How to Seal Terra Cotta Pots, birdhouses, mailboxes, pallet signs, plant markers and other “outdoor decor” I especially like Thompson’s Clear Waterproofer to seal terra cotta pots from water damage. You can find is at Lowes and it runs around $4 a can. All you need to do is take a thoroughly cleaned and dry terra cotta pot and spray the interior with Thompson’s Multi-Surface Waterproofer.
I had no idea you could buy this to protect outdoor fabrics! I also can't believe she bought this fabric in 2012 at a Joann's, I bought pillows from Costco in this pattern and recently found two chair cushions. Love it! #outdoor #furniture
