Wood Types

Spruce

New spruce lumber usually has a high moisture content. Be sure to let the lumber dry. Check for moisture. Mill glaze removal should be done by using Wood Shield Wood Restorer or sanding. Spruce should be stained or the wood will deteriorate prematurely.

Pressure Treated Wood

Pressure treated wood can be stained. The actual process of treating the wood involves liquid preservatives being soaked and drawn into the wood which saturates it even further. It may take a period of time before pressure treated wood has time to dry out.

Redwood and Cedar

Redwood and cedar are premium natural decking materials. The natural process for weathering gives these woods a greyed exterior. Once this occurs it acts much like a barrier and protects from further deterioration. The strong tannins in these woods are natural preservatives. If you desire another colour than grey weathered wood you must remove these dead wood fibres and ensure wood is dry before staining.

Rough Sawn Lumber

This lumber has an attractive rustic finish. It is commonly used on siding and fences. When staining this type of lumber remember that it is porous and has an uneven surface. If you choose a semi-transparent finish, keep in mind the uneven cut may also show an uneven colour. This will be most noticeable in the darker semi-transparent stain colours. The key to this surface is to clean with a wire brush and pressure washing to dislodge dirt and wood fibres. Rinse well and allow to dry thoroughly. Check dryness using a moisture meter.
