|Type:||Harpuis has been a well tried and tested means through the ages to keep wood really well. Our Harpuis is made, according to an old process of pure natural raw material, as it was made then in the harbours around the Zuider Zee. Harpuis does not contain any volatile components like turpentine or any other dissolvent.|
|Characteristics:||Harpuis stays fatty and plastic for a long time and is a splendid water repellent.|
|Application:||On all kinds of wood on ships, above the Plimsoll-line (waterline), against water soaking into the wood and thus against discolouring and rot. Especially the spars, the leeboards etc. are splendidly protected by Harpuis. Besides exactly in the places where cracks or wind rips have occurred in the wood or where a fitting has been fastened, screwed or nailed Harpuis gives really good sealing, because it keeps its elasticity. In this kind of difficult places, a varnish or a wood protective often gets cracks so that water soaking into the wood becomes a possibility and the wood is going to rot.|
|Processing:||Harpuis remains fatty and plastic for a long time. So preferably do not use on seats. Harpuis should be heated up somewhat before use. The easiest way is to heat the tin in a bain-marie, while stirring until well hand-hot (=about 40°C) Harpuis dries slowly, especially when the weather is cold. That is why it should be applied preferably in summer. In bright sunshine Harpuis is absorbed by the wood very well. The wood should be well dried and not preliminarily been treated by a sealing layer. If the wood should have been preliminarily treated with a wood preservative then this is not problematic. Possible layers of varnish should be taken off until the wood is reached before one is going to apply Harpuis.|
Number of layers: for a first treatment it is useful to apply two layers, especially there where the Harpuis is absorbed by the wood in great quantities. Harpuis must never be thinned, but it should be heated before use, it is well thinned and it can be absorbed very well. The second layer can only be applied when the first layer has dried well. Even when the weather is hot, there should be a period of 10 days for this.
Touching up and upkeep: Harpuis can be applied layer upon layer for many years without any chance of cracking or blistering. Too thick layers or dirty layers can be scraped away if necessary with a piece of glass or something like that. Apply a new layer afterwards.
Coverage: about 6 m5 per litre (dependable on the absorbing capacity of the wood).
