Euclid Chemstop WB Heavy Duty Water Repellent, 5 gallon pail
Euclid Chemstop WB Heavy Duty is a water-based silane/siloxane penetrating water repellent. It is used on lightweight concrete, concrete block, and other porous masonry, on horizontal and vertical work, interior or exterior. The surface stays breathable after it dries, chloride absorption is reduced, and air and surface temperature should be at least 45 F and rising, not above 90 F.
Key Features
- Water-based silane/siloxane for porous masonry
- 10% active content by weight
- Breathable; helps cut water and chloride uptake
- Dries clear with no gloss and no texture change
- Horizontal or vertical, interior or exterior
- Water repellency develops over 24 hours to 5 days
Applications
- Lightweight concrete, concrete block, and mortar joints.
- Brick, natural stone, and other porous masonry.
- Horizontal or vertical surfaces, interior or exterior.

Frequently Asked Questions
Where is Euclid Chemstop WB Heavy Duty used?
Euclid Chemstop WB Heavy Duty is used on porous work such as lightweight concrete, concrete block, mortar joints, brick, and natural stone. It is placed on horizontal or vertical surfaces, interior or exterior.
What active content does Euclid Chemstop WB Heavy Duty have?
Typical laboratory active content is 10% by weight. Depth of penetration is 3/8 in, substrate dependent. Expect reasonable variation under field conditions.
How soon does Euclid Chemstop WB Heavy Duty develop water repellency?
Water-repellency properties develop 24 hours to 5 days after application. Do not apply Euclid Chemstop WB Heavy Duty if rain is expected within 12 hours.
What application temperature does Euclid Chemstop WB Heavy Duty need?
Air and surface temperature should be at least 45 F and rising. Application above 90 F is not recommended. New concrete should be at least 7 days old.
What ASTM E514 water-leakage reduction does Euclid Chemstop WB Heavy Duty show?
Typical laboratory reduction in water leakage is 100% on brick and greater than 91% on mortar block (ASTM E514). Water-absorption reduction is 92.3% (SS-W-110C). Expect reasonable variation under field conditions.
What coverage does Euclid Chemstop WB Heavy Duty have on porous surfaces?
Approximate coverage is 40 to 60 ft²/gal on the first coat and 60 to 100 ft²/gal on the second coat, on porous surfaces. Rates are for estimating only.
