Description
Kerakoll Proflow Smooth 2 Part Self Levelling Compound 20kg is a high-performance, double-component smoothing compound for creating a flawless, flat finish ahead of LVT and other resilient floor coverings. Supplied as a two-part system (20kg powder bag + 5L liquid bottle), it flows freely, sets rapidly and gives you a prolonged working and wet edge time, so you stay in control under the trowel.
Developed for installers who need a premium surface finish for direct bonding of LVT, vinyl and other resilient flooring, Proflow Smooth is moisture tolerant and can be used below a DPM. It can be applied by hand trowel, cam rake or pin level from 3mm to 12mm, with foot traffic after approximately 90 minutes.

Prime with Kerakoll Primeplus (cement screeds, concrete and calcium sulphate screeds – diluted, with calcium sulphate screeds diluted 3:1 followed by a neat coat) or Prime+ Grip (ceramic, plywood, metal, epoxy DPM and asphalt – undiluted). Fit perimeter expansion strip around the room and honour all movement joints. For a second layer, allow approx. 3.5 hours then prime with Prime+ Grip.

Frequently Asked Questions
What depth can Proflow Smooth be applied at?
From 3mm up to 12mm. Do not use it to correct irregularities greater than 12mm.
How do I mix it?
Pour the pre-measured 5L bottle into a clean container, add the bag while shaking, then mix with a mechanical mixer until smooth and lump-free. Leave to rest for around 2 minutes and briefly mix again. Do not add extra water.
Can it be used below a DPM?
Yes – Proflow Smooth is moisture tolerant and can pre-smooth a floor at 95% RH before a surface epoxy DPM is applied.
How long before I can lay LVT or vinyl?
Approximately 3.5 hours at +23°C and 50% RH, with foot traffic possible after about 90 minutes. Allow 12 hours before resins or paint.
Do I need to prime the subfloor?
Yes. Use Kerakoll Primeplus on cement-based screeds, concrete and calcium sulphate screeds, or Prime+ Grip on non-porous and wooden substrates.
Can I use it outdoors?
No – Proflow Smooth is for internal floors only and is not suitable for areas that are continually submerged.
