If brush or roller application is used, multiple coats are required to achieve the specified dry film thickness. Never thin beyond the range permitted by local environmental regulations. For brush or roller application, a suitable thinner or brushing agent may be used as required. HEMPEL brush/roller additive 99140 may be used to improve flow and levelling. Consult Hempel for advice. Spray parameters are indicative and may be adjusted to site conditions. Pressure figures apply to material at 20 °C. (*For other application methods, consult the company representative.)

To achieve optimum performance, avoid excessive film thickness. 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.
— During and for a period after application, film formation may be adversely affected by light rain, high humidity and/or condensation: "12 h, 20 °C/68 °F".
