CONSIDERATIONS
Some woodstains are waterproof - but they can also prevent natural moisture passing through the wood. This can make wood swell, breaking the bond between the coating and the wood. Sadolin exterior products are designed to form a microporous ‘jacket,’ which is both waterproof and allows the wood to breathe naturally. The benefit is greater, longer lasting protection for your wood.
CONSIDERING COLOURATION Translucent woodstains will vary in appearance depending on the natural colour of the timber surface to which they are applied. For this reason, we recommend trial applications to ensure the acceptability of the final shade. The samples below represent the colour difference shown on softwoods and hardwoods when Antique Pine shade is applied.

Exposure to sunlight and the weather causes conventional woodstains to fade over time.
CONSIDERING TIMBER CONDITION The condition of the timber may also influence your choice of coating. If the timber is unsightly, a translucent coating will not hide this, so an opaque finish would be preferable. If the timber is in good condition you may choose to highlight its natural beauty by applying a translucent coating. CONSIDERING PRODUCT There are both strengths and limitations when considering your choice between water or solvent based products. However, in order to avoid any potential problems we recommend that you are consistent through the whole system of application. CONSIDERING APPLICATION TOOLS Quality natural bristle brushes are best for solvent based systems, whereas we recommend synthetic brushes for water based.
Sadolin products use specially selected light-filtering pigments to promote longer-lasting colours.
The longer wood is exposed to the elements, the greater the risk of conventional woodstains blistering and peeling. Applying a new coat will require extensive sanding and preparation if wood is weathered. Because Sadolin products are specially developed to weather naturally, applying a fresh coat requires only minimal preparation, reducing time, expense and labour.
