SCHÖNOX® KH FIX Ready Mixed, Solvent‑Free Acrylic Primer, 1.3 Gallon Kit

This ready-to-use, solvent-free acrylic primer is especially suitable for use on calcium-sulfate-based substrates (gypsum) as well as to bind residual dust and improve adhesion prior to installing luxury vinyl tiles (LVT) on suitable substrates using the SCHÖNOX ROLL AND GO™ adhesive.

SCHÖNOX KH FIX offers high coverage rates and short waiting times. This rapid-drying primer is ideal for use on both interior and exterior floors and walls. It is also suitable for use on floor heating systems.

This solvent-free primer is fast film building and low odor. It is rated EMICODE® EC 1^PLUS for very low emissions.

SCHÖNOX KH FIX is suitable on:

• Gypsum based substrates
• Concrete, cement based substrates
• Old water-resistant adhesive residues
• Particle board, OSB board, wood
• Gypsum board (walls)
• SCHÖNOX self-leveling compounds, preferably SCHÖNOX AP, or smooth porous concrete prior to installing LVT using the SCHÖNOX ROLL AND GO™ adhesive following the referring product data sheet

*All values are approximate at 65°F floor temperature, are subject to local climatic fluctuations and vary according to the absorbency of the substrate and to the applicator device. Lower temperatures will lengthen the working and curing time, higher temperatures may shorten it significantly. Do not install underlayment or topping before the substrate has dried thoroughly.
