## Overview

TotalBoat Marine Topside Boat Paint Primer is a premium, one-part marine primer designed for above-waterline use on fiberglass, wood, gelcoat, and painted surfaces. Offering excellent coverage of 85-100 sq ft per quart, it dries fast within 60-90 minutes and cures to a smooth, sandable finish. Compatible with all 1- and 2-part polyurethane and enamel topside paints, this chromate- and lead-free primer ensures durable, flexible protection against marine wear while being easy to apply by brush, roller, or spray. Available in gray and white, it’s the trusted choice for professionals and enthusiasts aiming for a flawless, long-lasting marine paint job.

## Description

To ensure the topside paint on your boat adheres well and won't lift or peel, apply TotalBoat Topside Primer first. This one-part premium marine undercoat is compatible with all 1- and 2-part polyurethane and enamel topside paints. Its high-solids formula flows easily, requires only one coat, dries quickly, and is easy to sand. Perfect for priming decks and hulls above the waterline before applying a topside hull paint, such as Total Boat Wet Edge, or a non-skid marine deck paint, such as TotalBoat Total Tread. Topside Primer is easy to apply by brushing, rolling, or spraying on properly prepared wood, fiberglass, gel coat and previously painted surfaces in good condition. Because of the high solids content, it's important to stir this primer for a full five minutes before applying, to ensure it's mixed thoroughly. If needed, thin with TotalBoat Special Brushing Thinner 100 when brushing, and xylene when spraying. As for application tools, we recommend the following: Brush Application - natural bristle brush; Roller Application - 1/8" solvent-safe foam roller cover; Spray Application - 1.1mm spray tip. Most applications will require only one coat. It's not necessary to achieve full hide from Topside Primer, and additional coats should not be applied to achieve full hide. It's more important to have a thin, consistent coat. If a second coat is needed, sand lightly with 220-grit sandpaper and remove any sanding residue with a clean, dry lint-free rag or vacuum. Choose white or gray in quart or gallon sizes. TotalBoat Topside Paint Primer provides excellent coverage, requires fewer coats, dries faster, and is more flexible than other one-part marine-grade primers. Compare to Rustoleum Marine Paint Primer, Pettit Easypoxy Topside Paint Undercoater and Interlux Pre-Kote Primer. All TotalBoat products are formulated to provide great value and great results. 100% made in the USA.

Review: Very good boat primer. - Dries fast and even. Good base for the overcoat.
Review: Works good quality i’m a female easy to use for me - This is some of my favorite paint. I’ve used on my boat two years in a row, my boat’s older and gets a lot of foot traffic on it although it did come a little damage last time I received it. I’m not sure that it lasted for years and years unless you take your old paint down really low.

### ⭐⭐⭐⭐⭐ Very good boat primer.
*by E***C on February 11, 2026*

Dries fast and even. Good base for the overcoat.

### ⭐⭐⭐⭐⭐ Works good quality i’m a female easy to use for me
*by S***F on November 3, 2025*

### ⭐⭐⭐⭐⭐ best primer
*by K***. on February 9, 2025*

after reading some negative reviews i contacted the distributor to find out about the product. with that conversation i decided to buy the primer, paint and thinner. i did 2 test spots with the paint and primer to make sure it performed as it should. The paint took about 15 hours to dry and the primer only a couple hrs. I have a 16 ft center console i am painting the inside , by the time i was finished the the beginning was dry to touch. The primer is thinner than the paint so i choose not to thin it out. i rolled a thin coat with a foam roller coverage was good with one coat but will likely do a quick 2nd coat just to be safe. do worry about the negative reviews, follow the directions and you will have no problems. i have my garage heated to about 68 degrees also
