Drying time<\/div>
\nDrying time is highly temperature dependant- whereby temperature refers to surface temperature during the drying process. Low temperature delays drying, and higher temperatures speed up drying. Every 10% increase in temperature will have a significant effect in drying time. The chemical curing of two-component products usually requires a minimum curing temperature of + 10 oC since the curing process will draw to a halt at lower temperatures. A second important factor in the drying process is the relative humidity. The higher the humidity, the longer the drying will take. Relative humidity above 80% is critical (surfaces can become matt, with the dew point being reached in localized points). Furthermore, air circulation and sunlight should also be taken into consideration. Since solvent vapors are heavier than air, when working in a closed room, ensure good air circulation to avoid the slow drying and mat surfaces that vapors can cause.\n<\/div><\/div><\/div><\/div>

Dew point<\/div>
Dew and frost are well known phenomena. Their formation is due to the different saturation levels of water in air at different temperatures (a cubic metre of air can hold approx 1gr of water at \u201318 oC, 5gr at 0 oC, 20gr at +23 o C and around 30gr at +30 oC). When the maximum amount of water, which can be held by the air at a given temperature is reached, the relative humidity is said to be 100%. Cooler surfaces can become covered in a dew film, which can be invisible, brought about, for example, through wind, evening cooling, tanks being filled, drying rain, or through drying paint. For this reason it is usual practice only to carry out coating work when the temperature is at least 3 oC above the dew point (or at maximum relative humidity of 80%) \n<\/div><\/div><\/div><\/div>

Intervals between Coats<\/div>
\nFor all one and two component products both a minimum and maximum interval must be closely adhered to. The interval between coats is applicable not only to re-coating of the product with itself, and also to coating with further products. An \u201cearly\u201d application of a further coat leads to solvent enclosure, resulting in deficient curing. In turn this will cause blister formation when under water loading. \u201cLate\u201d application of the following coat hinders bonding with the new coat since, in the case of two component products; the material is already totally cured. Where the maximum interval is between coats has been exceeded it is essential, also in the case of one-component products, that the surface be matt-sanded before the new coat is applied (ensuring the mechanical fixing of the newly applied coat).\nFor this reason many thin layers are recommended, rather than the fewer thicker layers. Where lacquer is applied too thickly it will not harden properly, which can lead to surface wrinkling, \u201ctears\u201d (droplets) or ridges which will have to be laboriously sanded down the years.\n<\/div><\/div><\/div><\/div>

Systematic Protection of Wood<\/div>
\nThe painting and renovation of yachts and boats of wooden construction is one of the most satisfying jobs of all, providing a real feeling of achievement. The result of a good coating is immediately visible, and the lengthy preparations are soon forgotten.\n A paint coating not only brings out the natural beauty of the wood, but also ensures the value of the vessel almost indefinitely - with minimal effort and expense. Using our coating system \u2013 specially developed for all types of wood used in boat construction \u2013 annual overhauling work is kept to a minimum. With correct application of the product, the time taken will hardly be more than that necessary for a boat constructed of fibre glass reinforced plastic.\nEven when it sometimes appears to be the case the correct use of a brush and paint is easy enough. Inexperienced painters can achieve good results in a relatively short period of time \u2013 providing the following simple, but important guidelines are followed. Even the best paint will, in the long term, not bond properly with a poorly prepared surface.\nHence the first rule:\n
