
      • Apply the second coat exactly the same way as the first coat.
  • All equipment and utensils must be cleaned with thinners

Twin Pack Sealants

This is an industrial polyurethane coating. It is a protective coating for high durability, anti-abrasion and high impact resistance.

Mixing & Applying Twin Pack Sealer:

  • Allow ±1-2 hour drying time for the applied Colour Retainer or leave until the next day, as the drying time will vary from interior to exterior and daily temperature.
  • Apply two coats Twin Pack Sealer whilst wearing socks only.
  • Thoroughly shake both Part A and Part B of the Twin Pack Sealer individually whilst still in the containers.
  • Pour together the full contents of both Part A and Part B and thoroughly shake for a minute or two.
  • NEVER pour only PART OF THE CONTENTS of the individual containers together, as this will alter the formula and will cause negative reactions.
  • Always remember to de-fluff a new roller before use.
  • Apply 1 coat of the mixed Twin Pack Sealer to the floor that has been coated with Colour Retainer, using a 225 mm Hamilton’s Polypile roller and cut in with a 50 mm paint brush.
  • Use a criss-cross action of application to achieve a full & uniform coverage.
  • Always keep a wet edge to prevent unsightly lap marks.
  • Two (2) thin coats are always better than one (1) thick coat.
  • Leave to dry for 12 hours (approximately (4) four to (12) twelve hours.
  • Apply the second coat exactly the same way as the first coat.
  • NB: The mixed Twin Pack product cannot be stored for longer than 4 hours before use.
  • The spread rate is 8 m²/litre.
