Sika Metal Dry Spread Floor Hardener

Sika metal dry-spreading floor hardener
Metal dry-spreading floor hardener, commonly known as emery wear-resistant floor, provides a hard and wear-resistant dry-spreading surface layer for the overall floor. Spread and sand onto freshly damp concrete floors to create a smooth, colored, hard-wearing surface.

Construction Notes
◇Dosage
Approximately
◇Base surface requirements
The bottom concrete must be of good quality
The slump must be between
, and minimum water cement must be used Ratio and fully compacted during pouring. The compressive strength needs to be above /
. It is recommended to use
or
plasticizer to ensure the best concrete quality. If fiber is used, during the mixing process It should be dispersed as much as possible.
◇Ambient temperature
Minimum +℃
Maximum +℃
◇Relative air humidity

Pay attention to air drying when the humidity is low. The humidity is high When the height is high, please note that the floating slurry is slower, and the solidification, hardening and electric troweling are all slowed down.
◇Construction tools
Automatic spreader with laser scraper
◇Construction method
Immediately after leveling, spread
the required amount evenly on the concrete at one time.
After manual construction, wait for the water precipitated on the surface to evaporate, and then
spread it twice (the first time /
The second time/
) Spread evenly onto the leveled concrete.
◇Compaction
After the first spread of material is wiped into the floor, immediately spread the second A small amount of
.
makes the surface of the concrete slab harden faster than usual.
◇Cure
Use
Sealing and curing
immediately after finishing.

The above values depend on the concrete reaching the designed service strength and are affected by changes in environmental conditions.
Precautions
The construction of dry dusting powder should not be carried out in places with strong wind or air flow. Due to the natural differences in the base concrete, the dry-spread hardener will give the final surface of the concrete some local color differences. Slip resistance can be enhanced through chemical aging. Dispose of residual material in accordance with local regulations. Completely solidified materials can be treated as domestic waste with the consent of the local responsible authority. For detailed health and safety information and precautionary measures, such as physical, toxicological, ecological and other data, please refer to the safety instructions.
