Application Method
Preparation
Ensure substrates are clean and sound. Remove all existing coatings, cement laitance, unsound, honeycombing and spalling concrete by suitable mechanical means. All dust, dirt and loose materials must be thoroughly removed by brush, broom or vacuum from the areas to be coated. Grind off all ridges & sharp projections. Scrap off all flaking material & remove oils, grease and other adhesion inhibiting substances. Rinse the substrate and while its damp, apply Terraseal.
Application
Mixing Ratios and Process
15kg powder: 5kg resin. Add powder to resin and use a high speed mixer with spiral head attachment to achieve a lump free homogeneous mix.
Tools may be cleaned with water, ensure this is done within one hour of mixing of materials.
It is recommended to mix full kits only. Place the resin in a clean mixing vessel then slowly add the powder while mixing for at least 3 minutes with a slow speed mixer (200-600 rpm) until the mix is completely homogeneous and lump free.
Ensure the blade remains below the surface of the mixture to minimize the entrapment of air and that no powder remains unmixed on the sides and in the corners of the mixing vessel.
Leave to stand for at least 5 minutes to release any entrapped air. Mix again for 30 seconds before application. During application ensure occasional stirring to keep the aggregates in suspension.
Notes: Do not add water to adjust or re-temper the mix. When bulk mixing; only mix required kits of Terraseal that can be used within its pot life.
Application procedure
- Ensure all dirt and foreign matter are cleaned off the areas to be coated.
- Remove any ridges or form oil. Dusty or flaking surfaces must be cleaned thoroughly, then primed with Penetrating Primer Clear or Terrabond A
(diluted 1:3 with water).
- Apply Terraseal onto the water saturated substrate in a minimum of 2 coats, each at right angles to the other; to achieve a total thickness of 1.0-1.5 mm.
- Do not re-temper mixed Terraseal with additional water.
- For spray application please consult your local Terraco Technical Department. If spraying, add only enough water to bring product to the correct
sprayable consistency.
- During brush application, ensure that the Terraseal slurry mix is pressed firmly onto the substrate to ensure maximum adhesion and that all pinholes,
cracks, honeycombing etc. are thoroughly filled and sealed.
