Materials

Product Information
Application

Dust reduced, light levelling screed with cement and EPS-granulates for casting subfloors. Suitable for filling spaces between wooden trusses, other filling purposes as well as for raising floor structures. To ensure the required strength, cast screed layer is smoothed with appropriate Kiilto Oy's fibre-reinforced smoothing compound (15 mm smoothing compound layer at the minimum). Suitable for both dry and wet interior areas. Thermal conductivity approx. 0.13 W/mK

1. Bonded floor / firm concrete subfloor or construction board: The substrate must be clean, solid and firm. Remove cement laitance, paint splashes, adhesive residue and other impurities and brush or vacuum the floor thoroughly.
Concrete subfloors are pre-treated with diluted Kiilto Start Primer (10–20% primer/80–90% water) prior to application of the floor screed. With building board subfloors, use Kiilto Start Primer undiluted. Cast screed layer must be at least 15 mm.

2. Floating screed: The cast is separated from the subfloor, for example, with Kiilto Valusuojakangas separation fabric or construction paper. The cast is detached from walls and inlets with separating boards/elastic sealant. Cast screed layer must be at least 30 mm. The screed is always reinforced with steel or glass fibre mesh (see separate structural pictures).
Underfloor heating cables/pipes are always fixed in the steel mesh.

Instructions and Safety
Instructions for use

Strew EPS Light DF in cool (+10–20 °C), clean water. The amount of water depends on the application method (manual/pump) used.
To ensure a uniform mix, always use entire bags.

Apply evenly by using a darby float and/or a wide steel trowel. The screed is then floated to make the surface dense and smooth. Protect the fresh screed surface from drying too quickly. If the surface can't be smoothed within 5 days of casting, cover it with a plastic film.
