Waterproofing Ideas for a Bat

Most store-bought baseball bats are coated with a water-resistant finish. But waterproofing protection is compromised as bats age and wear out, and it's absent altogether on raw wooden bats. To avoid rot and rust when you leave or use a bat in the rain, you can add a fresh water-resistant finish to your favorite wooden or aluminum bat.

  1. Pine Tar

    • Among the oldest water-resistant agents in baseball is pine tar. This substance has its roots in the ancient world, where it was used to waterproof wood and ropes. Ballplayers use pine tar to repel moisture and improve their grip on bats. But pine tar is sticky, messy, and can be damaging to other equipment like balls and gloves. Applying it beyond the handle area is also frequently prohibited by league rules. When it comes to waterproofing an entire bat, consider other options.

    Linseed Oil

    • Linseed oil is an effective waterproofing agent. Make sure your wooden bat is sanded smooth, and then leave the knob of the handle dipped in linseed oil overnight. The oil will be soaked up along the entire bat, adding to its strength. Then coat the bat in linseed oil using a brush. For best results, repeat the sanding and coating process, and boil and cool the linseed oil before use.

    Silicone Sealant

    • For aluminum bats, you'll need to take a different approach. Although most new metal bats are coated with a sealant, a bat that has taken some use and abuse may require a new coat. Silicone sealant can be used for waterproofing. An aluminum bat usually has a rubber handle, which you should cover with tape before applying sealant. Then simply brush on the waterproof silicone. Allow the bat to air dry.

    Other Methods

    • Another method of wooden bat waterproofing is using a coat of a beeswax-based solution. Wax repels water, although it may need to be applied more frequently or on top of a primary finish. Bats are also finished and waterproofed with various types of polymer-based lacquers. With commercial lacquers, look for nontoxic products and work in well-ventilated areas.
