Bostik Screedmaster SL C910 Speed 30 is a rapid-setting, two-part smoothing compound for projects where time is tight. Supplied as a 20kg powder bag with a 4L polymer liquid bottle, it is designed to level uneven internal floors quickly before the installation of carpet, vinyl, LVT, tiles and other decorative floor coverings.
Using Bostik Turbodry technology, it can take light foot traffic in around 30 minutes and accept loose-lay floor coverings from approximately 45 minutes in suitable conditions. This makes it particularly useful for fast-track refurbishments, retail work, repairs and new-build projects where downtime needs to be kept to a minimum.
Prepare the subfloor carefully. It must be sound, dry, clean and free from loose material, grease, dust, old adhesive residues and other contaminants. Prime the substrate using the appropriate Bostik primer in line with the latest technical guidance; priming helps control absorption and supports a smooth finish.
Shake the 4L polymer liquid thoroughly and pour the complete bottle into a clean mixing vessel. Gradually add the 20kg bag of powder while mixing with a slow-speed drill and paddle until a smooth, lump-free mix is achieved. Do not add water or adjust the supplied mix ratio.
Apply immediately after mixing, as the working time is limited. Spread the compound with suitable smoothing tools between 3mm and 20mm, maintaining a wet edge wherever possible. Under normal conditions, light foot traffic is possible after approximately 30 minutes; loose-laid floor coverings may be installed from around 45 minutes, while bonded coverings typically require longer.
SL C910 Speed 30 is for interior installations and must be covered with a compatible floor finish. It is suitable for compatible warm-water underfloor-heating systems where the surface temperature does not exceed 27°C. It must not be used before applying a surface damp-proof membrane.

SL C910 Speed 30 is a rapid floor-preparation compound and must be protected with a suitable floor covering; it is not intended to remain exposed as a finished surface. Once cured, keep the area clean, dry and free from unnecessary traffic until the flooring installation is complete.
Clean all tools, mixing equipment and splashes immediately after use, before the compound hardens. Remove hardened material mechanically if necessary.
Because this is a fast-setting product, plan the work area, mixing equipment and application sequence in advance. Do not disturb the surface while it is curing, and confirm it is ready for the intended adhesive or floor covering before proceeding.
