Product Overview


The AQUALAB PUR is a two-component low odor water-based aliphatic polyurethane floor coating system which has low VOC. The product is offered in a smooth (no orange peel) gloss, satin and a matte clear finish and is non-yellowing. The gloss is also available in a colored version. It can be applied directly on the concrete or as a protective and decorative layer over Labsurface’s LABPOX epoxies. The AQUALAB PUR has a superior chemical resistance which makes it an ideal candidate to protect standard epoxies from staining prematurely. It also offers an additional UV protection that will significantly slow the yellowing of the epoxies. The AQUALAB PUR formulation is based on advanced aliphatic water-based polyol technology displaying superior aesthetic finish and excellent UV stability.

SURFACE PREPARATION: Concrete should be clean, dry and free of grease, oil, paint, curing agents or any contaminants that may inhibit proper adhesion. Concrete should be cured at least 28 days before applying the coating system. If the concrete slab has been installed within 28 days, the LABPOX MVB moisture mitigation system can be considered (refer to the LABPOX MVB technical data sheet for additional details). Proper testing procedures should be practiced with regards to soil acidity and moisture vapor transmission. Take a pH reading to ensure concrete is neutral (a reading between 5 and 9 is acceptable). Use a Tramex CME / CMExpert to measure the moisture content of the concrete slab. Moisture content must be below 4% before applying the product. It is necessary to take several measurements at various places on the slab. If the reading is higher than 4%, steps will be required to neutralize the soil moisture. The first thing to do is to make sure that the floor is completely dry before application. Floors with higher results can receive the LABPOX MVB moisture mitigation. Surface must be shot blasted or prepared with an equivalent mechanical means in line with CSP 1-2 depending on the application. Ensure the surface is free of contaminants, and the pores are open to allow the product to penetrate. The product can be applied over Labsurface’s LABPOX epoxies as well as LABFAST and LABSHIELD products without a mechanical bounding if the products have been applied in less than 24 hours. If the product is applied over an epoxy from another manufacturer, it is imperative to do proper tests prior applying the AQUALAB PUR. When applied over an epoxy, a mechanical preparation of the epoxy will improve the adhesion of the AQUALAB PUR. The epoxy coating should be sanded with a proper floor machine. Vacuuming and wiping properly prepared surface will ensure no loose dust particles from the sanding process are present.

MIXING: Before final mixing, pre-mix part A individually at low speed. Then, mix five parts of A and one part of B together at low speed in a separate container. The mixing container must be clean and free of any outside particle. Mix thoroughly for a minimum of three minutes, until a completely homogeneous mixture is obtained. Use a low speed drill (300-450 rpm) to minimize air entrapment. It is recommended to activate the mixer in the reverse mode after the first 90 seconds for the liquid to mix from the bottom of the mixing can to the top. Make sure to scrap sides and bottom of mixing container so no unmixed material remains. Mix only the necessary quantity to be used according to the specified pot life / working time. Adding up to 10% of water to A+B can improve ease of application.

APPLICATION: Apply only when air and floor temperatures are between 15°C / 59°F - 30°C / 86°F, and with a relative humidity of less than 80%. If a heated floor is installed, ensure that the system is turned off during application and for the full duration of the cure. Adding up to 10% of water to A+B can improve ease of application. Any significant variation in thickness may differ results. Two coats are recommended to assure a uniform finish. For applications directly on concrete, test sections should be completed prior to installation as adjustments may be required depending on the porosity of the substrate and field conditions. Dip and roll method is recommended using a 5 mm low nap lint-free roller. It is recommended to apply the product in only one direction (either north-south or east-west). Doing so will ensure uniformity in all planes. Apply evenly without applying pressure to the roller. Avoid creating extra thicknesses or ridges as these will take longer to cure and may remain white after curing. Keep a wet rim during application to minimize the appearance of possible overlap lines. Allow the first coat to harden completely before proceeding with the second coat. For the gloss and satin versions, it is recommended to apply the product between 5 and 6 mils per coat (wet) to obtain a smooth finish with no orange peel. For the matte version, it is recommended to apply between 2 and 3 mils per coat (wet).

RECOAT: A second coat of AQUALAB PUR can be installed 4-6 hours (at 22°C / 72°F) after the first coat. It is recommended to gently sand (approx. 180 grits) the product prior to applying the next coat. Do not recoat without sanding if the last coat of the product was applied over 16 hours ago (at 22°C / 72°F). Beyond 16 hours, the floor surface should be sanded/abraded and vacuumed. Prior to applying the following coat, it is recommended to use a clean cloth and water to remove all the dust from having vacuumed. The product can be applied over Labsurface’s LABPOX epoxies as well as LABFAST and LABSHIELD products without a mechanical bounding if the products have been applied in less than 24 hours.

CLEANING: Due to their chemical nature, matte finishes require a more thorough cleaning process than the gloss or satin finishes. For many users and installers, the matte finish remains an ideal choice for light traffic residential or commercial applications. The gloss and satin finishes are easily cleanable, providing optimal results for all applications including heavy traffic industrial applications. LIMITATIONS: Requires a dry substrate. Moisture content of the substrate must be measured with a Tramex CME / CMExpert at must be below 4% before applying the product. This product should not be applied to concrete substrates that show high levels of moisture/ humidity unless a moisture a LABPOX MVB moisture mitigation system is used. The LABTEC Universal Pigment Pods are not compatible with the AQUALAB PUR. This product will take more time to cure in a high humidity environment. Although this product may be applied in a certain range of thickness, limitations may apply when taking into consideration curing time. Everything else being equal, thicker is the film, longer is the curing time. Do not exceed suggested thickness levels since the product may cure with a cloudy finish. Temperature will also impact curing time. Curing time may extend significantly at lower temperature levels. It is not recommended to install the product on a hot surface. Keep the product stored at room temperature to ensure consistent results. It should be noted that the matte or gloss finish of the coating can vary when installed on unsealed concrete and / or with a spreading rate lower than what is recommended. Labsurface stands behind the quality of its products. However, Labsurface cannot guarantee results since Labsurface has no control over surface preparation, operating conditions and application procedures. Clients are solely responsible to test Labsurface’s products to determine if they perform as expected. To meet our strict requirements, we are continuously testing our coatings and on occasion, formulations may be modified to improve certain properties within each coating.
