Directions for Use
Surface Preparation & Substrate Condition
- The steel surface should be roughened and cleaned by blast-cleaned to Swedish specification Sa 2½ grade minimum for optimum adhesion. Alternatively, the surface could be prepared to Swedish specification St 2 or St 3 grade by using power tools along with manual wire brushing to thoroughly remove loose rust/scales. Remove grease, oil and dirt. A rough, clean, dry and contamination-free surface is essential for optimum adhesion. Suitability of a primer use should also be determined for a particular surface and type of application before use.
- Also any previous paint, dirt and surface contaminations should be removed by scrubbing or using high-pressure water jets.
- The substrate temperature should be between 10°C and 50°C, and also the relative humidity should not be in excess of 90%.
