NEW! Weco® W800+ Durokryl™ is an ultra-premium additive made of latex and non-redispersible synthetic rubber, designed for Portland cement mortars, concrete applications, and grouts. Weco® W800+ Durokryl™ significantly improves workability, adhesion, tensile strength, and flexural strength. It is also ideal as a bonding primer for promoting adhesion to existing concrete surfaces. Meets or exceeds ASTM C-1059 Type II, ASTM C-932, and ANSI A118.4 standards.
PRODUCT USES:
Weco® W800+ Durokryl™ can be used to modify thin-set mortars, grouts, Portland cement mortars, and concrete, enhancing bond strength and flexibility, reducing water permeability, increasing chemical and compressive resistance, and overall durability. It is excellent for bonding new cement mortars or concrete to existing concrete in applications like repairs, toppings, self-leveling mortars, concrete coatings, rendering, and other masonry uses.
MIXING:
Weco® W800+ Durokryl™ is a concentrated product and may be diluted with water. Recommended mix ratios: 1 part Weco® W800+ Durokryl™ to 1 part water (1:1) for cement grouts, 1 part Weco® W800+ Durokryl™ to 3 parts water (1:3) for mortar mixes, and 1 part Weco® W800+ Durokryl™ to 4 parts water (1:4) for toppings. Do not dilute when using for concrete bonding or as a primer. For best results, add the dry cement or mortar mix to the diluted Weco® W800+ Durokryl™ liquid and mix using a low-speed electric mixer. Take care to avoid entraining air into the mixture.
CURING:
Protect from light foot traffic for at least 24 hours and from heavy traffic for at least 72 hours, depending on temperature and humidity. Keep the application area moist to prevent surface cracking from premature drying.
