applying helmsman spar urethane to a spanish cedar door

I have an outdoor porch and shower stall that is finished in cedar. There was originally a sealer applied but after 4 years it is flaking and pealing off. I have used a marine spar varnish on my mahogany front doors and they still look great although they get very minimal direct sunlight. 【Get Price】

A spar urethane finish is applied to many different wood features interior and exterior. Sanding plays an important role in applying urethane. When you apply several coats of urethane you need to sand between each coat to help the next coat stick. You can also sand out brush strokes and bubbles. 【Get Price】

“I am using Helmsman Spar Urethane to refinish the front door of our house. It’s a one piece flat door — no recessed panels. I am applying it with a quality brush but I still get brush marks and hi-low points also tried a sponge brush with same results. I know it’s barely noticeable but I absolutely abhor brush marks. 【Get Price】

Apply a thin coat of Helmsman® Spar Urethane using a high quality natural bristle brush. On unfinished wood apply sufficient material to seal open joints edges and end-grain. Let dry at least four hours then sand entire surface lightly with very fine sandpaper (220 grit) to ensure an even finish and proper adhesion of additional coats. 【Get Price】
