⚡ CalcWolf Insight

The single biggest staining mistake: not cleaning and prepping the surface. Stain applied over dirt, mildew, or old flaking stain will peel within a year. Power wash, let dry completely (48+ hours), and sand smooth before staining. Prep is 70% of the job — the actual staining is the easy part.
