Should I treat my woodwork with a wood preservative before applying wood stain or paint?

Wood is a strong, valuable material that is alive and that reacts interactively with its environment. It is susceptible to sunlight, moisture and mould and, in addition, can be attacked by wood-boring insects or fungi. Which is why wood needs to be treated with the necessary care and in the correct way, so that any deterioration can be avoided.
 
Some types of hardwood are naturally durable, in which case it is sufficient to apply a surface treatment. Softwood and other hardwood and wood from a lower durability class are less resistant to insects, moulds and fungi, the effects of the climate and mechanical action (abrasive effect of sand and dust, scratching...) so that appropriate preventive deep treatment using wood preservatives is necessary.
 
Treatment by means of injection, as applied by DE BACKER House Construction, is the best way to protect newly sawn wood. The preservative penetrates very deep into the wood and is therefore more effective. Impregnation ensures that the life of the wood is extended and stops the natural process of decomposition and decay.

Which factors affect the final colour of my finished wood?
 
The following factors combined affect the final result:
- the natural colour of the wood and any coats already applied
- the wood's grain and the suction force at the surface
- the method of application (brush, roller, spraying)
- the amount of pigment in the finishing product and the number of coats applied

My woodwork outside was sanded and dry, ready to be coated with wood stain. It suddenly started raining hard and it rained all day. Can I treat the woodwork immediately after it stops raining or do I have to wait?
 
Although wood is porous and has an absorbent surface, it will not absorb rainwater like a sponge. The wood is wet on the outside but two days are probably sufficient for it to dry out. If it has rained for a longer period of time it will take at least a week for the wood to dry out, depending on the ambient temperature and relative humidity. Before the wood is treated the moisture content must be down to an acceptable level.
