Buying Guide

Match additive to paint base

Use oil‑based additives like penetration enhancers for oil paints and water‑based additives such as Floetrol for latex and acrylic formulations to avoid compatibility problems

Choose for intended effect

Select flow improvers for smoother brushing or pouring, adhesion promoters for old surfaces, or hardeners/solidifiers for safe disposal of leftover latex paint

Consider concentrated vs ready‑to‑use

Concentrated formulas let you control dosage for spray or pour techniques, while ready‑to‑use products simplify preparation when working on small jobs

Check included accessories

Some kits include mixing sticks or small dispensing formats that help with proper mixing and disposal; these reduce the need for extra tools

Compare coverage and mix ratios

Review manufacturer mix ratios and recommended addition rates to estimate how much additive you need for a given bucket or gallon of paint
