UNIFIX

UNIFIX is used as a thin bed adhesive for the installation of vitrified and earthenware tiles, clinker, mosaic and natural stone materials with high water absorption, which are not sensitive to discolouration or translucent. UNIFIX is suitable for an assured installation to all substrates in accordance with DIN 18157, part | e.g. concrete, aerated concrete, render, plaster, cement-based and calcium sulphate based screeds / heated screeds, masonry work, plasterboard etc. It is also suitable as an adhesive for lightweight construction boards e.g. those made with extruded polystyrene and for the installation of tiles onto mineral-based and dispersion-based SCHOMBURG bonded waterproof membranes in wet duty class AO in accordance with the ZDB data sheet “bonded waterproof membranes”.

The substrate must be dry, load-bearing, adequately flat, free from penetrating cracks and free from separating substances such as oil, paint, laitance and loose areas. It must have a largely closed surface texture with a surface condition and strength commensurate with its type. When installing tiles, the
substrate, its preparation and workmanship must conform to DIN 18157, part 1. Prime porous substrates with ASO-Unigrund. Calcium sulphate screeds must be abraded, vacuumed and as with all calcium sulphate based substrates, primed with ASO-Unigrund, diluted 1:3 with water. Heated screeds must be commissioned to recognised technical regulations prior to the installation of floor finishes. The readiness of the substrate to receive surface finishes is to be determined by moisture measurements with a carbide hygrometer (CM device).

The CM moisture content may not exceed:

• CT 2.0% for screeds on insulation or separating layers, in interior areas
• CA without underfloor heating < 0.5%
• CA with underfloor heating < 0.3%

The CM measurement is to be carried out in accordance with the FBH-AD work instruction taken from the technical information “coordination of cut out points with heated screeds”.
