Agree. I was hoping to get some information on which sealer is best for different applications. All I learned is that there's solvent based sealers and water based sealers.

No problem Tony, we're trying our hardest to educate people on the industry and information that people aren't necessarily aware about. thanks for your positive comment.

We regret to learn about your current situation. It is essential to address the matter by ensuring a secure substrate, achieved through either establishing a solid foundation or incorporating a render or screed onto the floor. Although we haven't personally assessed the project, there is a potential need to consider the removal of the existing tiles and initiating the process anew. We empathise with your challenge and sincerely hope for a resolution that minimises any undue distress.
