Heated bed or cold bed? Either way aside from replacing the actual plate I'd recommend applying one of these: https://www.amazon.com/dp/B077KDCRL5/ref=cm_sw_r_cp_apa_glt_fabc_SJQ8WQY87X5T11BW32SS https://www.amazon.com/dp/B077KDD8P6/ref=cm_sw_r_cp_apa_glt_fabc_F3SRJJ02EMG8Q9155CDX
One is for a hot surface, the other for a cold surface. GeckoTek is fantastic for a build surface, you don't have to use any other method of adhesion so say goodbye to glue, hairspray, tape, etc. If you're careful the GeckoTek is good for a lot of builds before it needs replacing.
