Deck Stain Pricing

Each type of stain offers different protection and aesthetic appeal for exterior wood surfaces.

• Clear and transparent stains. These sealants allow the natural wood grain to shine through while providing basic weather protection. They typically cost $20 to $60 per gallon (CAD 27 to CAD 83) and last 1 to 2 years. A clear finish is often the best deck stain for new lumber or premium woods like cedar and redwood.

• Semi-transparent stains. Offering a balance between protection and appearance, these stains add subtle color while showing wood texture. Expect to pay $20 to $50 per gallon (CAD 27 to CAD 69) for quality semi-transparent options that last 2 to 4 years.

• Semi-solid stains. These provide more coverage and color while still revealing some wood grain. Prices range from $45 to $80 per gallon (CAD 62 to CAD 111), with durability of 3 to 5 years.

• Solid stains. Acting like thin paint, solid stains completely hide wood grain but offer maximum protection. The longest-lasting deck stain options often fall into this category, costing $10 to $60 per gallon (CAD 13 to CAD 83) and lasting 5 to 7 years on horizontal surfaces.

• Oil-based vs. water-based. Oil-based stains penetrate deeper into wood fibers and cost $20 to $50 (CAD 27 to CAD 69), while water-based formulas dry faster, emit fewer fumes and cost $20 to $45 (CAD 27 to CAD 62).

What Is the Best Deck Stain for Old Wood?

The best deck stain for old wood should penetrate deeply and provide maximum protection. Oil-based semi-transparent or semi-solid stains work exceptionally well on aged surfaces because they soak into the wood fibers rather than sitting on top. For severely weathered decks, consider using a wood restorer or brightener before applying stain. These products help remove gray fibers and open wood pores for better stain absorption.

How Do You Prepare a Deck for Staining?

Proper preparation can determine whether your deck finish lasts 2 years or 7. Start by clearing the entire deck surface and taking care of basic seasonal maintenance.

• Clean thoroughly. Apply deck cleaner with a pump sprayer and scrub with a stiff brush. For tough spots, spray with a pressure washer set on low, but be careful not to damage the wood.

• Make repairs. Replace any rotted boards, hammer in popped nails and tighten loose screws. Fill small cracks with exterior wood filler.

• Sand if necessary. For previously stained decks or rough surfaces, light sanding with 80-grit sandpaper helps the new coating adhere better.

• Clean again. Remove all dust and debris from sanding. Let the deck dry completely — typically 24 to 48 hours depending on weather conditions.

• Check moisture content. Wood should have less than 15% moisture content before staining. Use a moisture meter or perform the water drop test: If water beads up, wait longer; if it soaks in, you're ready to stain.
