Surface Preparation

Substrate should be sanded with a #120, 150 or 180 grit stearated paper and free of dust and all contaminants. This primer cannot be used on metal, old oil or cellulose lacquers.

General Information

Mix Chemlife 24 White Primer thoroughly, then catalyze and reduce material as recommended. Chemlife 24 White Primer must be well mixed while adding catalyst and reducers and must be agitated at all times to ensure product consistency. Chemlife 24 White Primer is applied in one or two coats and can be used as a primer for most wood and wood products meant for interior use. A thorough sanding using 240/320 grit stearated paper between coats is essential for adhesion. The second and subsequent coats must be applied the same day as the previous coat is sanded. Care should be taken to avoid sanding through the primer coat. With profiled edges, care must be taken with sanding of primer to avoid sanding through sharp edges. Complex profiles or profiles with sharp corners may cause difficulties in obtaining an effective primer coat of even thickness. In these cases, profile design must be discussed with your technical representative. Contact with metal surfaces should be avoided once the Chemlife 24 White Primer has been catalyzed. Recommended film build of Chemlife 24 White Primer is not to exceed 4 mils dry. Total recommended film build of Chemlife 24 White Primer and Chemlife 24 White Topcoat is not to exceed 6 mils dry.

Chemlife 24 White Primer must not be polluted with oil, varnish or the like and must not be sanded with steel wool between the coats. To obtain complete cure, the primer must be applied at a temperature above 18ºC and relative humidity below 65%. When drying, this product is not to be exposed to ammonia vapors. Finished surface must not be cleaned with ammonia containing products. This may accelerate discoloration.

---

Dry times are greatly affected by film build, porosity of substrate, air movement as well as heat and humidity. Temperatures are based on actual board temperature. This may vary depending on length of time for boards to reach these temperatures. Minimum curing temperatures of 64°F/18°C must be maintained throughout the curing cycle to achieve the film integrity as stated in product features.
