Description
Kerakoll Proflow Trade Floor Smoothing Compound is a fast setting, two component smoothing compound. Designed for free flowing substrate preparation before laying resilient flooring. Kerakoll Proflow Trade has been formulated in order to guarantee maximum compatibility and adhesion with all kinds of organic adhesives for resilient floor coverings.
Kerakoll Proflow Trade is designed for self-smoothing adjustment of irregular and uneven substrates, with fast setting and drying, compensated shrinkage. For thicknesses from 3 to 8 mm. It 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 Trade 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 applying Kerakoll Proflow Trade. In particular, substrates must be treated with a suitable primer such as Kerakoll Active Prime Fix, diluted or neat according to the product datasheet, linked below.
Mixing:
Pour the pre-measured 5.0 l bottle of Kerakoll Proflow Trade liquid into a clean container; then pour in a bag of Kerakoll Proflow Trade, while shaking. Mix with a mechanical mixer until a smooth, lump free and smoothing mixture is achieved. Larger quantities of Kerakoll Proflow Trade 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 Trade 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 Trade 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, but will work to remove entrapped air from the mixture. If an additional application of Kerakoll Proflow Trade 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 12 hours. The initial layer of Kerakoll Proflow Trade 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.
