Install flooring directly to the GenieMat® RST or to the additional layering over the GenieMat® RST if applicable.Fill in gaps with acoustical sealant before taping. Butt the seams together, avoid overlapping.Roll out the material and cut to fit, leaving up to a 1/4" gap on the perimeter.INSTALLATION FOR FLOATING FINISHED FLOOR INSTALLįollow these steps if installing a floating hardwood or laminate, nailed down hardwood, or carpet over the GenieMat® RST. If the smell lingers or the user is sensitive to the smell of rubber, cover the rubber with a 4-mil plastic sheeting. This smell typically fades away similarly to a newly painted room. The rubber can have an odor to it when it first arrives. The GenieMat® RST can be cut with a standard razor knife.

If the joists below can be stiffened using stepped blocking, then layering can be avoided. Read our article Maximizing Rubber Underlayment Performance for more detailed information. The highest rated floor/ceiling assemblies will have resilience in both the floor and the ceiling. Decoupling the ceiling below with GenieClips or resilient channel increases the value of the GenieMat® RST in both concrete and wood structures. Including Green Glue Compound will add to the isolation of both impact footfall and airborne noise. Layering also provides an opportunity to add more damping to the floor with a product like our Green Glue Compound. Layering several pounds per square foot of material over the GenieMat® RST is not required, but recommended in order to maximize the performance of the rubber underlayment in a wood structure. plywood, OSB, MDF, drywall, 3/4" lightweight concrete, or a cementitious board like HardiBacker.

Any heavy material will work for layering, e.g. Layering directly to the sub-floor will help more with low frequency airborne and footfall impact noise transfer while layering over the GenieMat® RST will increase the STC rating by at least a couple points with a slight reduction in low frequency performance. The other way is by layering approximately 7 pounds per square foot of material over the sub-floor or over the GenieMat® RST. The best way is to fix the structural deflection between the joists (read Fixing Structural Deflection). There are two great ways to mimic the performance of rubber over concrete in a wood structure. Rubber underlayment will not perform over wood sub-floors as predictably as it will over concrete. Because of the extreme mass and rigidity of the concrete, the rubber is able to compress properly allowing the rubber to add significant resilience to an otherwise rigid structure.

Rubber underlayment will always perform best over or under concrete, either full pour or lightweight.

The GenieMat® RST rubber underlayment has also been tested to meet ANSI standard 118.12 as a crack isolation membrane as well as IAQ test ASTM D5116 for zero VOC. GenieMat® RST rubber underlayment has been tested to perform under most common floor finishes including, but not limited to, tile, stone, wood, laminate, vinyl, VCT, and carpet with installation directly to wood, concrete, and steel sub-floors. The thicker GenieMat® RST rubber underlayment versions are also recommended when a higher level of performance in isolating impact footfall and airborne noise is required. When the ceiling below is fixed to the framing, then the thicker GenieMat® RST10 or GenieMat® RST12 12mm rubber underlayment are recommended. The thinner GenieMat® RST02 2mm rubber underlayment and GenieMat® RST05 5mm rubber underlayment are recommended when the ceiling below has resilient clips or resilient channel installed. GenieMat® RST rubber underlayment meets both of these requirements in each available thickness.
