Buying Guide
- Application type: Determine whether you need a one-part sealant for quick jobs or a two-part system for higher durability and better UV resistance.
- Wear layer compatibility: Match the sealer to your vinyl or PVC wear layers to ensure proper bonding and seal longevity.
- Substrate compatibility: Consider whether the product is designed for vinyl flooring, linoleum, or automotive surfaces, depending on your project.
- VOC and safety: Look for low-VOC, solvent-free formulations if indoor air quality is a priority or LEED compliance is desired.
- Drying and cure times: Factor cure times into project scheduling; some sealers cure quickly, others require more time to achieve full strength.
- Kit contents: Check whether the kit includes application tips, gloves, or extra accessories, which can add value and ease of use.
- Flexibility and longevity: Consider formulations that resist shrinking or cracking and remain flexible under movement or temperature changes.
- Color options: Depending on visibility, white or black sealers may blend more effectively with the surface; some products offer clear options for near-invisible sealing.
