Asked by Cheryl June 15, 2021
3
Answers

It would help them last longer but leaving them out in all weather they won't last a long time. The burlap will move expanding and contracting with heat and cold. The poly is ridged and will crack from the movement allowing moisture to get inside. With that the moisture has few places to escape causing rot. A better choice might be the waterproofing you use for shoes and boots. Leaving burlap out in the weather will shorten it's life as it is not made for it but the project sounds like it would look great and if you have to redo it in a few years it may be worth it. Good luck

Happy to help! While Rust-Oleum Varathane Oil-Based Spar Urethane can be used on previously painted surfaces, we do not recommend it for use on surfaces that will be exposed to foot traffic. The consistent stepping on can cause the coating to chip and peel. - Rust-Oleum Product Support 3

Turned my sons project yellow
My son was building a cornhole set and was told by homedepot employee to use this product. After applying it the paint had a strong yellow tint. After Another employee said that happens with Oil based.

Response from Rust-OleumSupportJun 15, 2021
That is not what we like to hear, Phil! Oil-based spar urethane and polyurethane does have a natural amber hue, which can cause a yellow appearance if applied over a white or light color painted surface. We recommend using a water-based clear coat, such as our Varathane Water-Based Spar Urethane for these types of applications, where a crystal clear finish is desired: https://www.homedepot.com/p/Varathane-1-qt-Clear-Satin-Water-Based-Outdoor-Spar-Urethane-2-Pack-250241H/202057149 - Rust-Oleum Product Support 2 Rustoleum

Used oil based sealer on exterior post. It looks great but did not last very long. After 1 year the coating was peeling and cracking. Looks like i will need to sand and recoat every year.

I was lookin for a good exterior sealer finish for a 'mini library' I built for a friend's neighborhood that would be exposed to the elements. The finish was applied over Douglas fir T&G siding and on the cedar shingle roofing. The product applied easily and dried evenly. Two coats gave me the look I was after, and I am confident it will stand up to the elements.

This urethane works great. Used it on a raised herb garden and it's holding up great. The wood hasn't weathered and looks as good as the day it was built. Urethane dried quickly and was easy to add multiple coats.

Not a clear finish! More yellowish-honey-color results
This product was recommended for my project. I wanted my outdoor patio furniture light and bright. I used Varathana Antique White and wanted a clear satin finish. This spar urethane turned my white furniture more to a yellowish, almond, honey whatchamacallit color! Super disappointed. Waste of money and materials as this wasnt the look i was going for. Ugh. The pic shows the difference

That is not what we like to hear! Our Varathane Oil-Based Spar Urethane has the natural amber hue typical of oil-based polyurethane and spar urethane or varnish.
