Instructions for use

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 functioning DPM within the subfloor. If no DPM is present, a surface epoxy DPM must be applied. Kerakoll Proflow Finish can be used to pre-smooth the floor at 95% RH prior to installing a surface epoxy DPM.

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

Preparation

Pour 4.5 − 5.2 l of clean water into a clean container; then pour in a bag of Kerakoll Proflow Finish, while shaking. Mix with a mechanical mixer until the mixture is smooth, lump-free and self-smoothing. Larger quantities of Proflow Finish 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. Kerakoll Proflow Finish 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

Kerakoll Proflow Finish is generally applied with a flooring trowel, cam rake, pin level or mechanical pump. Application with mechanical pumps allows the installer to very quickly achieve a smooth high-thickness application for large areas. The use of an aeration tool or spike roller is fine/allowed, 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 Proflow Finish 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 3.5 hours. The initial layer of Kerakoll Proflow Finish must be primed with a neat coat of Kerakoll Active Prime Fix 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 smoothing compound during the setting phase.

Cleaning

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

Special notes

Joints: perimeter expansion must be allowed for in the application of self smoothing compounds. Perimeter 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 substrate/subfloor. All movement or expansion joints located in the substrate must be honoured.

Limitations

• Product for professional use
• abide by any British standards and industry regulations
• do not use Proflow Finish to correct substrate irregularities greater than 60 mm
• do not add other binders, additives or pigments to the mixture
• low temperatures and high relative humidity lengthen drying times and may saturate the environment with negative consequences on the surface consistency of the smoothing compound
• an excessive quantity of water will reduce product strength and increase the drying time
• before laying hardwood floors, check the residual moisture content is within the accepted parameters given by the flooring manufacturer
• honour 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
