Hi, I am planning to install spc flooring in my bedroom (~11m^2). After removing the old carpet and tack strip, there are chips/holes from the tack strip nail as picture below.
My question is that is it ok to lay spc plank with 1.5mm ixpe underlay on top of the concrete surface?
or do I have to patch the holes?
or is self leveling concrete a MUST in this situation? The overal floor surface is pretty flat without any big bumps.
Hello @adamliaw
Welcome to the Bunnings Workshop community. It's marvellous to have you join us, and thank you for sharing your question about repairing carpet tack strip damage.
If you wish to check that your cement floor is level, I suggest using a large spirit level to make sure that the concrete floor is totally flat. I would only recommend using self-levelling concrete if there is a severe dip or uneven spot in the concrete flooring.
Once you have checked that the floor is level, it's ok to start laying down the underlay and floating floor set. However, before you begin, I suggest giving the floor a thorough clean up with a broom and a vacuum cleaner. This will remove any dirt and debris that might have settled on the concrete floor.
If you are worried about the damage on the concrete floor, I propose filling it in with Parfix 1kg Ready To Use Multipurpose Filler. Your goal is to have it as close to level as possible so that you'll have to do very little sanding. It's better to patch the damage rather than having to discover that the holes have affected your floorings level.
I also suggest having a look at this discussion - How to prepare for floating floor? by @mich1972.
If you have any other questions we can help with, please let us know.
