Quick Overview

NAPCO Fast Reducer - Use with our 4-Hour Mega Fast Resins

* Required Fields

Prices start at


Our Fast Thinner is blended to decrease the time required for evaporation. When a solvent evaporates too slowly, the chance of runs and sags in the final finish increases.

NAPCO's Fast Thinner is ideal for use during the colder months of the year or in cooler climes. Like our All Purpose Thinner, it is a blend of extra pure thinners, contains no water and is used to thin all Poly-Glass topcoats and Epoxy Primers. It is formulated to help provide maximum gloss and dry quickly in cold conditions.

Use NAPCO's Fast Reducer with our Mega Fast 4-Hour High Gloss and Mega Fast 4-hour Low Gloss resin.
