AggreSeal-Pure is a special PURE ACRYLIC version of Surfkoat's famous 30% solids AggreSeal Sealer specially designed and produced for our exposed aggregate customers. AggreSeal-Pure offers deep color enhancement and a rich Wet Look with a high-gloss finish. AggreSeal-Pure is also a great choice for many other applications where a 30% premium pure acrylic is desired. AggreSeal-Pure is available in a clear or brown tinted formula to compliment and enhance all types of exposed aggregate or pea gravel concrete.
AggreSeal-Pure is 100% pure acrylic, unlike the original styrene-acrylic version of AggreSeal. That means added durability and a product that will never yellow from UV exposure like other "contractor grade" styrene-acrylic aggregate sealers. Pure acrylics should only be applied to concrete that is fully cured (28+ days). AggreSeal-Pure is our #1 best selling aggregate sealer, and the choice of all our professional contractors.
What's up with all these acrylics? What's the freaking difference? Which is right for me?
As you search for the "perfect sealer" you will likely come across hundreds of solvent-based acrylics, all in a different shiny can, and all claiming to be the "best sealer ever invented". Truth is, there are only a few basic differences in solvent-based acrylics that are even noticeable to the average user. Many (if not most) are the EXACT same products private labeled over and over with new claims to fame. Here are the three basic things you should be looking at when choosing a solvent-based acrylic:
Acrylic Formula - Pure Acrylic or Co-polymer? Pure acrylics are typically a little more durable than co-polymer (styrene-acrylics) and will not yellow with UV exposure. Pure acrylics should only be applied to cured concrete (28+ days old). Styrene-Acrylics are often referred to as "cure and seals since they can be applied to freshly poured concrete. The addition of styrene into the formula allows for a bit of breathability. Because of this, styrene-acrylics are a little more forgiving if you apply them over concrete that has a higher moisture content. Unfortunately, they typically don't last as long and most will "yellow" to some degree over time with UV exposure, no matter what the manufacturer says.
Solids Ratio - This is simply the ratio of acrylic to solvent in the product. The most common ratios are 25% and 30%. Simply put, 25% products contain 5% less solids than 30% products. This means a 25% product is a bit thinner, penetrates deeper and is sprayable. Usually both produce the same gloss finish, but because the 25% leaves a thinner film and penetrates deeper, it appears more of a semi-gloss than a 30%. It has been our experience that 25% products will consistently outperform 30% products due to their superior penetration. Thinner films are also less likely to flake, peel or chip than thicker films. The exception is exposed aggregate where a thicker product is often needed due to the additional texture and porosity.
VOC content - This has to do with the types of solvents that are used in the formula. Many local, state and regional laws now regulate the amount of VOC's a product can emit. This means "low VOC" formulas usually contain higher levels of "exempt" solvents like acetone and butyl-acetates. For the most part this does not change the quality of the product, but it does affect the drying speed. Typically "low VOC" solvents evaporate more quickly, which gives the sealer less time to penetrate and/or bond to an existing coating. Delamination is a big problem with low VOC solvent-based acrylics when applied in hot temps or direct sunlight.
So.... If you are looking for a solvent-based acrylic, consider the attributes of each and make the best decision for your situation based on facts, not brand, packaging, marketing or online sealer review sites just trying to market the products they sell.

AggreSeal-Pure is our best solvent based 30% solids pure acrylic sealer specifically designed for sealing exposed aggregate concrete. Exposed aggregate is also referred to as pea gravel concrete, pebble concrete and exposed chip concrete. AggreSeal-Pure offers deep color enhancement and a rich Wet Look with a high-gloss finish. AggreSeal-Pure is is available in both a clear and brown tinted formula. The brown tint is subtle and transparent, not over powering. The tint is designed to darken and enhance the natural colors of brown pea gravel.
AggreSeal-Pure, along with most solvent-based acrylics, is compatible with many other similar solvent-based acrylics that may already exist on previously sealed concrete. Solvent-based acrylics should never be applied over any existing water-based sealer. If your concrete has an existing water-based sealer, it must be removed before applying AggreSeal-Pure. If you have an existing water-based sealer or a "Mystery Sealer", you may also consider other products like Seal-n-Lock SuperWet, which can be applied over many compatible water-based sealers as well as most solvent-based sealers.
Cleaning and Preparation Instructions
1. Completely remove all oils and contaminates from the surface. All previous sealers or coatings must be removed before application unless they are a compatible solvent-based acrylic. Use only cleaning methods suitable for the substrate you are cleaning. Clean oily concrete with our Concrete Degreaser. Use a bristle brush for heavily oiled spots. Area to be treated must be clean, porous and sound.
2. Use only the amount of cleaners necessary to remove contaminates, oils, fluids and sealers from the substrate. If using acidic cleaners to etch surface or to remove efflorescence, calcium, rust, etc, be sure to neutralize and restore pH with Balance Neutralizer. Rinse thoroughly! Surface and pores must be clean, dry and free of all chemicals before applying AggreSeal-Pure.
3. If using over cured trowel finished concrete, diamond grinding is always recommended to open the surface and allow adhesion of the sealer. Do not grind finer than 100 grit. Beyond 100 grit, sealer adhesion will be compromised. Dry grinding is highly recommended to avoid introduction of moisture into the concrete. If diamond grinding is not possible, first etch with Surf-Prep.
4. Allow area to dry completely.
Always test in an inconspicuous area before use to ensure compatibility and desired results!
For best results apply by roller. Use a long nap roller for exposed aggregate, a medium nap roller for textured surfaces and a short nap roller for smooth surfaces. A brush may be used to apply to edges and expansion joints where a roller can't reach. Do not allow to Puddle! Thick or puddled areas may prevent the solvent from evaporating and may be susceptible to moisture intrusion which may cause milky white spots. Applying too thin may cause sealer to prematurely delaminate, flake or wear away. Allow sealer to dry for 24 hours for light traffic and at least 48 hours for heavy traffic. If applying two coats, wait approximately 4 – 6 hours between coats. Do not thin product.
Make sure all sprinklers are turned off for a 24 hour period of time. Apply AggreSeal-Pure only if rain is not expected for at least 24 hours. Do not apply AggreSeal-Pure if surface temperature is below 40° F., or above 80° F. If possible always apply as concrete is cooling, rather than as concrete is warming. Warming by the sun causes the air inside the concrete to expand and push out through the surface, often causing bubbles in the still wet sealer.
MATTE FINISH ADDITIVE: If a low gloss, matte or satin finish is desired, Matte-50 Matting Additive can be added to create the exact gloss level you desire. Follow directions on Matte-50 for mixing instructions. For most consistent results, add Matte-50 to both coats.
COLOR ADDITIVE: If a tinted or colored sealer (other than our standard brown tint) is desired, AcrylPack Color Tint can be added to create beautiful transparent or solid colors. Follow directions on AcrylPack for mixing instructions. For most consistent results, add color to both coats.
SLIP RESISTANCE: Surf-Grip may be used for additional slip resistance. Follow directions on Surf-Grip and do not overload system. When using a non-skid additive, do not add to first coat. Add it to second coat. All non-skid additives shorten the life of the film to some degree.
CLEAN UP: Clean up tools with A1 Solvent or Xylene.
Of course, having the right tools will make your job easier, so scroll to the bottom to see our recommended Sprayers, Rollers and Application Tools!
Coverage Rates: Coverage rates are approximate and will vary depending on substrate density, porosity and temperature. Product is typically applied in a single heavy coat on aggregate, and in two thinner coats for all other surfaces. Coverage rates based on total application.
Exposed Aggregate: 100 sq. ft. / gallon
Stamped concrete: 200-250 sq. ft. / gallon
Broom swept concrete: 150-200 sq. ft. / gallon
Troweled concrete: 200-250 sq. ft. / gallon
Like all things, maintaining optimal protection of a sealed surface requires scheduled maintenance. Once properly applied, surfaces sealed with AggreSeal-Pure may periodically require a light cleaning to remove dirt, dust, mud, etc. In most cases, low pressure water is all that is needed for routine cleaning. Do not use a hot-water pressure washer unless you are preparing to apply a maintenance coat of AggreSeal-Pure. Re-seal surface every two years or as needed to prevent buildup of sealer.
