LABFAST LOW ODOR High Performance 85% Solids Polyaspartic

*****FREE SHIPPING*****

The LABFAST LOW ODOR is an 85% solids, two-component (1A:1B) polyaspartic.  It's a non yellowing floor coating used with vinyl flakes and other floor systems. The LABFAST LOW ODOR is used as a base coat (colored) and a clear topcoat using a common hardener. The system provides a quick turnaround with very rapid curing time with a tack free of approx. 45 minutes allowing the installation in a single day. The product displays excellent curing capability even at very low temperature levels. This product offers superior mechanical and chemical properties and is low maintenance. It also displays a superior aesthetic finish and excellent UV stability which makes it ideal for interior and exterior applications. Two- or three-coat systems can be considered.

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. The LABFAST LOW ODOR does not chemically bound to the LABPOX MVB, flakes or silica sand aggregates are required to get
a mechanical bound (refer to the LABPOX MVB technical data sheet for application 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 calcium chloride test to measure moisture vapor transmission. Readings of 3.5 lbs/1000 sq. ft. during a 24-hour period or less are acceptable for applying coatings. Floors with higher results can receive the LABPOX MVB moisture mitigation system (refer to the LABPOX MVB technical data sheet for application details).

Surface must be shot blasted or prepared with an equivalent mechanical means in line with CSP-2 or more. Ensure the surface is free of contaminants, and the pores are open to allow the product to penetrate.

If the product is applied to an existing LABFAST flooring system that has been cured for more than 24 hours (at 22oC), the floor surface should be sanded properly until a matte appearance is reached above and between the flakes. To achieve this result, it is necessaryto sand in a multidirectional way and on more than one occasion. It is also necessary to use xylene to remove all dust after sanding and to soften the existing layer so that it can merge with the new layer. The use of xylene for this task is mandatory.

If the product is applied over an existing LABPOX flooring system that has been cured for a period longer than 24 hours, it should be sanded with a proper floor machine. A mechanical bound to a sanded surface is required and the pores of the existing coating must be opened for better adhesion. Vacuum dust and properly wipe the surface with alcohol prior applying the LABFAST LOW ODOR. Conduct adhesion tests if there is a doubt about surface preparation. 

The base coat with the flakes should be scraped and cleaned after appropriate hardness is reached prior applying the topcoat.

Mixing: 

Before final mixing, pre-mix part A individually at low speed. Special attention must be paid to colored versions of the product since pigments may have separated from the rest of the formulation during storage. Mixing should be done until the color is uniform. 

Then, mix one part 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 the entrapping of air. It is recommended to activate the mixer in the reverse mode after 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.

Application:

If a heated floor is installed, ensure that the system is turned off during application and for the full duration of the cure. The product has been specially designed to adhere on concrete surfaces.

Once the surface has been properly prepared, squeegee and back roll the product. It is recommended to apply the product in a multidirectional (north-south, east-west) motion to ensure proper coating thickness.

The LABFAST LOW ODOR is used as a base coat (colored) and a clear topcoat using a common hardener. A prolonged working time version (+) and a fast cure version (-) are available. 

When installing a flake system. Do not exceed a thickness of 20-30 mils for the entire system as solvent entrapment may occur above those levels. It is important to match the color of the base coat with the blend of the flakes used. Labsurface has made recommendations to that effect. Most of the blends are better matched with our pre-tint colors but some blends are better matched using our LABTEC Universal Pigment Pods (see LABTEC Vinyl Chips section).

It is also possible to use the LABFAST LOW ODOR as a protective coat over epoxy. In addition to offering a superior chemical resistance and cleanability, the LABFAST LOW ODOR also provides additional UV protection that will significantly slow the yellowing of epoxy. It will also provide a high gloss finish. Colored versions of the LABFAST LOW ODOR can also be used as a protective coat, either pre-tint or using the LABTEC Universal Pigment Pods. When used as a protective layer on epoxy, a thickness of 10 mils is recommended.

Proper tests should be conducted prior application. Contact a Labsurface representative for additional information.

Recoat:

If the product is applied to an existing LABFAST flooring system that has been cured for more than 24 hours (at 22oC), the floor surface should be sanded properly until a matte appearance is reached above and between the flakes. To achieve this result, it is necessary to sand in a multidirectional way and on more than one occasion. It is also necessary to use xylene to remove all dust after the sanding and to soften the existing layer so that it merges with the new layer. The use of xylene for this task is mandatory. Make sure the solvent is completely evaporated and there are no residues. In case there are remaining residues, wipe the surface using a dry rag or swab.
