REDGARD AQUASEAL HI-RISE X3
Redgard Aquaseal Hi-Rise X3 is a unique elastomer that expands approximately 300% of its original volume during the spray application. In place yield is +50 mils per gallon per 9.3 sqm when sprayed through Lock N Load gun. As X3 rises, it bridges substrate imperfections to virtually eliminate blowholes and pinholes when applied to porous surfaces such as vertical poured concrete and concrete masonry units (cmu). X3 is formulated with the “Ultrabond” molecule therefore is self-priming in most instances.
- 100% solids, no solvents and no VOCs.
- Extended tack time to allow deep surface penetration.
- Compliant with FDA/USDA for incidental food contact.
Unlike most spray-applied polyureas, X3 has the unique advantage of adhering to many polymeric subtrates, both new and aged, typically without the use of primers or extensive surface preparation.
In house testing has shown excellent adhesion to certain clean, dry surfaces including:
- Primers past recoat window
- Crumb Rubber surfaces
- Certain roofing membranes
- Shotcrete substrates
- Latex rubber
- SBR rubber
- Aged polyurea
- Most metals
- Spray applied bisect to minimise surface preparation labor.
- To fill and protect a variety of porous surfaces.
- Waterproofing exterior basements and foundations.
- Protective elastomer for sprayed-in-place urethane foam.
- Roof systems (metal, concrete, wood, etc).
- Repair existing containment liners.
- To fill or repair control joints, random cracks, and shallow spalls on concrete surfaces.
- Earthen containment lining used with or without geotextile fabric.
- Wastewater containment as a re-surfacer.
X3 is available in Neutral, Medium Grey, and Sand. X3 is photosensitive and will change color in a matter of minutes from spray application. Note: X3 is an aromatic polyurea; therefore, as with all aromatics color change and superficial oxidation will occur. Aliphatic urethane and other suitable topcoats can be used where long-term color stability and increased longevity in full sun exposure are of critical importance.

It is recommended that oxidised polymeric surfaces be power washed with 2500-3500 psi water
pressure to achieve maximum adhesion of X3. If there is a possibility of surface contamination, scrub with a solution of 1/4 tsp. Dawn detergent plus 1 tbsp. of vinegar per 1 gallon of warm water, followed by a thorough water rinse.

The polyol “B” component must be thoroughly power mixed each day, prior to use. Use a folding blade mixer or equivalent equipment. Install mixer through the extra 2” bung hole provided on all “B” drums. Care must be taken not to cross contaminate the individual components with the mixing equipment.
Thinning is not required. Using any thinner may adversely affect product performance.
Apply X3 only to clean, dry, sound surfaces free of loose particles or foreign matter. A primer may be required, subject to type and/or condition of the substrate.
Consult technical service personnel for specific primer recommendations and substrate preparation procedures. X3 can be sprayed over a broad range of ambient and substrate temperatures. Contact technical service personnel for specific recommendations, pricing, and availability of spray and auxiliary equipment.
To reduce the possibility of blisters and blow holes when applying X3 to cementitious or other porous substrates:
- Do not apply on damp or wet substrates.
- Start spray application after peak heat of the day
when surface is cooling.
- Do not apply on areas in direct sunlight.
- The temperature of the X3 material and hose
temperature should be approximately the same
temperature as the substrate being sprayed.
Adhere to instructions on container label.
It is recommended that X3 be sprayed in multi-directional (north-south/east-west) passes to ensure uniform thickness. To achieve optimum mix and rise, nucleation at the gun needs to be a minimum of 9 cfm and 90 psi. To spray X3 using the nucleating kit with a manufacturer synergy proportioner, the liquid temperature must be a minimum 21oC maximum of 38oC and optimum of 32 oC. Follow the instructions attached to “A” and “B” containers.

REDGARD POLYUREA WATERPROOFING SYSTEM
What is Polyurea?
PDA Definition: “A pure polyurea coating/elastomer is derived from the reaction product of a polyisocyanate component and an amine-terminated resin blend”.
Polyurea has various formulations depending on intended use.
Advantages of Polyurea
Polyurea’s fast reaction time (5-15 seconds) leaves polyurethane and epoxy materials in the proverbial dust. It is an autocatalytic polymer. With the fast reaction time, polyureas do not easily react with humidity and moisture in substrates, so the material can be readily applied over cold or damp substrates, such as steel, concrete, wood or PU foam.
Where moisture or humidity is a concern, polyureas outperform any product on the market today. Polyurethanes can be sensitive to high humidity and moisture in a substrate. As a result, they will react with atmospheric moisture or high humidity to produce carbon dioxide gas and cause foaming and/or pinholing in the surface. In contrast, polyureas are not affected by moisture.
If a substrate is moist or has condensation on it, polyurea will perform much better than polyurethanes.
In waterproofing applications, a low modulus and a high elongation elastomer are required to meet the challenge. Polyurethanes have traditionally been regarded as having higher elongation and a lower modulus than a polyurea with a similar hardness. However, the days of polyurethanes having lower modulus than polyureas are over. Modern advances in the chemistry mean polyureas are formulated to feel as soft and elastic as polyurethane.
Modern structural polyurea systems can offer these companies an alternative production material to eliminate government fines and increase profits.
In applications once thought to require high-solids epoxies, polyureas are winning at every turn. In the rail and barge industry, polyureas are used instead because of their superior elongation and high impact resistance. Epoxies will crack and delaminate when exposed to constant pounding.a low modulus and a high elongation elastomer are required to meet the challenge. Polyurethanes have traditionally been regarded as having higher elongation and a lower modulus than a polyurea with a similar hardness. However, the days of polyurethanes having lower modulus than polyureas are over. Modern advances in the chemistry mean polyureas are formulated to feel as soft and elastic as polyurethane.
When it comes to heat resistance and fire retardance, polyureas have the advantage over comparably formulated polyurethane. Because of its formulation, structural/rigid polyureas have excellent resistance to heat distortion and sagging.
Exposed polyurea is widely used in applications such as concrete or geotextile coatings for secondary containment applications. Polyureas’ fast cure times allow it to be rapidly applied to a prepared substrate with minimal downtime for the facility. This has made polyurea the choice of facility managers for walls around and floors under chemical storage of diluted acids, alkali, salt solution, organic solvents and oils. Polyurea provides a strong barrier to spills from reaching the environment.
