Rocket Prime

Description:

Cemix® Rocket Prime is a specially formulated primer designed for enhancing adhesion onto smooth and dense surfaces. Solvent free and non-hazardous. It displays outstanding bonding properties to metals, plastics and glazed surfaces, avoiding the need for solvent etching or hazardous grinding. Ideally suited for the application of Cemix Rubberguard waterproofing membrane coatings, adhesives and mortars to enable reliable adhesion to difficult surfaces.

Typical Application / Uses:

  • For use on non-porous substrates e.g. plastic, glass and steel.
  • Ideal for puddle flanges and pipe penetrations.

Advantages:

  • Ready to use from the container.
  • Provides excellent adhesion to concrete, masonry, plaster, cement fibreboard and most surfaces.
  • Greatly improves tensile, compressive and flexural properties allowing thin section application of concrete, mortar, floor toppings etc.
  • Excellent bond achieved even several hours after application.
  • Is not affected by water in exterior situations. Improves abrasion resistance and durability.
  • Chemical resistance is improved.
  • Improves mobility and performance while reducing shrinkage.
  • Non-toxic (can be used in contact with potable water)

2L, 4L & 15L

Substrate Preparation:

The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent bonding. New concrete should be left with a wood float finish and sufficiently aged for a minimum of 28 days.

Priming over:

  • Metals such as galvanized iron, zincalume stainless steel, copper, brass, and most metals.
  • Vitrified and glazed tiles, natural stone.
  • Dense concrete (steel trowelled) and self leveling compounds
  • Clay brick, precast concrete
  • PVC and rigid plastics
  • Existing acrylic coatings and Cemix® products.
  • For further information contact Cemix® Technical support.

Application:

Stir product well before using. Apply with a long bristle brush or short nap roller Before applying on metals, plastics or glazed surfaces, ensure all solvent or film residues are removed.

Important:

Before commencing the application, adhesion of products to be used (primers, membranes, coatings, adhesives, etc.) should be tested over a typical area of the prepared surface to ensure satisfactory adhesion. Do not apply over sealants such as polyurethanes, silicones, stone top sealers and the like. Only use water based systems over Cemix® Rocket Prime. Not to be used for immersed applications.

Technical Data:
