Freezer Repair Material BioCrete
1. DESCRIPTION
BioCrete SPW-900 is a single component ceramic material for use when the temperature is below -30℃ that
Sets up in approximately 30 minutes and is ready for vehicular traffic in 60 minutes. It bonds strongly
to most concrete, tile, masonry and asphalt surfaces. It can be used equally well indoors or outdoors in a
variety of applications requiring cold temperature usability and develops high early strength enabling
Quick turnaround in demanding environments.

SETTING TIME
· Set Times at 22℃ at 1”(2.54cm) material depth
· Initial set : 20-40 minutes
· Final set : 40-90 minutes
· Working time : 10-20 minutes
· Critical Mix Temperature : 25℃
5. MIXING INSTRUCTIONS
ㆍTo ensure product performance, Do not divide or separate individual units into smaller portions.
Mix entire contents at one time.
· Do not hand mix
· To begin the mixing process, add the proper amount of water.
20kg bag bucket ----- 2.4L(13%±1) of water
· In extremely warm conditions, add up to 1 cup of additional water to 20kg bags
· Ideal water temperature is between 18℃ and 24℃
· If ambient temperatures are above 25℃, mix material for 2 minutes and use cold water at approximately 10℃
· If temperatures are below -20℃ mix until Critical Mix Temperature of 25℃ is reached, but not less than 3 minutes.
(For cold weather applications the mix water should be pre-heated(30~40℃) along with the substrate surface.)
ㆍIt is recommended that a thermal gun or temperature probe be used to ensure that the Critical MIX Temperature has been achieved.
For Aggregate Extension: (Bucket Mixing with Drill & Paddle)
· Use only 5mm ~ 50mm clean washed fractured stone up to 70% maximum by weight.
(For best finishing characteristics, extend by no more 50%)
· Add aggregate to material and water slurry after mixing for 60 seconds.
· See mixing times for NEAT application above.
※ MIXING NOTES:
ㆍBioCrete SPW undergoes an exothermic chemical reaction during blending. Heat, the by-product of the
ㆍReaction, is the best indication that the reaction is complete and that the product is ready to be poured.
ㆍBioCrete SPW-900 has a Critical Mix Temperature of 25℃ which Must Be Reached before placing to Obtain Optimum performance.
6. PACKAGING & SHILF LIFE
· Packaging
packaged in 20kg bag
· Shelf life
Bags – 1years (when stored in original unopened bags)
· Storage
Unused material should be kept in a closed container and protected from moisture and other contaminants.
7. LIMITATIONS
· Will not bond to polymers or epoxy
· Must be mixed with drill and paddle – BioCrete SPW cannot be mixed in grout mixer or rotating drum
Concrete mixers due to rapid set times.
8. APPLICATION & FINISH
· For best results, BioCrete.Co.,Ltd. recommends monolithic placement of repair materials. Maintain a minimum Thickness of 2.54cm if repair material must be x-layered.
· Upon initial set, a broom finish can be applied. Upon final set, the material can be saw-cut, drilled,
Sanded and/or polished.
· Do not re-temper. The addition of water to the surface of the repair will negatively affect the materials
Final properties.
· General loading in 1.0 hour for wheeled traffic and 20 minutes for foot traffic.
· All previously existing joints must be re-established within 1-3 hours of final set.
· Self-curing
· Clean all tools and equipment with water prior to the material reaching final set.
9. SAFETY
· See Material Safety Data Sheet(MSDS)
· This x-document does not purport to address all of the safety concerns, if any, associated with its use.
· Dispose of water and materials in accordance with Cities, Provinces and Local regulations.
· The use of a dust mask, safety goggles and gloves is recommended.
· Keep out of the reach of children.
