7 Best Finish for Cedar Siding 2021 [Reviews & Guide]

Cedar is a wonderful material for construction. It can endure a long period without staining or sealing it, but it will ultimately show indications of wear. Protecting and revitalizing your cedar buildings and furniture with a high-quality stain might be a smart decision for the best lifetime, whether it’s a new project or an older surface that could use a refresh.

When it comes to cedar used outdoors for decks, fences, siding, and furniture, choosing the right finish is crucial. These finishes are exterior-grade, contain sealants, and protect the wood from moisture, UV rays, and fungi-caused degradation.  It works just as well as a blanket chest or closet lining outside in the elements.

However, with so many options available, determining which finish is ideal for wood may seem impossible. This article explains the distinctions between different products and important factors to consider while shopping.

1. Ready Seal Pail Natural Cedar Exterior Stain and Sealer for Wood

Ready Seal Pail Natural Cedar Exterior Stain and Sealer for WoodReady Seal Wood Stain is a high-quality outdoor wood stain and sealer for professionals. We can recommend this to be used on decks, fences, arbors, gazebos, wood siding, roofs, and log homes, among other external wood surfaces. It drips and runs freely, resulting in a consistent finish. 

A particular blend of paraffin oil, resins, trans-oxide colors, and algaecides make up the composition. It is one of the products of this category that can give you the best clear finish for cedar siding.

The cedar deck we examined looked far better after we applied the Natural Cedar paint. Having said that, the color did fade after a few days as the paraffin oils penetrate further into the wood grain. We also need to inform you that at the 2 year mark, there was around 50% color retention.

The coverage rate of Ready Seal Wood and Deck Stain was exceedingly low. We had to apply two coats and only got around 8 square feet per gallon of paint. The cost of Ready Seal is lower than typical, but much more stain is required. Our 600 square foot deck required 7-8 gallons of Ready Seal Deck Stain to be 2-coated.

In conclusion, Ready Seal Wood and Deck Stain is a wonderful choice for a smooth, easy-to-apply finish. But keep in mind that due to color loss, it may be essential to reapply every 12-18 months.
