VDF FLOORING
Vacuum dewatered flooring is a construction technique that uses a vacuum to remove excess water and air during the pouring and curing of concrete. It helps in creating strong, durable and stable floors that are resistant to cracks and other types of damage.
The process typically involves pouring a layer of concrete over a prepared base before using a vacuum pump to remove excess water and air from the mix. This can be done manually using a portable vacuum pump or automatically using a specially designed machine for this purpose. The resulting floor is generally smooth, level and ready for use when fully cured.
VDF Flooring The Process
Vacuum dewatered flooring, also known as "dry shake" floor hardener, is a improve the surface density and wear resistance of concrete floors. This involves applying a dry, powdered hardener to a surface of freshly placed and finished concrete before using a vacuum to remove excess material and water from the surface.
Here's the step-by-step process for installing a vacuum-dewater floor
- Prepare the concrete surface: Make sure the concrete is placed correctly and prepared with a smooth, even surface. Remove excess water from the surface using a squeegee or a broom.
- Mix the floor hardener. Follow the manufacturer's directions for mixing the floor hardener. This usually involves adding water to the dry powder and stirring it to form a slurry.
- Apply floor hardener. Using a shovel or spreader, spread the floor hardener evenly over the concrete surface.
- Vibrate the surface: Use a vibrating screw or hand-held vibrator to compact the floor hardener and ensure good coverage and penetration into the concrete.
- Vacuum the surface: Use a wet/dry vacuum to remove excess water and hardener from the surface of the concrete.
- Cure the surface: Allow the concrete to cure according to the manufacturer's recommendations before walking on the concrete or using it for any purpose. This usually involves keeping the surface moist and covered for a period of time.
- Finish the Surface: After the concrete has cured, you can proceed with any desired surface finishing techniques, such as grinding, polishing or applying a sealer. .
