MD Building Foam Backer Rod, Gray, 1/2in x 20ft for Medium Gaps

Really happy with this foam backer rod. It arrived right on time and in perfect condition, no damage at all to the packaging. Works exactly as described and made packing large gaps before caulking so much easier. Great quality material and easy to use. Would definitely buy again for future projects.

Excellant

Though intended for sealing concrete gaps, this M-D Foam Backer Rod is an absolute game-changer for Doberman owners using DIY methods for ear posting. ​Perfect Density & Size: The 1/2 inch size and density are ideal for creating a stable, lightweight, and comfortable post core that is custom-cut to fit the ear canal perfectly. ​How to Use: The key to success is modification! It worked perfectly when wrapped in duct tape (or Zonas tape) to give it a firm, smooth exterior. This combination creates a far superior post than many specialized materials. ​Value: With 20 feet of material, this set offers incredible value, providing enough post material to last through the entire posting process for one or more puppies. ​If you are posting Doberman, Great Dane, or Boxer ears, forget the expensive custom kits—this backer rod, wrapped in tape, is the professional-level core you need. Highly, highly recommend!

There is no flexing with this product. It cannot be squeezed/pressed into a joint. Think of a pool noodle made of solid plastic.

High quality & works just as advertised. Seals like a champ. When it comes to sealing air gaps whether it be around window frames, doors, moldings, baseboards, concrete, etc. you get what you pay for. Go for the better quality. It's easy to use, cut, install, highly versatile. This is a great & trusted product.

This backer rod works well for sealing larger gaps and preparing joints before applying caulk or sealant. The foam material is flexible and easy to press into cracks, expansion joints, and uneven spaces without tearing apart during installation. It compresses nicely to create a solid base for caulking, which helps reduce wasted sealant and gives a cleaner finished result. The 1/2 inch thickness is useful for common concrete gaps and smaller repair jobs around the house or garage. The material feels lightweight but durable enough to hold its shape once installed, and the 20 foot length provides enough coverage for multiple projects. It is simple to cut to size and easy to handle even for someone without much repair experience. Considering the ease of use, effectiveness, and the amount included, it offers good value for the money for home sealing and crack filling projects.

I use this for posting ears i order 5/8 in and it looks half very flimsy and feels cheap and maybe works for uggin holes but i wouldnt buy it again
