Questions & Answers

Can this flooring be installed over a sound sheet vinyl floor?

1 Answer | 
Answer This Question

Good Afternoon Darren, Thank you for reaching out! We do not suggest adding a sound sheet underneath our gluedown flooring. The flooring itself has a Traveling Sound Absorption 71Db I hope this helped. If you need further assistance, please reach out to CS@lucidasurfaces.com

    Are there arrows on the back to match the pattern?

    Answer This Question

    Good Morning Debbie, The arrow in the back of the plank shows the pattern direction. We always advise to lay down the planks before installing to get a look as to who the pattern will look on the floor! -Dina

      Good Morning Jerry, Thank you for reaching out. Glue can be taken off by damping a microfiber towel and using white vinegar. Additionally, we do recommend using Bona cleaning products that can help!

        Can this be installed over sound click lock vinyl plank flooring with a foam backing on it with proper prep?
        ByJun 6, 2025
        1 Answer | 
        Answer This Question

        No, we do not recommend installing a glue down vinyl floor over an existing click lock vinyl flooring as the product will have too much bounce and not be properly secured. You would need to remove the existing click lock flooring and install a 1/4" inch of interior grade plywood to the subfloor and secure it safely and then you can adhere the glue down material to the plywood.

          For the Lucida Surfaces GlueCore Blackrock 22 MIL x 12 in. W x 24 in. L Glue Down Waterproof Vinyl Tile Flooring...Is a vapor barrier recommended when installing on a concrete floor. Thank you.

          1 Answer | 
          Answer This Question

          in order for you to confirm if you need an underlayment you will need to run a moisture test first and then based on the reading you will need to see if the underlayment is necessary. the only recommended underlayment would be a 6mm poly plastics vapor barrier.

                  Worked great in bathroom and foyer!
                  This tile is very heavy duty vinyl, I think it will last for years! I realized early on that staggering was gonna be an issue as the tiles were 12x24 and I had no "square" walls. I highly recommend going with a "stacked " pattern if you are gonna use it in a small space!

                    Loved the pattern/look of faux marble, but wish it would have been available as a floating interlocking planks vs. glue-applied to make the installation easier/less messy. Perfect for our full-bath renovation with retro clawfoot tub.

                    NO problem with item ... Contractor refused to install this tile - because they were more work than ( NOT waterproofed ); "floating tiles" ( that 'pop' every time you step on them . instead !? AVOID "Inaugural Home Improvement ; 169 Williams Rd. Springfield, MA ; 413-628-5177 ' they will rip you off for $25k & leave your project - unfinished !!

                    This Glue Down tile is absolutely excellent, but Home Depot failed to store it properly and will not make good on the damage. Be warned.

                    It is super important that these tiles are 22 mil thick, resilient and waterproof. Others on offer are 6 or 8 mil, and absolutely not worth the money. These tiles are worthy of the time and effort required to install them. Good value.
