Nothing ruins a fresh floor faster than water seeping into the gaps and causing the planks to swell. I have spent significant time comparing the common sealers available to help you keep your floors pristine. While these products serve a purpose, I find that many owners get caught up in brand marketing. Here is the honest ranking of how these three choices compare for your home.

Choosing Between Them
I believe that Mannington MCS 42 is the superior choice for most homeowners because it offers a true chemical bond for plank edges. If you are working with large rooms and just need a finish, the Zep Floor Sealer is the logical choice, while the Roberts 7500 remains the expert pick specifically for sheet vinyl.
I recommend that you check your manufacturer guidelines first, as many modern click-lock floors do not actually require any sealant at all. For those that do, applying a quality product like the Mannington sealer provides the best protection against moisture damage.
