DIYers and contractors struggle to get construction adhesive to bond properly on painted surfaces

People attempting home repairs and construction projects face adhesive failure when applying grab adhesive over existing paint, resulting in wasted materials, project delays, and structural failures. Current adhesive products don't provide clear guidance on surface preparation for painted surfaces, forcing users to troubleshoot through trial-and-error or abandon projects. This is particularly painful because the adhesive cost is wasted and the underlying problem (poor bonding) isn't obvious until after application.
