1. Choosing a Sealer for your Redwood Deck
It is essential for one to make sure that they select a deck sealer that is specially formulated to repel water,
prevent mildew and avoid color fading. Sealants are usually either water based or oil based. Oil based sealants
do not require much looking after and less re-coating as compared to a water based finish.
Clear water repellent sealer provides basic protection, including water resistance, minimal UV protection and at
times also prevents mildew growth. Since the ultraviolet protection is minimal, the sealer allows the redwood to
change its color to a silvery gray. However, it protects the decking material from splitting, warping or cracking.
Clear water repellents require a re-coating at least once a year.
Wood toners are very much like clear water repellents, except they add in a hint of color in order to preserve
and restore the original beauty of the wood. They provide the same level of protection as clear water repellent
but are likely to last longer.
Clear wood preservatives provide a high level of UV protection and therefore prevent the redwood from aging
and graying and are often used to restore the natural color of redwood and can last for as long as two years.
Semitransparent sealers are subtle and display the lumber’s grain and texture. These sealers comprise of a
pigment that protects the wood from sunlight more than any other sealant. Oil based semitransparent sealants
offer the highest protection, better color preservation and longer lifespan.
When choosing a sealer, it is essential to bear in mind that the finished color varies depending on the wood
itself. If one intends to apply a new sealer over an old one, they must pick a color that is close to or darker than
the original color. It is always advisable to experiment with a sealer by using it on an inconspicuous area before
using it on the redwood to make sure one gets the shade or tone they’re looking for. Redwood contains certain
pigments that bleed to the surface, therefore one must use a darker stain color which makes the bleeding
invisible.
