About Product Overview

KILZ PRIMR 5G LTX is a water-based acrylic primer built to block stains before they bleed through your topcoat, whether you're covering water marks, smoke damage, or old paint on interior or exterior surfaces. The 5-gallon container covers 1,500 to 2,000 square feet, making it a practical choice for whole-room or whole-house jobs where buying by the gallon would mean too many trips back to restock. It goes on with a brush, roller, or sprayer and cleans up with just water, so there's no solvent to deal with when you're done for the day. Recoat in as little as an hour, and it's tintable if you want to get a jump on your finish color. The flat white finish also resists mildew, which matters in bathrooms, basements, and other damp spots.

  • Water-based acrylic formula with stain-blocking performance
  • 5-gallon container covers 1,500-2,000 sq. ft.
  • Works on all surfaces, indoors and outdoors
  • Recoat in 1 hour; full cure in 7 days
  • Tintable, flat white, mildew-resistant finish
  • Backed by a limited lifetime warranty

Price check

Go ahead. Check.

You're going to price-check us against Amazon, Home Depot, and Lowe's. Everybody does. Good — open all three tabs. We'll wait. Then look hard at what you're actually being handed over there.

On Amazon, start with these four questions before you click buy.

01

Who's actually selling it

The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.

02

Whether the warranty survives

Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Kilz. A third-party marketplace seller usually isn't.

03

Where the box came from

Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.

04

Who you call when it breaks

Ours is a phone number with a person behind it who has held this product. M–F, 6 AM – 5 PM Pacific. (866) 469-8556

The big boxes don't care if your hardware store survives.

Amazon, Home Depot, and Lowe's are built to pull every hardware dollar out of your town. When the local shop can't keep the lights on, the counter where somebody actually knew which part you needed goes with it. We're built the other way: real brands so you're never stuck on a marketplace, and a straight answer to buy it down the street when that's the better call. Support independent hardware — it doesn't restock itself.

Why we tell you to shop local

Shop Local · Support Independent

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
