Hold-Down Bolts Prepped Right
Epoxy connections require clean attachments; here's how to ensure every hole is perfectly prepped.
I recently added earthquake tie-downs in an occupied basement. For the epoxy connections to work, every hole must be perfectly clean. Blowing the dust from the holes is a messy process, so I made a dust-capture device.
I took a 2-in. PVC tee and added a ¾-in. reducer bushing on one end. The tee attaches to my shop-vac hose and is placed over the hole. Into the ¾-in. fitting I inserted a ½-in.-dia. piece of PEX tubing attached to my cordless Makita blower. I used a handheld blower instead of a compressor so there would be no chance of oil being forced into the hole. With the shop-vac running, I blew the hole out and captured the dust with the shop-vac.
I did the same with the scrubber, alternating between scrubbing and blowing until the hole was squeaky clean. For about $3, this system works great.
