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
Came out beautiful and better than I had hoped
Shipped quickly. Arrived quickly. It mixed easily and adhered to my spalling bricks. So far so good.
The perfect mortar for 126 year old bricks (granite boulder and brick foundation built in 1900). Very happy with the mortar and clear instructions. Thank you ProMason!
Worked perfectly. Stain changed color of existing brick to the tone I was expecting giving it new life and blends with other new finishes.
I haven't had a chance to mix and use the mortar yet. However, the customer service is great. They immediately sent a replacement package of colorant since the original had leaked.
Our project turned out wonderful! What an amazing difference. It completely changed the look of the house!!
Easier to apply than I anticipated.
My first time staining brick and I was nervous on how it might turn out because I was going from dark brown tone bricks to gray tone (before and after photo submitted)Blended my own color combo and It looks amazing.
The stain covers well and a quart did a good amount of surface area. The perfect shade was achieved by mixing 2 colors. It looks great and is a nice brick border update!
The masonry sealer worked great. It was easy to apply and dried perfectly.
So far, so good. It will take time.
I just tried the mortar out. Need to learn a little more about using it as what I applies turned white. Yes it was sunny and hot. I tried keeping it spritzed and ended up shading the work with tarps, but too late. I’ll try again next week since I see a cloudy day in the forecast. Marie
We took down the Wood pan line in our old home. Built in 1880. All the room is red brick. Except for this one spot that it looks like they ran out. Using pro Mason stains, I was able to make coordinate better with the rest of the room. Very happy with the results! It would have been impossible to achieve without being able to dilute and combine the stains to make multiple colors to match the variants in the original bricks.
Working out great so far
This was awesome. It mixed very well, and even though its still curing, it is very hard now. It was also fun to mix up a mortar by hand the same way they used to do back in the day.
I had my steps repointed but they were way to light and slot of cement left on the brick. These stains worked amazing. Darkened the mortar and made the bricks look new!! Love this product! I used dark buff for the mortar and mixed burgundy and dark red for my brick.
