PRODUCT DESCRIPTION: Trojan Masonry Sealer is a penetrating masonry and concrete sealer that includes a proprietary water-based polyester polymer. Once dry, the polyester polymer forms a barrier that completely fills the voids and solidifies the substrate. Although its named Trojan Masonry Sealer, it can be used on most any porous surface.

Brick Sealer - Trojan can densify the brick or paver, thereby increasing its strength and future durability. As it is not a topical sealant, Trojan will not be slippery nor change the look of the surface, yet permanently protect against water or oil/contaminants from absorbing.

Concrete Sealer - Concrete is very porous and subject to 'freeze thaw' conditions in winter climates. Whereby water freezes in the pores during the evening and then thaws out during the day. This constant contraction/expansion helps 'spall' (chip/fragment/flake) concrete. Even in warmer climates, weather, abrasion and contaminants will weaken the substrate over time. Trojan will permanently fill the pores to help prevent future spalling/deterioration and provide easier maintenance of the surface. Its like poring liquid plastic into your concrete.

Driveway Sealer - Deicing chemicals and salts that cars track in from the highways are highly corrosive to concrete. Over time those chemicals will pit the surface. The natural abrasion of driving on concrete, weathering and car fluids that leak into the substrate also take their toll. Trojan will strengthen and provide stain resistance, yet unlike topical sealants will not wear away or provide 'hot tire pick-up' (hot tires melt surface coatings like acrylic sealers and then peal them up). 

Stone Sealer - Limestone for example is extremely porous and soft. Trojan will harden the stone but also not change the natural look of the surface.

TYPICAL USES: For industrial, commercial and residential use on concrete, brick, stucco, porous stones and all masonry. Can be used on horizontal and vertical surfaces such as homes, buildings, chimneys, sidewalks, driveways, basements, roads, floors, bridge decks, parking lot structures and patios. 


Remarkably s

uperior to other sealers because it seals and protects from within. As Trojan does not contain any solvents, it is non-toxic, non-flammable, non-caustic and has low VOC. It will not react with anything and can be safely used indoors as well as outside.

Trojan penetrates into the concrete or masonry 2 - 4 inches and provides a paintable surface. Authorized by USDA for use in federally inspected meat and poultry farms. 

15 Year Waterproofing Warranty - We offer this warranty, because our company has been making Trojan Masonry Sealer for over 15 years. Therefore our product has withstood a 'real world' test of time under extreme heat/cold and weather conditions.

ENVIRONMENTAL QUALIFICATIONSTrojan Masonry Sealer provides LEED (Leadership in Energy and Environmental Design) credits toward LEED Certification for Green Building projects by promoting Indoor Environmental Quality (IEQ).

IEQ Credit 3 - Construction - Indoor Air Quality (IAQ) Management Plan

IEQ Credit 4 - Low Emitting Materials

QUALITY CONTROL TESTS: Trojan Masonry Sealer has passed nine independently performed quality tests per the American Society for Testing and Materials (ASTM), Australian Standard (AS) and NCHRP specifications. These tests include:

ASTM 413 Water Absorption of Chemical Resistant Concrete/Masonry.Tested the effectiveness of Trojan Masonry Sealer in resisting water penetration. Trojan was applied in 1994 on one of Coca Cola Company’s major exposed concrete roof-top parking structures.

In 1997, three years after application, Coca Cola hired independent laboratory, H.C. Nutting Company to perform the ASTM 413 test. Test results revealed an “excellent” performance in the waterproofing ability of Trojan as it proved that there was no penetration of water from the core samples of the concrete deck.

ASTM C140 “Masonry Absorption Test for Light Weight Block”. Trojan Masonry Sealer was applied to light weight block and weighed in its dry state. The block was then placed in water for 2 days. Afterwards it was weighed again while still wet. The 2-day test results are as follows:

Sample No.
Dry Weight
Wet Weight
Percentage Absorption
28.56 LBS.
28.72 LBS.
28.68 LBS.
28.78 LBS.

ASTM requires that water absorption cannot exceed 1% after 2 days of immersion. The results prove that Trojan Masonry Sealer far surpassed these requirements.

ASTM 123D - “Penetration Test for Nuclear Power Plant, 8000 psi Concrete Pour”. This test was performed by Pittsburgh, Plate and Glass subsidiary, Keeler & Long to determine the penetration of Trojan Masonry Sealer on a Nuclear Plant slab that was 8000 psi pour.

Six months after Trojan was applied, the ASTM-123D test was performed by taking two 2” core samples. After diamond sawing the cores in half, the test revealed that the Trojan penetrated 2 inches. As the normal pore for a concrete slab is 3000 to 4000 psi in density, Trojan can easily penetrate 2 to 4 inches on regular concrete.

Blue Dye Test - “Blue Dye Absorption Test”. Independent laboratory, H.C. Nutting Company conducted a Blue Dye Test for the Department of Public Works of Cincinnati, Ohio at the Garfield Garage parking deck. Trojan was applied to the concrete surface along with several other sealers. Afterwards, two 1” diameter cores approximately 2” long were extracted from each test site of the concrete parking deck. The objective of the test was to determine to what extent the blue dye was absorbed if any. Trojan was top rated as “excellent” at not allowing the blue dye to penetrate the concrete surface.

ASTM 642-82 - “Masonry Absorption Test for Brick”. Independent laboratory, H.C. Nutting Company coated a brick with Trojan Masonry Sealer and then submerged the test brick in water for 48 hours. The objective of the test was to determine water absorption of the brick by establishing its weight when dry before being submerged and again weighing the test brick immediately after its 48 hour water submersion. The results showed no weight increase of the brick after it was taken out of the water, thus proving that Trojan provided total waterproofing of the brick by not allowing water to be absorbed.

ASTM C672 - “Scaling Resistance”. Independent laboratory, H.C. Nutting Company completed the scaling resistance test on treated concrete after applying Trojan Masonry Sealer. Test results showed that there was no scaling after 100 weathering cycles (via mechanical brush) on the concrete that was sealed with Trojan as opposed to severe scaling on untreated samples of the concrete.

AS 1012.21-1999 - "Water Absorption of Hardened Concrete". Determination of water absorption and apparent volume of permeable voids in hardened concrete. Trojan Masonry Sealer passed this standard by not allowing water absorption.

NCHRP 244 – Cube Test – “Accelerated Weathering Test”. Trojan Masonry Sealer surpassed the standard of not exceeding 25% of untreated cube absorbed chloride.

NCHRP 244 – Southern Exposure – “Chloride Ion Penetration Test”. Trojan Masonry Sealer did not allow chloride penetration and thus passed absorbed chloride requirements not to exceed 10% of untreated concrete.
