My son is a master of disaster when it comes to food spills, stains, and general oopsies. Truthfully, he spills something nearly every single day. In fact, our old bar stools were pretty embarrassing between rug doctor cleanings. So, when I was choosing our replacement bar stools for our breakfast bar, where we eat almost every meal, I was sweating bullets. I am not sure if it is actually possible, but I seriously considered covering them in uncomfortable hard plastic. How awkward would that be?!

Rather than limiting our dinners to uncomfortable wooden chairs, I found a trick for making fabric waterproof and thus spill-proof. And, of course, I thought I’d share!

The whole process for our bar stools took about 10 minutes, plus drying time, but I am very impressed with the results. If there is a spill, it just beads up on the fabric and I can gently dab it away with a damp sponge. Even ketchup or spills that weren’t noticed at first have been a breeze to clean.

Waterproofing Fabric Supplies

The item you want to waterproof (this can be a outdoor pillow, cushion, bar stools, chairs, or just about anything)
I use this commercial grade fabric spray for waterproofing.
A tarp or some cardboard to protect the surroundings

For 3 bar stools, I used the 16 oz bottle. Because we are using the spray on cushioned, upholstered fabric, it takes more than a thinner tightly woven fabric like a tarp or tent. The smaller bottle would cover about a medium ottoman size and several pillows. The instructions say about 40 sq feet for heavy fabrics.

How To Waterproof Fabric

You will need to use this waterproof spray for fabric outdoors because there are fumes. Full sun is also best for quicker drying and curing.

Then lightly spray the entire surface of the pillow with the waterproof spray, holding the can 6″ to 8″ away from your fabric as you spray. Make sure to slightly overlap each pass to make sure the entire surface is covered. The surface should be evenly damp, but no need to over saturate. Even though I did not experience any color change, I would recommend testing an inconspicuous area first.

The directions recommend that you do this in , so after you do all sides, let your project dry for about six- eight hours and test by pouring water on fabric. If needed, reapply to any spots that don’t fully bead, after it’s dry. When all fumes have dissipated, feel free to bring it back in the house. I let my bar stools sit out most of the day in full sun and it was great.

It has been a few months since I did this project (I keep showing the beading to all of my friends when they visit!) and they are holding up well. I do however expect they will need redone at some point, but so far so good. I will definitely be using this on our outdoor cushions as well to keep them dry and clean.

Hope this quick tip helps if you have messy eaters like I do!
