Heydi K11: 60lb Kit Cement Crystalline Waterproofing

Surface Preparation: New concrete and masonry must be cured a minimum of 7 days. The surface must be structurally sound, clean and free of dirt, oil and other contaminants including curing compounds, form release agents, old coatings, paint and efflorescence. All concrete laitance must also be removed. Provide an absorptive surface on all substrates including precast and formed concrete. The surface must have an open capillary system for adhesion and for optimum crystalline growth. Remove form marks and other protrusions. Concrete honeycombs, cavities, joints, cracks, voids, tie holes and other defects must be opened and routed to sound material. Follow the recommended methods for repairing defects as suggested below. No active water leaks should be present at the time of application of HEY’DI K-11. Use the HEY’DI POWDER X SYSTEM to seal active leaks.

Mixing (25 lb. Contractor Kit): The included gallon of HEY’DI SB BONDING AGENT is ready to use, and does not require dilution with water. Pour approximately 0.50 gal (1.9 L) of the included mixing liquid into a clean container and begin slow speed power mixing. Slowly add HEY’DI K-11. Gradually add more mixing liquid to bring the mixture to the consistency of a completely blended slurry. Mixing 25 lb (11.4 kg) of HEY’DI K-11 will require 0.75 to 1 gal (2.84 to 3.80 L) of mixing liquid. When mixing is completed, do not add additional mixing liquid and do not retemper the mix by adding water.

Mixing (50 lb Bags): Positive Side Waterproofing: Blend a 1:5 ratio of HEY’DI SB BONDING AGENT with potable water to make the “mixing liquid”. Negative Side Waterproofing, blend a 1:3 ratio of HEY’DI SB BONDING AGENT with potable water to make the “mixing liquid”. To mix a 50 lb (22.7 kg) bag of HEY’DI K-11, pour approximately one gal (3.8 L) of mixing liquid into a clean container and begin slow speed power mixing. Slowly add HEY’DI K-11. Gradually add more mixing liquid to bring the mixture to the consistency of a completely blended slurry. Mixing 50 lb (22.7 kg) of HEY’DI K-11 will require a 11⁄2 to 2 gal (5.68 to 7.57 L) of mixing liquid. When mixing is completed, do not retemper the mix by adding additional mixing liquid.
