To smooth concrete slabs, precast planks, or steel deck use Dura-Cap®.  It's formulated to cap rough, pitted, cracked and out-of-level concrete. In renovation projects, it can be poured directly over old tile and adhesive residue. Dura-Cap can also be used over vinyl asbestos tile. Consult your Maxxon dealer for more details on this safe and extremely cost-effective method of abatement.

AccuQuiet® D18 is designed to meet the changing needs of sound control in multifamily construction.


Crack Prevention Mat Underlayments

NAC-Products-Green-Anti-Fracture-Membrane-CADdrawing.png

ECB® Green consists of a base layer of polymer modified elastomers, permanently laminated to a recycled plastic "stress flex" fiber sheet. Together they form a single 40 mil (aprox. 1/16") high strength, self-bonding membrane that is easily applied. The elastomeric base layer functions as a buffer, absorbing the thermal and structural movement of the sub-floor, while its recycled "stress flex" fiber sheet creates a new flooring surface which will accommodate most mortars, organic adhesives and epoxy setting materials meeting ANSI A118.4.

AccuLevel® G40 is a premium polymer-modified self-leveling underlayment. It delivers a smooth, dense surface that is suitable for an immense array of floor covering options. Special formulation technology reduces the porosity of the surface of the cast underlayment to prevent it from rapidly absorbing moisture from adhesives, thereby eliminating the need of surface sealers in most cases.

AccuLevel® H40 underlayment can also be poured over wood subfloors (reinforcing mesh is required to pour over damaged, weak or voids in wood subfloors. Please consult your licensed AccuCrete® Applicator for details). When required by your schedule this high strength underlayment can be poured prior to drywall installation (for more information on pouring before drywall consult your licensed AccuCrete® Applicator).
