Do you need to sand before applying Osmo?
Hello there, I have a question regarding the process of applying Osmo to a surface. Is it absolutely necessary to SAND the surface beforehand? I've heard that sanding can help improve adhesion, but I'm not sure if it's a crucial step. Could you please clarify the importance of sanding and whether it's a prerequisite for applying Osmo successfully? Also, if sanding is not necessary, could you suggest any alternative methods to ensure proper adhesion? Thank you in advance for your help!
