Application FAQs

It is not recommended to apply solvent-borne coatings when the temperature is likely to drop below 5°C during application and drying.

It is not recommended to apply water-borne coatings when the temperature is likely to drop below 8°C during application and drying.

Water-borne coatings for wood are quicker drying and have different flow/levelling characteristics to traditional alkyd based (solvent-borne) coatings. It therefore recommended to use brushes designed for the application of water-borne coatings, and not to apply in extremes of hot or cold conditions.

A water-borne coating is generally more flexible than a solvent-borne one, and the general rule if in any doubt, is “Preferably recoat water-borne with water-borne”. Provided, however, that the existing finish is sound and fully dry, there is no problem with overcoating solvent-borne with water-borne or water-borne with solvent-borne.

For a low sheen finish, three coats of Sadolin Classic would be an appropriate treatment for Western Red Cedar

Providing the surface is sound, there will be no problems in applying these woodstains. Any peeling or flaking areas must be removed, and any bare timber thoroughly sanded back to clean, bright wood. Bare areas should be patch primed with a basestain such as Sadolin Classic to even up the colour, and then one or two coats of Sadolin Extra can be applied.

On average, every litre of woodstain will give two coats, indoors and out, on two partly glazed doors or four windows.

Care should be taken to avoid spillages on to glass, cement, brickwork, carpets, clothing etc. If spilled, the solvent-borne coatings should be removed immediately while wet using white spirit. Water-borne coatings should be removed using a warm detergent solution. Once dry, the coatings will be very difficult to remove without damage to the surface.

High solids coatings differ from conventional stains on the following points: Lower emission of volatile organic compounds (VOCs); greater absorption/penetration into the timber surface, giving improved adhesion; greater flexibility to cope with timber movement; slower initial drying giving a longer open time and better flow/levelling characteristics; superior protection with the application of two coats instead of three.
