Self-leveling subfloor materials (SL Plasters)

Flooring material with self-leveling property. Using these products, a smooth subfloor can be constructed quickly just by smoothening it using a rake.

Features of self-leveling subfloor materials (SL Plasters)

1． High fluidity

It has high self-leveling property and ensures high fluidity with flow value of 200 ~ 250mm.

2． Quick to cure

Curing time is fast, especially in New SL, light walking is possible on the day of pouring.

3． Construction time and labor saving

Construction is easy and it cures at the prescribed time, so the construction period can be shortened. Also, in the Kanto area, it is also possible to work on a large area by using tank truck.

4． High strength

Each product has high compressive strength. SL Plaster: 20N/mm², SL Plaster SK: 35N/mm²

5． No shrinkage

No need to worry about shrinkage cracks, as excellent adhesion to the base surface can be expected from these products.

6． Adaptable to various base surface such as during repairs

By using specifically made primer, construction is also possible on the base surfaces which are usually difficult to construct as follows:

・Synthetic rubber type, vinyl acetate type, acrylic resin type adhesive (white paste) coating base
・Asphalt adhesive (black paste) coating base
・Porcelain tile	・Terrazzo	・Colored concrete
・Urethane-coated floor	・P Tile	・Plywood

Applications

・Smoothing rough surfaces (ALC, concrete, etc.), priming uneven surfaces
・Boundary floors in wooden housing complex
・Correcting uneven surface during floor repair
