Kerakoll Proflow Smooth Floor Smoothing Compound

Description Kerakoll Proflow Smooth Floor Smoothing Compound is a high performance two component smoothing compound. Free flowing and rapid setting with prolonged working time. The advanced formulation allows for effortless application whilst maintaining control under the trowel. Developed to offer high flow properties, exceptional repair properties, extended working and wet edge times and a surface finish ideal for direct bonding of LVT and other resilient flooring. Kerakoll Proflow Smooth is moisture tolerant and can be used below a DPM. It is designed for self-smoothing adjustment of irregular and uneven substrates, with rapid setting and drying, compensated shrinkage. For thicknesses from 3 to 12 mm. Kerakoll Proflow Smooth can be used with the following covering materials:  LVT and design flooring, vinyl, sheet vinyl and safety flooring, mosaic tiles, textiles, rubber, PVC, linoleum, carpet and raised floors. Kerakoll Proflow Smooth can be used on the following substrates: Mineral screeds made with Kerakoll Keracem Eco as binder or pre-mixed product Cement-based screeds Calcium sulphate-based screeds Prefabricated concrete or fresh concrete castings Ceramic floors Flooring grade plywood Flooring grade asphalt/bitumen Epoxy DPM Internal floors in domestic, commercial and industrial applications Do not use in external applications, or areas that are continually submerged. 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 before installing resilient floor coverings. Kerakoll Proflow Smooth 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 such as suitable primer from the Kerakoll Primer range, diluted or neat according to the product datasheet, linked below. Mixing: Pour the pre-measured 5 l bottle of Kerakoll Proflow Smooth liquid into a clean container; then pour in a bag of Kerakoll Proflow Smooth, while shaking. Mix with a mechanical mixer until a smooth, lump free and smoothing mixture is achieved. Larger quantities of Kerakoll Proflow Smooth 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 Smooth features a high degree of self-smoothing 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 Smooth is generally applied with a flooring trowel, cam rake or pin level. The use of an aeration tool or spike roller can be used but is not required to further improve the surface finish of Kerakoll Proflow Smooth, but will work to remove entrapped air from the mixture. If an additional application of Kerakoll Proflow Smooth 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 Smooth must be primed with a neat coat of suitable primer from the Kerakoll Primer range 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.
