How to Cut

For the smaller thicknesses you can use a utility knife to scribe and break the shims. For the larger shims you can use razor knife, a multi-tool, jigsaw or circular saw to cut them to length. They cut like butter!

How to Attach

BIG ASS SHIMS ™ are designed to fit perfectly along the edge of Two By material. You can use a pneumatic staple gun, screws, finish or brad nailers to attach them. You can use small nails by hand or we also recommend using Instant Power Grab. Always pay attention to the length and size of your fastener so you don't penetrate electric, plumbing or hvac!

Installing Sheet Goods On Top of BIG ASS SHIMS ™

When installing drywall, plywood, osb or waterproofing on top of BIG ASS SHIMS ™ it's important to take the thickness of your shims into consideration. For example: When installing 1/2" drywall directly to a stud it's common practice to use a 1.25" drywall screw. Let's say you use a 1/4" BIG ASS SHIM ™ then you could consider us a 1.5" drywall screw to ensure you have the proper. It's important to follow the manufacturer's recommendation to ensure your sheet good has the proper mechanical bond.

Proper Use

⚠️ WARNING
Big Ass Shims™ have a compressive strength rating of 6–8 MPa. These shims are NOT designed or intended for use in load-bearing applications. Improper use may result in structural failure or personal injury.

For any project involving load-bearing weight, a licensed engineer must be consulted to perform all required weight and safety calculations. In such cases, engineered solutions such as steel shims, high-strength grout, or other products specifically designed and approved by your engineer should be used.
