What Is the Best Treatment for Redwood? What Is the Best Treatment for Redwood?

Deck treatment is required if you want your redwood to last longer and retain its beautiful hue and finish. With proper staining and care, you can prevent your redwood from cracking and rotting, especially when exposed to water.

The ideal sealant for maximum protection of redwood deck is a semi-transparent stain. Before applying the stain, here are some tips on how to protect your deck and make it look new after years of wear and tear.

Cleaning the Deck

A cleansing solution specially made for spot-treating decks should be used. Do not dilute it and make sure to follow label instructions. A mild-washing detergent can be helpful when dealing with oily spots.

Since redwood is a resilient and durable type of wood, you can scrub the exterior surfaces with a stiff broom or hard-toothed brush. Rinse thoroughly the brushed portion before moving on to another portion of the deck. It is normal to see a small layer of redwood removed after rinsing.

Use 1 gallon of warm water in a non-metallic container mixed with 4 oz. of oxalic acid crystals for severe mildew infestations.

Proper drying after rinsing the deck is very important. It may take days before the redwood deck will completely dry.

To restore your redwood’s color, use a bristle brush to scrub the wood’s surface. You can use a solution of 1 cup trisodium phosphate and 1 cup of household bleach mixed with 1 gallon of water.

Choosing the Best Treatment

Redwood tends to crack and peel when treated with exterior finishes such as varnishes and polyurethanes. They are also difficult to apply and remove at the same time. On the other hand, oil treatments for redwood should also be avoided because of its susceptibility to mildew which contributes to wood darkening.

Semi-transparent stains are perfect for treating your redwood. These stains do not peel or flake off as compared to solid stains. You can either choose to buy a semi-transparent stain that resembles the color of your redwood or match the stain color to that of your house.

Using a vapor barrier will help you solve your redwood’s paint peeling, flaking and blistering. These barriers can be installed on the warm side of your wall to help absorb moisture.

Applying the Stain

Now that you’ve chosen the ideal stain for your redwood, you can now apply it to the wood itself. It is important to remove previous finishes first before applying the stain. Sanding is recommended in removing pigmented stain finishes. To prevent nail stains, nail heads should be set below the surface before sanding. Paint and varnish removers can also help you remove finishes before applying your new stain. Heat is usually used in paint removals.

In applying your redwood stain, you can either use a paint sprayer or a roller. A large brush can help you apply the stain to the wood’s interior surfaces and seal the wood off at the same time. Combining the use of a large brush and a roller will make the job easier and faster.
