Video Guide from GE
When dealing with sealants and caulks, we suggest that you consider the reason and applications that you are using the product for before you buy. Some sealers contain latex that can harm someone with a major allergy. Other sealers are not clear when dry, so if you need an invisible fix, you should choose one that dries clearly. We chose a variety of products that are versatile, durable, and fit for numerous jobs. We hope that you end up liking these sealers as much as we do. Products used in food preparation areas are chosen for the safety of you and your family or guests. We pride ourselves on offering as much information as we can about products you use all the time.
When using a waterproof sealant, be sure to check the curing time. You may need to let the adhesive set for 24-hours or more to dry fully. Some applications are not useful in wet areas; we suggest only using those products for wood, vinyl, plastic, metal, and glass applications away from heavy moisture. Be sure to clean the area you are going to seal before applying sealants.
If you have any rust, then you may want to send (or use rust converter) it away before applying caulk. A clean, dry surface will work the best for long-term adhesion. For more information, you can look for our list of products on Amazon. You can find in-depth reviews that talk about specific applications and results to give you a better idea of product use.
