Applying Stains and Clear Timber Finishes
What is the difference between timber oil, stain, varnish and lacquer? This lesson explains when and why each product should be used.
Determination of bare timber surface to be stained is dependent on whether the timber is going to be interior or exterior. Read the manufacturer’s recommendations which will be found on the back of the can or on a Technical Data Sheet to ensure the choice of stain suits the environment chosen. which may be sourced from paint suppliers that carry these products.
The manufacturer of exterior stains have taken into consideration the climatic conditions whereby durability of the colour remains long term.
Upon opening the can of stain, slowly stir mixture due to pigment that may have settled on the bottom of the can. Do not shake it vigorously, as bubbles will occur, and in this condition if applied to the surface the bubbles will appear, so do not do it, remember, stir slowly.
Any repairs necessary with timber will require wood fillers or putty. These fillers may not be exactly the same colour as the surface timber, therefore it may be necessary to mix a stain or a solid colour stain applied over the putty repair, thus colour matching to the surface. Always test any colour matching on a sample board first.
