If properly formulated, is there an advantage to using spray or brush grade polyurethane coatings? I understand that they both bond to existing coatings by mechanical and not chemical means.
I was informed that the spray grade is less viscous and because of the spray pressure that it bonds to the mechanical roughened adjacent surface better. Is this correct?
thanks, Dik
