Professional All-In-One Tinted Concrete Sealer - Interior & Exterior
Concrete Stain & Seal by Pro Mason Supply is a premium, single-component, water-based aliphatic urethane designed for those who want professional-grade color and protection in a single application. This semi-transparent, pre-tinted formula simplifies the process of finishing concrete by combining a high-performance stain with a rugged, medium-sheen sealer.
Unlike standard clear coats, this product is formulated to enrich the surface with consistent, semi-transparent color while providing a hard-wearing barrier that stands up to heavy traffic and the elements.
Key Performance Features
- Industrial Strength, Water-Based Safety: Get the durability and wear-resistance of a solvent-based system in a user-friendly, low-odor, and low-VOC (under 100g/L) formula.
- Weather & UV Protection: Specifically engineered for both indoor and outdoor environments, displaying superior resistance to UV light, water, alkali, acids, and stains.
- Vapor Permeability: This moisture-tolerant "breathable" coating allows vapor to escape the concrete, preventing the bubbling or delamination often seen with traditional outdoor urethanes.
- Fast Return-to-Service: The quick-dry technology allows for rapid recoating and a faster return to normal use for your driveway or workshop.
- Vertical Protection: Excellent for use on concrete wall surfaces due to its inherent resistance to UV, graffiti, and staining.
Typical Applications
- Residential: Driveways, patios, pool decks, garage floors, and basements.
- Commercial: Warehouses, kennels, restaurant floors, and retail spaces.
- Architectural: Concrete countertops, brick hearths, and decorative micro-toppings.

Pro Tip: Because this is a semi-transparent product, the existing color and porosity of your concrete will influence the final look. We recommend applying in thin, even coats to achieve a deep, professional finish.
Application Instructions
To ensure the highest performance and the most consistent color, Concrete Stain & Seal should be applied following industry best practices for single-component aliphatic water-based urethanes. Proper surface preparation is the most critical step in achieving a long-lasting, professional finish.
1. Surface Preparation
- For New or Unsealed Concrete: Ensure the surface is clean, dry, and free of any debris, oils, or curing compounds. If oil or grease is present, clean thoroughly with a high-quality degreaser and rinse completely. The concrete must be porous enough to "absorb" the stain.
- For Previously Sealed Surfaces: If applying over an existing sealer, the surface must be deglossed to ensure proper adhesion. Lightly sand the entire area with 100–120 grit sandpaper or a sanding screen until the gloss is removed. Thoroughly remove all sanding dust with a vacuum or damp cloth before proceeding.
- Moisture Check: Ensure the concrete is fully dry. While this formula is vapor-permeable, applying over a saturated slab can hinder the initial bond.
2. Application Method
- Stir Well: Before and during use, stir the product thoroughly to ensure the pigments are evenly distributed. Do not shake, as this can introduce air bubbles into the urethane.
- First Coat: Apply a thin, even layer using a high-quality 3/8" nap lint-free roller or an airless sprayer. Avoid "puddling" or heavy buildup, as this is a low-mil (2 mil) system designed for thin, consistent layers.
- Second Coat: For maximum durability and color depth, a second coat is highly recommended. Wait approximately 1 hour (or until the first coat is dry to the touch) before applying the second coat.
- Technique: Work in manageable sections, maintaining a "wet edge" to prevent lap marks. For large outdoor areas, avoid application in direct, mid-day sun to prevent the product from drying too quickly.
3. Clean-Up & Maintenance
- Cleanup: Since this is a water-based system, tools and equipment can be cleaned immediately after use with simple soap and water.
- Maintenance: Once fully cured, the surface can be cleaned with mild, pH-neutral cleaners. Avoid harsh solvents or abrasive scrubbing pads.
Important Application Notes
- Temperature: Apply when surface and air temperatures are between 50°F and 90°F.
- Humidity: High humidity may extend dry times.
- Foot Traffic: The surface is typically ready for light foot traffic in 24 hours. For vehicle traffic (garages/driveways), allow 48–72 hours.
Let customers speak for us
Someone rebuild our concrete steps at the top where they were pulling away from the house, but they did not use black mortar, they did a good job with the craftsmanship, but the mortar looked awful. Thanks to the stain from ProMason our steps look so good!.
The Mortar stain was amazing! Easy to apply and dramatically improved the appearance of our fireplace,. Allowing a DIY correction lof a mismatched, botched professional repair. More color choices would be helpful. Thank you.
I had a problem with the my first order of masonry stain. I was replaced quickly. Great customer service.
The masonry stain is a lifesaver! Love it! Before you freak out over the price it can be dilluted 3x water to stain and do so much coverage. My chaotic multicolor brown brick is now a beautiful warm whitish color. I got the cream masonry stain
I had a chaotic brown, red, cream and gray brick home feom the 70s and wanted to modernize it so I got the cream masonry stain and dilluted it 2x water to stain and did a wash and absolutely love the results. Great product!!!! Would love to show pics?
Great information on the website to select the right mortar for the job I am going to attempt. They also included a print out in the box with further instructions and advice. Fantastic!
Great product! Fast delivery. Ordered on Monday and received on Friday right on time for my weekend project.
I ordered samples for mortar stain, and plan to order gallons of the stain for our project. Ordering was easy and shipping was fast. The stain samples had leaked a little in shipment, but we had plenty to test the stain. The stain itself works perfect and cleans up easily and doesn't have a strong odor, which I was surprised by. I had a question about coverage and reached out to Pro Mason through the contact page. They were quick to respond, helpful and thorough in their reply. Would recommend the products and company to others.
I used the brick stain on two fireplaces. The first one I did using the cream color and it is perfect. For the second one, I used charcoal and it came out a bit dark. (Just like with paint, it starts out light and dries darker.) Because I preferred the color of the wet version of the stain, I decided to go back over it with a paint wash. It was sooooo much harder to do a paint wash! With the stain, it was much easier to get a consistent finish. I am sticking with ProMason for any of my future brick projects!
Really happy to have found this source for good historic masonry repair. I am very happy with the mortar and directions they sent, and their shipping was very fast too. I’m sure I will be a loyal customer for years to come.
Ordered 3 samples of brick stain. I’ve only done a sample of them on a brick yet the coverage on 2 of the 3 was excellent with only one coat with a brush. My middle color was a custom 50/50 mix of the other 2. The 3 rd stain sample didn’t make it to the final brick sampling.
I am entirely new to masonry, but I managed to repoint a section of my 300 year old stone foundation with lime mortar, and I’m very happy with the results. I was not able to find the appropriate mortar locally. Maybe a bit crude, but I bet it’ll hold up another hundred years!
