Kerakoll Proflow MVS Instructions

Preparation of substrates

The substrate must comply with current British standards and industry regulations. In general, substrates must be free of dust, oil and grease, free from any moisture rising, with no loose, flaky or imperfectly anchored parts such as residues of cement, lime, paint coatings and adhesives, which must be completely removed. The substrate must be stable, without cracks and have a functioing structural DPM within the subfloor. If no structural DPM is present, a surface epoxy DPM must be applied. Kerakoll Proflow Smooth can be used to pre-smooth the floor at 95% RH prior to installing a surface epoxy DPM to perform as a structural DPM.

In particular, substrates must be treated with a suitable primer as shown in the table:

Usage Instructions

Preparation
Pour the pre-measured 5 l bottle of Kerakoll Proflow MVS liquid into a clean container; then pour in a bag of Proflow MVS, while shaking. Mix with a mechanical mixer until the mixture is smooth, lump-free and self-smoothing. Larger quantities of Proflow MVS may be prepared in suitable mixers. After the first mixing, it is advisable to leave the mixture to rest for approx. 2 minutes and then mix again briefly. Proflow MVS features a high degree of self-levelling capacity. Adding extra water does not improve its workability, and may cause shrinkage in the plastic phase of drying and result in less effective final performance with a reduction in surface hardness, surface finish, compressive strength and adhesion to the substrate.

Application
Proflow MVS is generally applied with a flooring trowel, cam rake or pin level. The use of an aeration or spike roller can be used but is not required to further improve the surface finish of Proflow Smooth, but will work to remove entrapped air from the mixture. If an additional application of Kerakoll Proflow MVS is required once the initial application has been completed, the first installation layer must first be hardened and ready to accept foot traffic and additional application, this is generally after 4 hours. The initial layer of Proflow MVS must be primed with a neat coat of Prime+ Grip prior to subsequent applications. In the case of low temperatures and high humidity it is advisable to keep the environment ventilated during application and during the hours immediately following application, in order to avoid the formation of condensation on the surface of the self-levelling gel during the setting phase.

Cleaning
Residual traces of Proflow MVS can be removed from tools using water before the product hardens.

Notes

Joints: perimeter expansion must be allow for in the application of self levelling compounds. Perimiter expansion edging strip must be installed along the whole perimeter of the room, on the walls and on any other vertical elements protruding from the supporting layer. Large and continuous surface areas need to be broken into bays as soon as they can withstand foot traffic so to create areas < 100 m2 with 10 m maximum individual size. All movement or expansion joints located in the substrate must be respected.

Hardwood floors: for subsequent laying of hardwood floors, create a smooth finish with thickness ≥ 3 mm.

NB Limitations

• Product for professional use
• abide by any British standards and industry regulations
• do not use Proflow MVS to correct substrate irregularities greater than 12 mm
• do not add other binders, additives or pigments to the mixture
• low temperatures lengthen drying times and may saturate the environment with negative consequences on the surface consistency of the self-levelling gel
• an excessive quantity of water will reduce strength and the drying time
• respect any movement or expansion joints present in the substrate
• if necessary, ask for the safety data sheet
• for unstable wooden types, particular substrates and for any other issues, contact the Kerakoll Worldwide Global Service.
