MASTERSEAL is a tough methacrylate sealer providing resistance to water, mildew, and delamination from the heat of vehicle tyres. It provides stain resistance and colour enhancement making this product a superior sealer to protect and preserve exposed and decorative concrete.

MASTERSEAL provides a UV-stable, non-yellowing, satin appearance while slightly darkening the substrate. The surface must be clean, and free of grease, oil, dirt, wax, or other foreign matter.


    • If the surface has efflorescence, staining or purged contamination, this will be visible unless removed prior to application.
      • Prepare all surfaces with a water blast or abrasion to provide a sound, clean surface.
      • Make sure that the bond to any previously applied stain or sealer is secure by applying sealer to a small area and checking for possible lifting before proceeding.
      • On newly installed tile or brick, allow grout joints to dry thoroughly before applying.
      • New concrete surfaces must be visually dry before applying MASTERSEAL.
      • MASTERSEAL can be applied as soon as 24 hours after the concrete has been poured, providing the surface is visually dry.
      • Rain, fog, or excessive cold will affect the sealer prior to drying.
      • For best results on vehicular trafficked surfaces, any previous sealers or coatings must be removed from the base concrete.
      • Stir contents thoroughly before and during application to ensure full suspension of slip-resistant additives.
      • After thorough preparation of surfaces, MASTERSEAL can be applied by brush or roller.
      • When applying MASTERSEAL a “wet edge” must be maintained, with application finishing on a joint/saw cut/edge.
      • In warmer conditions or on large floor areas use MASTERSEAL Retarder to increase the drying time of the sealer – to max. ratio of 4 parts sealer to 1 part retarder (e.g., 4L in 20L pail).
      • MASTERSEAL has an average total practical coverage rate of at least3.5 m2per litre depending on substrate porosity, in a minimum of two coats.
      • More applications may be necessary, depending on the porosity of the surface being sealed.
      • For best results, MASTERSEAL should be applied when the surface temperature is between 10-29ºC.
      • It is best to allow up to 24 hours between coats for proper curing, depending on temperature. Curing times can be significantly reduced, depending on the surrounding circumstances.
      • It is recommended that foot traffic remains off the finished sealed surface for 24 hours. For heavy traffic, allow 72 hours for curing.


      Obtain special instructions before use. Do not handle until all safety precautions have been read and understood.

      Keep away from heat, hot surfaces, sparks, open flames, and other ignition sources. No smoking. Keep the container tightly closed. Use explosion-proof electrical, ventilating, and lighting equipment. Use non-sparking tools. Take action to prevent static discharges.

      Avoid breathing fumes, mists, vapour, or spray. Wash hands thoroughly after handling.

      Use only outdoors or in a well-ventilated area.

      Wear protective gloves, protective clothing, eye, and face protection.

      MASTERSEAL should not be applied when the surface temperature is below 10 ºC or above 29 ºC.

      Store in a well-ventilated place. Keep cool. Store locked up.

      Dispose of contents and containers in accordance with local, regional, national, and international regulations.

      In case of fire: Use foam, dry chemicals, or CO2 to extinguish.


      Stubborn Soiling: Rubber marks, chewing gum, and stubborn soiling or grease can be treated with a DLX citrus degreaser. Spray DLX undiluted onto the soiling and allow it to soak in for 5 minutes. Scrape/wipe away the soiling and clean as per regular cleaning.

      Maintenance: Clean surface with mechanical scrubber using 3M red pads. Buff with a standard swing buffing machine and buffing pad to remove scuff marks and enhance the surface.

      High Traffic Areas: Recommend bi-monthly.

      Medium Traffic Areas: Recommend 6 monthly.

      Assess wear after 5 years to ascertain if re-coating is required.


      Store in a dry location within a temperature range between 4-38ºC.

      Surplus products must be disposed of in accordance with local regulations. Clean containers can be recycled. (type2 HDPE)
