Hi,
I have a question about floor prep.
We have decide to install the hybrid floor in our bedrooms, so we removed the carpet in one of our bedrooms to check if the floor is even. However, we found adhesives on the cement floor ( please see the image below). We would like to just cover it up with self levelling compound. Room size is about 3 m x 3 m. What are your thought?
We are by the way DIY beginners

. Thank you
