I am using Unicorn Spit on a stepping stone

Seal, seal, seal! Make sure its NOT water based sealer. Unicorn Spit is water based itself, so oil based is the only finish you want.

It also will give it lots of dimension.

Hi Patandnan,

You'll need either a wax or an oil-based sealer. For outdoors, I think the sealer would last longer. Also be aware that you might need to give it several coats and possibly a refresher coat every year, depending on your climate. Wishing you the best.

Why are you not using cement paint? That is made for cement!

You have to seal unicorn spit. It is water based and will wash out with every rain or irrigation. I took a test piece that I had coated over a month ago, ran a wet rag across it and color started to migrate to the rag. Use an oil-based sealer.

Unicorn spit gets shine (light reflection) from the sealer. You get less shine from satin finish sealer than from a gloss sealer. https://amicainc.com/wp-content/uploads/2017/02/parer-type.jpg

Make sure that whatever sealer you choose exceeds ASTM D22047 slip resistance requirements, so your stepping stone doesn't become slippery. Here is a guide for choosing a concrete sealer. https://www.concretenetwork.com/products-sealer/buying-tips.html
