Do You Need Two Coats of Semi-transparent Stain?  5/5 (2)

Do you need two coats of semi-transparent deck stain?

Whether or not you need two coats of semi-transparent stain depends on several factors. Different brands of semi-transparent deck stain have different application instructions. Apply a second coat when the deck stain instructions indicate you should do so. Some decks need two coats depending on the color, type, age, and condition of the wood, what type of stain was previously used, and proper maintenance. Most semi-transparent penetrating deck stains do not need a second coat on well maintained and prepared decks. New decks typically only accept one coat of deck stain as it is harder for the semi-transparent stain to penetrate into newer wood.

After one coat of Flood water based sealer on stripped and sanded 10 years old treated boards rain water does not bead T all do I need a second coat?

11 months ago

Two years ago I sanded off the Cabot solid stain the previous homeowners used to make the deck look nice in order to sell the house. It started peeling up in long strips 6 months later in the Spring. I cleaned, brightened, and laid down two coats of Butternut Defy Semi-transparent Stain.

Now it is looking kind of worn in certain areas with areas on and around knots looking bad. I want to throw down a maintenance coat to bring back the new look and beef up the water repelling/uv defense. It’s an old deck (my guess is around 30 years old) but has had what appears to be a handful of deck boards replaced in the last 5 years.

I purchased the Defy deck cleaner and I plan to spray it on tomorrow, scrub and wash it off and give it 48 hours to dry before applying the stain Thursday morning.

How many coats of stain do I need to lay down? Any advice would be appreciated.
