AREA OF USE :
Terraseal is suitable for waterproofing concrete and masonry substrates prior to application of Terraco Exterior Insulation Finishing System (EIFS) or any nonload bearing assemblies like curtain wall systems. Terraseal is also suitable for waterproofing of cement fiber boards.
PREPARATION OF SURFACE :
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 and sharp projections. Scrap off all flaking material and remove oils, grease and other adhesion inhibiting substances. Rinse the substrate and while its damp, apply Terraseal. For highly absorbent substrates, liberal application of Terrabond-A (1:5 parts diluted with water) is recommended)
MIXING :
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 minimise 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.
HEALTH & SAFETY :
Avoid prolonged contact with eyes and skin. Rinse with clean water. Seek medical treatment immediately. For detailed information refer to relevant material safety data sheet.
PACKAGING & STORAGE :
