- Product Applications
- MASTERFIX 820 is recommended for bonding parquet, multi-ply and pre-finished wooden flooring, wood-plank flooring, laminate flooring, rubber tiles, carpets, ceramic, quarry tiles, chipboard, plywood, hardboard, PVC sheets, PVC tiles and fiber/cement sheets.
- MASTERFIX 820 is also recommended for bonding various insulation boards such as EPS (expanded polystyrene), XPS (extruded polystyrene), PIR (polyisocyanurate).
- Application Procedure
The surface must be dry, structurally sound and free from loose particles, grease, dirt, dust, paint, wax, etc.
The two components which make up MASTERFIX 820 are contained in pre-dosed containers. The mixing ratio is already established (resin to hardener = 7:1). Mix the two components for a minimum of two minutes using a low speed mechanical mixer, until a smooth paste with a uniform cream color is obtained.
The final chemical setting and optimum bond strength is achieved after 7 days. Pot and setting times vary depending on temperature and relative humidity.
Pour the MASTERFIX 820 adhesive out of the container but do not scrape out remnants as they may not be totally mixed and may not cure. Use the MASTERFIX 820 adhesive immediately. Apply the MASTERFIX 820 adhesive with a suitable notched trowel at 0.25 to 0.4 kg/m2 per layer, depending on the porosity of the substrate. Curing time is dependent on atmospheric conditions and temperature. Curing will be considerably retarded at temperatures below 10°C. Bulk product in the bucket will cure faster than the film spread on the substrate, due to chemically induced heat build-up during the curing process. This temperature increase is negated once adhesive is spread. Higher temperatures will generally increase curing speed and reduce open time.
