Methods of Application: By spraying, rolling or brushing.


Tools Needed: CHEM-SEAL 14-WB can be applied using one or more of the following:

  • Low pressure or airless sprayer
  • Good quality paint roller
  • Good quality paint brush


Surface Preparation: The substrate must be sound, dry, clean and free from any contaminant like dust, dirt, mildew, algae, curing compounds, form release, sealers, oils, grease, etc.


Dirt and dust can be removed by sweeping and low-pressure washer. Areas contaminated with mildew, algae, oils and grease can be cleaned using a high-pressure washer and a biodegradable concrete cleaner like CHEM-CRETE CONCLEAN CCC060.


Cleaning of substrates treated with curing compounds, form release and sealers might be achieved by means of mechanical methods, such as shot blasting, grinding, wire brushing, and high-pressure washer.


Do not use acid etching, solvents or adhesive removers to clean substrates prior to application of CHEM-SEAL 14-WB.


Mixing: CHEM-SEAL 14-WB is ready to use; however, it is recommended to be stirred before use. Take the required quantity into the paint tray or the sprayer for application and tightly close the product’s container.


Coverage: 200 ft2/Gallon (4.91 m2/liter).  Coverage depends on the porosity of the substrate and the final gloss required.


Compatibility: CHEM-SEAL 14-WB can be applied over virtually all sound substrates such as old masonry, old concrete, new masonry, new concrete, brick, terrazzo, unglazed tiles, asphalt, natural stone, etc.


CHEM-SEAL 14-WB can also be applied over materials that may degrade under UV rays to protect against such degradation. Example of these materials is polyurethane foams.



  • Minimum substrate temperature: 40°F (4.4°C).
  • Application on wet or water logged substrates is not recommended.


Cleaning: tools, equipment, spray unit, etc. can be cleaned immediately using water only.


Store the product in cool dry area. Recommended storage temperature is from 40°F to 95°F (+4.4°C to +35°C). Don’t expose container to direct sunlight. PROTECT FROM FREEZING. Keep container closed when not in use. Shelf life is minimum 1 year in its original unopened container.


As all chemical products, adequate care must be taken. Avoid direct contact with food, eyes, skin, and mouth. KEEP AWAY FROM CHILDREN AND ANIMALS.


Breathing mask, goggles, and gloves should be worn during the application of CHEM-SEAL 14-WB. Skin contamination should be cleaned with plenty of water. If splashed into the eyes, it should be washed with a plenty of water using an eye-cup Optrex or Isogutt solution, then consult your doctor
