Calcium Sulphate Based Self-levelling Floor Screed (10-60 mm) - SELFING 725

Description

SELFINF 725 is a calcium sulphate based, self levelling flooring compound to create even and homogenous floors that can be applied indoor application with 10-60 mm thickness.

Fields of Application

• It is used in indoor floors that required minimum thickness.
• It can be used on floors with underfloor heating and on thermal insulation materials.
• Suitable used in normal humidity level indoor kitchen and bathroom. Waterproofing is required on directly contact water wet floor areas.

Features and Benefits

• Self-levelling.
• Has high thermal conductivity.
• Has high strength.
• Provides smooth surface.
• Applicable 10-60 mm thickness.
• Does not require additional processing on coating materials such as tiles, carpet, laminate, wood, parquet and PVC.

Application Procedure

Preparation of Substrate

The application surface must be free of materials such as molding oils, dust, paints, dirt, detergents that prevent bonding. Application surface moisture rate shall not exceed 4% and the floor

shall have compressive strength of minimum 15 MPa. Proper primers should be used before the application. It is recommended to use edge strips in screed applications to prevent the mortar from leaking out and to absorb the expansion in the floor.

Application Method

20 kg SELFING 725 is slowly poured into the 4,4 liters water under low speed mixture for 3-5 minutes until homogenous mixture is obtained. The mixture is allowed to rest 3 minutes and then after mixing for 1 minute the product is ready to use. Spread it uniformly as intended thickness. Application have to be done within 60 minutes. Do not add water during the setting time. Application and surface temperature must be between +5°C to +35°C.

Application thickness according to surface types:

• As self levelling bonded screed with 10-60 mm thickness
• As self levelling floating floor screed on a separating layer with 30-60 mm thickness
• As self levelling floating floor screed on an insulating layer with 35-60 mm thickness
• As self levelling floating floor screed above heating floor systems 35-60 mm thickness

Consumption

1,7 kg/m²/mm. Recommended coating thickness is 10-60 mm.
