Guidance for specification option:

Once the basecoat has dried in good conditions the basecoat remains ideal to overcoat for a further four days. Thereafter, the basecoat becomes gradually harder, until it reaches a point where the overcoat may not obtain a good bond. Thermoguard therefore recommend overcoating when basecoat is dry, within the following four days in good conditions.
