For tank linings, brush and roller application shall be limited to pre-coating and repair areas or small repairs. The product requires heavy-duty spray equipment; the spray hose shall be as short as possible. Spray parameters are indicative and may be adjusted to site conditions. Pressure values apply to the material at 20°C. (*Consult the company representative where other application methods are required).

Depending on the end use and service area, the product may be specified at film thicknesses other than those indicated. This will alter the spreading rate, drying and curing times and recoat interval. To achieve optimum performance, avoid excessive film thickness.
In addition, curing is accompanied by shrinkage. Therefore, the actual solids content and spreading rate are lower than the above values. When estimating coverage, an actual solids content of 85% is recommended, depending on the application and curing conditions.
- Previous coat: none or in accordance with Hempel's specification. Recommended product: Hempaline Prepare 120.
- Subsequent coat: none or in accordance with Hempel's specification. Recommended product: Hempaline Defend 740.
