SIP-1133™ PCC Seal
SIP-1133™
Protect sound concrete before water, salt, and freeze-thaw damage become expensive repairs.
Apply SIP-1133™ as soon as 30 days after the pour, or according to the installer's curing guidance, then reapply every 3–5 years.
The best time to seal concrete is immediately after it has cured enough for treatment. The second-best time is today, while the surface is still sound. SIP-1133™ is a water-based, soy-derived penetrating sealer backed by third-party freeze-thaw and salt-scaling comparisons.

WHY CONCRETE PRESERVATION MATTERS
Seal concrete while there is still something worth preserving.
New concrete can receive its first SIP-1133™ treatment as soon as 30 days after the pour, or when the installer's curing guidance allows. Existing concrete does not need to wait for a future project cycle. If it is sound, clean, dry, and able to absorb a penetrating treatment, today is the right time to put preservation on the schedule.
Reapply every 3–5 years to keep preservation in the maintenance plan. Heavy traffic, aggressive deicing-salt exposure, cleaning practices, and surface wear can justify checking the surface sooner.
Those field studies evaluated other sealer chemistries, not SIP-1133™, and do not establish a SIP-1133™ service life. The CMT and Iowa State results below address the product-specific laboratory evidence. Deep spalls, active structural cracking, failed joints, drainage problems, or crumbling concrete still need repair before sealing.

FREEZE-THAW AND SALT-SCALING STUDIES
Tested against untreated concrete.
Construction Materials Testing is a Des Moines laboratory founded in 2001. CMT specializes in Portland cement concrete testing and publishes AASHTO, CCRL, and U.S. Army Corps of Engineers laboratory accreditations. For Project 261121SOY, CMT prepared the concrete specimens, ran the freeze-thaw chamber, recorded the measurements, and issued the report.
Relative dynamic modulus
82.21% at 120 cyclesA tested 22.5% SIP-1133™ development series had the highest observed average RDM among all five groups at 120 cycles. Both tested SIP formulations delayed their steepest observed 30-cycle modulus loss until the 120–150-cycle interval.
Mass-loss comparison
42.9% less vs. untreatedAt 180 cycles, a separate SIP-1133™ development series recorded 4.55% mass loss versus 7.96% for the untreated control, a 42.9% reduction calculated by SoyLei.
Iowa State PCC scaling study
15 to 21+ cyclesIn internal testing conducted at Iowa State University, untreated specimens failed after one to three cycles. SIP-1133™ treated specimens lasted fifteen to more than twenty-one cycles; at eighteen cycles, two showed no visible scaling and one showed minor scaling.
CMT describes its work as conducted in general accordance with ASTM C666. Each CMT group contained three specimens; the curve analysis is descriptive and does not establish statistical superiority or an exact field-life forecast. The Iowa State study used three untreated and three treated specimens with modified specimen geometry.
A PRACTICAL PRESERVATION SCHEDULE
Seal after cure. Reapply every 3–5 years.
Plan the first application as soon as 30 days after the pour, or according to the installer's curing guidance. For existing sound concrete, the next good application window is the one you can schedule now.
Check whether the concrete is a candidate
Look for sound, absorbent concrete without serious spalling, active structural cracking, failed joints, or unresolved drainage. Identify prior sealers or coatings that could block penetration.
Choose the first application window
New concrete can be treated as soon as 30 days post-pour, or when the installer's curing guidance allows. Older concrete can be treated after needed repairs and surface preparation.
Prepare and apply
Clean and dry the surface, confirm temperatures are 40°F and rising with no rain expected, protect adjacent areas, and follow the current coverage and spray instructions.
Put resealing on the calendar
Reapply every 3–5 years. Check high-traffic or salt-exposed surfaces sooner, and address damage before the next treatment.
SIP-1133™ is supplied as a 1:2 concentrate. Add two gallons of water to one gallon of concentrate to make three gallons of ready-to-apply treatment. Apply the diluted treatment at one gallon per 40 square yards (360 square feet). One gallon of concentrate therefore treats 120 square yards (1,080 square feet) when properly diluted. The current brochure, label, SDS, project specification, weather, and site controls govern the work.

The Science
SIP-1133™ combines product-specific laboratory testing, university testing, patented biobased chemistry, and long-term field research on concrete-sealer maintenance. Each source answers a different question, and the evidence guide keeps those claims separate.
- Demonstrated freeze-thaw protection In independent CMT testing, a SIP-1133™ development formulation recorded 42.9% less mass loss than untreated concrete after 180 freeze-thaw cycles. A second tested formulation retained the highest average relative dynamic modulus among the five groups at 120 cycles.
- University-tested performance SIP-1133™ was evaluated in Iowa State University’s CCEE Structures Laboratory in 2021 under Professor Christopher Williams. The evidence guide explains the internal test program and results.
- USPTO-examined innovation U.S. Patent No. 12,297,150 covers the AESO technology used in SIP-1133™. Before issuing the patent, the USPTO examined the claimed invention for utility, novelty, and non-obviousness.
- Biobased chemistry with easier handling SIP-1133™ uses soybean-oil-derived AESO, a biodegradable active ingredient that showed low toxicity in in vitro studies. The finished water-based product's current SDS reports a 599°F flash point, no odor, and non-dangerous-goods status for DOT transport—a markedly simpler fire and vapor-control profile than traditional silane-based sealers.

BUYING, TIMING, AND APPLICATION QUESTIONS
SIP-1133™ FAQ
Is my concrete a good candidate for SIP-1133™?
Start with sound Portland cement concrete that can absorb a penetrating treatment. The surface should be clean and dry, with serious spalling, active structural cracking, failed joints, and drainage problems repaired first. Identify any existing sealer or coating because it may block penetration. A small test area can confirm absorption and finished appearance before full application.
When should SIP-1133™ first be applied to new concrete?
Plan the first application as soon as 30 days after the pour, or according to the installer's curing guidance. The goal is to begin preservation after the concrete is ready to accept treatment and before repeated water, salt, and freeze-thaw exposure.
Is it too late to seal older concrete?
Not if the concrete is still sound and able to absorb the treatment. The best time to seal is immediately after cure. The second-best time is today, before serious damage occurs. Clean the surface, make needed repairs, check prior treatments, and confirm candidacy before application.
How often should SIP-1133™ be reapplied?
Reapply every 3–5 years. Heavy traffic, frequent deicing-salt exposure, aggressive cleaning, or visible surface wear can justify checking the concrete sooner. Repair damage and prepare the surface before each treatment.
Do I need SoyLei to inspect my concrete first?
Most projects do not require an on-site SoyLei inspection. Use the candidacy checks on this page, the current application brochure, and the installer's guidance. SoyLei can provide current product requirements and support a special review for very large, unusual, or specification-driven projects.
Can I buy SIP-1133™ directly from SoyLei?
Yes. SIP-1133™ is available directly from SoyLei now; an Amazon listing is not required. Order the quantity you need, or ask us for help estimating coverage or planning a larger or unusual project.
How much SIP-1133™ should I plan for?
SIP-1133™ is supplied as a 1:2 concentrate. Add two gallons of water to one gallon of concentrate to make three gallons of ready-to-apply treatment. Apply the diluted treatment at one gallon per 40 square yards (360 square feet). One gallon of concentrate treats 120 square yards (1,080 square feet) when properly diluted. Allow for surface texture, porosity, test areas, equipment, and project waste before ordering.
How soon can treated concrete return to service?
SIP-1133™ is designed for traffic return in about one hour after application. Weather, porosity, application rate, and site conditions can change drying time. Follow the current instructions and verify surface condition and friction before reopening.
Can a pressure-washing, soft-washing, or roof-preservation business offer SIP-1133™?
Yes, eligible exterior concrete can become a separate service after cleaning. Build the offer around candidacy, preparation, controlled spraying, documented coverage, and a 3–5-year maintenance conversation. SIP-1133™ is made for concrete, not roofs.
Does SIP-1133™ repair damaged concrete?
No. SIP-1133™ is a maintenance sealer, not a crack filler, patch, joint repair, or structural treatment. Complete necessary repairs and correct drainage problems before application.
How does the handling profile compare with a silane sealer?
Commercial products vary. In one current manufacturer comparison, the SDS for 99% active Sikagard®-705 L classifies it as a Category 3 flammable liquid and lists a 108°F flash point and 328 g/L VOC. The current SIP-1133™ SDS describes a water-based emulsion with no odor, a 599°F flash point, and non-dangerous-goods status for DOT transport. That is a substantially simpler documented fire and vapor-control profile, especially for DIY-scale spraying and work over waterways. It does not make SIP-1133™ harmless.
What safety controls still apply?
Read the current SDS and label before use. Wear suitable gloves and eye protection, avoid breathing spray mist, control overspray, and contain spills. Do not let SIP-1133™ enter drains or waterways. Bridge-deck work also needs project-specific traffic, fall, wind, containment, and environmental controls.
What does less than $1 per square yard mean?
At qualifying bulk purchase volume and the stated coverage rate, SIP-1133™ material can cost less than $1 per square yard and can be much less than high-active silane material cost. That is material cost only; labor, surface preparation, equipment, freight, tax, project waste, and any special containment requirements are additional. Ask SoyLei for a current project quote and coverage basis.
What evidence supports SIP-1133™?
Construction Materials Testing prepared and tested concrete specimens through 180 freeze-thaw cycles in Project 261121SOY. A separate Iowa State PCC scaling study compared treated and untreated specimens. The Science section links to the results, limitations, peer-reviewed preservation research, and U.S. Patent No. 12,297,150.
