Hello there, paint and primer enthusiasts! You’ve just hit the jackpot of paint estimates: the Pore-Filling Primer Efficiency Estimator Calculator (Or PFPEEC, for those who love a cheeky acronym). Fasten your seatbelts, let’s dive right in!
Introduction
Our treasured PFPEEC formula is as enigmatic as it is splendid. Ready for a magic trick? Here’s the secret formula, in all its glory:
PFPEEC = (Primer Volume / Surface Area) * Porosity
