ACTICHEM Defender WB Water Based Water Repellant 2.5 Litre AP179025
Defender WB
Premium protection against water ingress to masonry & concrete
Product Description
Defender WB is a premium water-based penetrating sealer formulated for concrete, masonry, cement, clay products, and sandstone. It uses high-performance impregnators to deliver deep, long-lasting protection against water and water-borne contaminants while preserving the surface’s natural appearance.
Defender WB solves the challenge of protecting porous construction materials from water damage, efflorescence, and spalling. Its vapour-permeable formulation reduces biological growth like mould and mildew, resists environmental stressors including salt ion ingress, and enhances surface durability. Ideal for outdoor and indoor use on masonry and engineered concrete, it provides up to 5 years of protection.

Additional Information
Benefits
Premium Protection: Provides exceptional defense against water-borne contaminants, chloride ions, and biological growth.
Long-Term Benefits: Offers long-lasting repellency that helps protect against efflorescence, spalling (freeze-thaw damage), corrosion of reinforcing bars, salt ion ingress, weathering, mould, and staining.
Natural Look: Maintains the original appearance of treated surfaces without discoloration or alteration of the natural look.
UV Stable: Suitable for both indoor and outdoor use, remaining effective under UV exposure.
Vapour Permeable: Allows moisture to escape, preventing trapping of water vapour and ensuring the health of the substrate.

Mortar, grout and masonry
Expected Wear:
Defender WB will provide premium protection for up to 5 years. However application methods, weather conditions, traffic, harsh cleaning methods and stone type will affect wear. Avoid use of solvents, strong acids and strong alkalis for extended sealer life.
Cleaning with Actichem Proneutro is advised.
It is recommended that the sealer be re-applied every 3 years where harsh conditions exist.
How to use
Read and understand the SDS before use.
Always pre-test in an inconspicuous location for substrate sensitivity to chemicals.
Preparation:
New installations must be fully cured before application of Intense (Min 48 hours) Some concrete installations may take up to 7 days to cure. Confirm with the structural engineer). Existing stone, tile and grout must be totally clean, dry and chemical free.
Existing stone, tile and grout must be totally clean, dry and chemical free.
Coverage:
Coverage can vary dramatically depending on the degree of porosity, but is normally 5 to 15 m2 / Lt per coat for open structure, highly porous substrates and 20 to 30 m2 / Lt per coat for dense, less porous substrates. The coverage for the 2nd and 3rd coats is dramatically greater.

Ready to use
Application
Apply 1 to 3 coats of Defender WB by generously saturating the surface using a polish applicator, roller or sprayer.
Using a squeegee or/and absorbent towelling or applicator, wipe off any excess sealer remaining on the surface after 10 minutes of application. Do not allow surface to dry during this time.
Allow 20 minutes in between coats. Apply subsequent coat whilst previous coat is still wet.
Keep traffic off for 6 hours. Keep dry for 24 hours. Achieves a full cure in 24-48 hours.
