Review: This primer does not sand without clumping. - This product does not sand without clumping on the sand paper 150-400. It acts like sanding a latex. The product was left to dry over 48 hours in dry conditions with temp 60 - 75 degrees and would not sand smooth without tearing and clumping on sand paper. It is not a good fairing primer for a smooth gloss top coat. Review: Must be thinned - This stuff is great boat primer but wow is it thick...Thinning is a must and if your going to spray it like I did...get the Totalboat spray thinner...Spray it on lightly. ## Features - Totalboat Totalboat Topside Primer (White, Quart) - Brand : Totalboat - Totalboat Totalboat Topside Primer (White, Quart) Brand : Totalboat ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00HS4YY7G | | Brand | TotalBoat | | Brand Name | TotalBoat | | Color Code | #FFFFFF | | Colour | White | | Container Type | Bottle | | Country of Origin | USA | | Coverage | 100 sq ft/quart | | Customer Reviews | 4.4 out of 5 stars 423 Reviews | | Dry Time In Hours | 24 | | Finish Type | Flat | | Included Components | Brush, Roller | | Indoor Outdoor Usage | Outdoor | | Is Waterproof | False | | Item Form | Liquid | | Item Volume | 947 Millilitres | | Manufacturer | TotalBoat | | Model Number | 365387 | | Paint Type | Enamel | | Part Number | 365387 | | Size | 32 Fl Oz (Pack of 1) | | Special Feature | Fast-Drying, High Build | | Special Features | Fast-Drying, High Build | | Specific Uses For Product | Marine primer for one-part and two-part topside paints.

It is a slow cure/dry process and self levels pretty nicely. **Q: Can I use this primer and the topside paint on the hull of a wood and canvas canoe?** A: No. You'll need a flexible paint. Contact TotalBoat and ask if there is an additive you could use. The Automotive world has such an additive for painting the flexible bumper covers with enamel. **Q: Can this product be used on concrete?** A: It probably can, although I would probably choose a product that was intended for concrete **Q: Can it be used on bare cast iron?** A: I really don't know but I would imagine that it would. We used it on bare treadplate and it worked very well - even better than I expected. After one year of heavy use, it still looks good. ## Customer Reviews ### ⭐ This primer does not sand without clumping. *by A***R on 23 April 2026* This product does not sand without clumping on the sand paper 150-400. It acts like sanding a latex. The product was left to dry over 48 hours in dry conditions with temp 60 - 75 degrees and would not sand smooth without tearing and clumping on sand paper.

WOW instant regret!! Difficult to apply is an understatement! Even after thinning it out as stated it seemed to dry instantly! Yet when sanding it to apply the first coat of paint it took almost 2 weeks. In those 2 weeks I attempted to sand and it kept clogging it up. In comparison I didn’t use this primer on another section of the boat and the first coat dried good enough in 48 hours where it wasn’t clogging up the sandpaper. You be the judge. ## Frequently Bought Together - TotalBoat Marine Topside Boat Paint Primer for Fiberglass and Wood, White, 1 Quarts (Pack of 1) - TotalBoat - 365399 Wet Edge Marine Topside Paint for Boats, Fiberglass, and Wood (White, 1 Quarts (Pack of 1)) - TotalBoat Special Brushing Thinner 100 (Quart) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/720861360-totalboat-topside-primer-white-quart](https://www.desertcart.co.uk/products/720861360-totalboat-topside-primer-white-quart) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-31*
