Euclid Chemstop WB Regular Water Repellent, 5 gallon pail
Euclid Chemstop WB Regular is a water-based silane/siloxane penetrating water repellent. It is used on dense precast and poured-in-place concrete, interior or exterior, on horizontal and vertical surfaces. The formula is breathable, helps cut water and salt uptake, and air and surface temperature should be at least 45 F and rising, not above 90 F, and new concrete should be at least 7 days old.
Key Features

Frequently Asked Questions
Where is Euclid Chemstop WB Regular used?
Euclid Chemstop WB Regular is used on dense surfaces such as precast and poured-in-place concrete, including precast structures. It is placed on horizontal or vertical work, interior or exterior.
What SS-W-110C water-absorption reduction does Euclid Chemstop WB Regular show?
Typical laboratory reduction in water absorption is 90.5% (SS-W-110C). Active content is 6% by weight. Expect reasonable variation under field conditions.
What coverage does Euclid Chemstop WB Regular have on dense surfaces?
Approximate coverage is 80 to 150 ft²/gal for one coat on dense surfaces. Rates are for estimating only.
How soon can Euclid Chemstop WB Regular be applied to new concrete?
New concrete should be at least 7 days old before Euclid Chemstop WB Regular is applied. Longer cure generally improves sealer performance. The substrate should be clean and dry.
What rain hold-off does Euclid Chemstop WB Regular need?
Do not apply Euclid Chemstop WB Regular if rain is expected within 12 hours. Water-repellency properties develop 24 hours to 5 days after application.
What flash point does Euclid Chemstop WB Regular show?
Typical laboratory flash point is greater than 200 F. VOC is less than 50 g/L. Expect reasonable variation under field conditions.
