How to Clean and Seal Cypress Wood

Cypress contains cypressene oil, a natural preservative that gives cypress wood resistance to corrosion. Cypress easily accepts stains and paints, but you can leave it natural. While some people find naturally aged cypress to be the most attractive, others argue that regular cleaning and sealing is the best option.

Interior and Exterior

Cypress can be used wherever other types of wood are used. Interior trim is an example. However, due to good weather, the majority of cypress is used for structural members such as exterior decking, siding, fencing, and beams.

Cyprus Interior Cleaning

Indoor cypress is usually finished with lacquer or varnish. Clean it with a mild soap and water solution as you would any other finished wood. Follow up by buffing it with furniture polish.

Cypress Exterior Cleaning

Appearance Cypress presents discoloration, mildew, and stains, and is typically not associated with indoor applications.

Black Stripes

The discoloration is common around fasteners used on exterior cypress. Also known as scavenging, it is more common on vertical surfaces when water washes the black streaks off screws or nails. Use a natural bristle brush to scrub the black marks with soap and water.

Blue Stain

Cyprus’ natural mineral stains are often bluish-blue, usually due to iron in the wood. Dissolve 1 to 4 ounces of oxalic acid in 1 quart of hot water to remove mineral stains. Wipe the stained area with a soft bristle brush. After scrubbing, rinse thoroughly with water.

Mold and Mold

Mold and mold are basically the same things that create black dots, specks, or streaks. Or it may come in a grayish tint. Clean with a natural toothbrush using a solution of household bleach and water.

Tamer Alternatives For Cleaning

Oxygen Bleach

If you are hesitant to use a powerful vacuum cleaner, here are a few alternatives. Oxygen bleach is a powder. Mix it with the recommended amount of water, place it on the tree with a soft brush and rinse it with a garden hose.

Vinegar and Soda

The simplest product for cleaning cypress can contain equal parts of white vinegar, warm water, and baking soda. Thoroughly clean the cypress with a cypress brush and rinse with a hose.

Sealing Cyprus

Water-repellent preservatives that contain mold and moisture inhibitors can extend the life of cypress. Please refer to and follow label instructions as products differ in application and formula. Preservatives work best when the outside temperature is above 50 degrees and should not be applied if rain is expected within 24 hours.

Advantages of Water Repellent Preservatives

  • Prevents extraction bleed.
  • Grain increases.
  • Slows down staining.
  • Improved paint adhesion
  • decay delay
  • Inhibition of mold growth
  • It can be used alone or as a pre-treatment for topcoats.

Stain Preparation

If the deck is stained, coat all surfaces, including cuts and ends, with an alkyd oil-based sealer. Oily products delay discoloration and mold stains that eating organic, natural oils.

Paint Ready

To use paint, coat all surfaces with an alkyd oil-based primer. Light-colored paint reflects heat more than dark colors, reducing the chance of shrinkage and warping.

Standalone

If you plan to use a clear sealer as a standalone preservative, you should apply it annually or at least two years apart.

Apply It

After washing, let the cypress dry for at least 24 hours. Applying a sealer is similar to painting. Brushing provides more depth, but the spray goes more thoroughly into cracks and cracks.

Brush on It

Wrap the perimeter, bottom, and ends of the board with a brush sealer. The brush is best on a spindle, railing, or even where a delicate touch is required. For efficiency, follow the rollers on a wide, flat surface.

Turn on The Spray

Sprinkle everything freely. Hold the sprayer 8-12 inches from the surface. Overlap each previous pass about 1 inch until the cypress is coated with a sealer. Direct the spray to cracks, seams, undersides, and down on the ends and edges of the board.
