Can you put a clear polyurethane as a sealer over vinyl floor planks?

by Cas

I’m planning on laying 3mm vinyl floor planks timber look, over a concrete floor with the supplied glue. I don’t think they are tongue and groove. They will just butt up against each other. My worry is, would edges curl up over time ? So my thought was to put a few coats of clear poly over the top to secure peices don’t move over time. As the area is my downstairs tv and kitchen area.

Anyone have any experience with these types of vinyl floor planks ? Or has anyone sealed over this type of flooring and their experience?

    I would choose a different flooring that will lock together and does not have to be glued down. That kind of flooring would never curl up and you would not have to cover it with poly. Also--if you are using a "3mm" flooring this is not a good quality flooring as the top wear coat is very thin and if your area gets a lot of use it may not wear well for a long time. I used a less expensive flooring like this in a walk in closet off my dining room that gets a lot of traffic in and out and it has scratched and dulled over time. It works fine for the closet but I would not install it in any room that is used frequently. Yes--I am sure your flooring was a less expensive option but if you have to add the cost of poly and what you would need to apply the poly you could apply that money to different flooring.

    Yes I understand what your saying but these planks were advertised as ‘industrial’ flooring so I’m presuming they are manufactured for high traffic purposes.

    The poly I’m able to get as I was in that industry and have contacts.

    Yes it comes down to the cost as $350 for all materials for 36.5 square meters I’m thinking it’s better than paint.

    i have concrete floors and have just painted them with White House paint.

    why would products b sold with recommended glue if knowing they’d lift ?

    Still not sure what to do ?

    If they are glue down and you follow the directions properly they shouldn't curl, especially if the are suggested for industrial use, however, read all the small print on the label before purchasing, sometimes the advertizing is made so when you read it, its gives a certain impression, not necessarily the correct one. I would also not bother with the poly, it will only give you added wear and will dull over time and may create other problems down the road. I put in the cheapest click laminate in my basement years ago when it first came out, it has stood the test of time and looked brand new when we sold couple of years ago.

    Also my daughter put in the vinyl plank flooring through out her new home, it was glue down, 5 years later no lifting. She loves it so easy to keep mopped.

    Thank you

    I have them at my place and I’m so glad I got them. Great quality and beautiful colours. I will send a photo once I’ve actually laid them.

    I have vinyl plank flooring on our front porch. The tracked in wetness has caused it to be compromised and curl. Unsure if the poly would help if a high traffic area. It might, you could expect to see the sealant wearing through.
