NA 240

Primer Grip™ – Multi-Surface Primer for Tile, Stone and Self-Leveling Underlayment Installation

NA 240 Primer Grip is a high-performance, textured, water-based primer designed to enhance the performance and adhesion of mortars to existing ceramics and difficult-to-bond substrates.


NA 310

Self-Leveler Primer – All-Purpose Primer for Self-Leveling Underlayments

A low-VOC, water-based acrylic primer that enhances the performance and adhesion of self-leveling underlayments (SLUs) on nonabsorbent surfaces such as ceramic tile, vinyl composition tile (VCT) and adhesive residue, as well as on profiled, absorbent surfaces. Ideal for a wide variety of substrates, NA 310 dries clear and combines excellent versatility with easy application.


NA 400


A high-compressive-strength, cement-based underlayment and repair mix that is easy to pour and that seeks its own level. It is ideal for leveling, smoothing and repairing interior floors up to 1″ (2,5 cm) in a single application. NA 400 is extremely convenient: Just mix with water and pour over the floor substrate. Its fast cure time allows tile to be installed after just 24 hours.


NA 420

LP Leveler – Low-Preparation, Self-Leveling Underlayment

NA 420 LP Leveler is a low-preparation, self-leveling, calcium-aluminate based underlayment and repair mix for interior concrete and engineer approved floors. Its unique formulation allows for direct application on substrates that are clean, securely bonded and properly primed. NA 420 has high strength and is abrasion-resistant, and is able to accept tile and stone 16 hours after installation and moisture-sensitive floor coverings after 36 hours.

NA 450

LP Leveler Rapid – Low-Preparation, High-Performance, Rapid-Setting, Self-Leveling Underlayment

NA 450 LP Leveler Rapid is a low-preparation, rapid-setting, self-leveling underlayment that typically requires only a clean, securely bonded and properly primed substrate before application. NA 450 is quite fluid once mixed and it can be easily installed from featheredge to 2″ (5 cm) in a single lift. Typically requiring reduced surface preparation, NA 450 provides lower installation costs and fast turnaround on jobsites. NA 450 is able to accept tile and stone after 3 to 4 hours of installation and moisture-sensitive floor coverings after 16 to 24 hours. It has a compressive strength of greater than 4,100 psi (28,3 MPa) after 28 days.

NA 500

Floor Patch – Rapid-Setting Patching Compound with Polymer

A fast-setting, latex-fortified, sanded, cement-based patching compound with high compressive strength. When NA 500 is mixed with water, floor coverings can be installed in just 1 hour after application. When mixed with the latex liquid NA 501 Floor Patch Additive, NA 500 can be used as an embossing leveler or to encapsulate cutback adhesive residue.


NA 501

Floor Patch Additive – Latex Liquid for NA 500 Floor Patch

An acrylic latex additive for use with NA 500 Floor Patch to improve adhesion and flexibility. When NA 500 is mixed with NA 501, the floor patch system can be used as an embossing leveler or to encapsulate cutback adhesive residue. NA 501 also increases the working time of NA 500.


NA 600

Multi Patch™ – Versatile, High-Performance Concrete Patch

A fast-setting, versatile, cementitious material used for the patching of interior/exterior concrete surfaces including concrete floors, residential driveways, sidewalks and concrete pads.


NA 1200

Shower Base MixNA 1200 Shower Base Mix is an economical blend of select sand and Portland cement.

NA 1300

Magna Float™ – Wall and Floor Rendering Mortar

NA 1300 Magna Float is a pre-blended, cement-based, polymer-fortified thick-bed and render mortar that includes a blend of select aggregates. It can be used for horizontal and vertical rendering. Rather than requiring the use of a latex additive, NA 1300 Magna Float only needs to be mixed with water to produce a thick-bed mortar of exceptional strength.

Membrane Systems And Waterproofing

NA 1510

Roller-Applied Crack-Isolation Membrane Primer

A water-based, acrylic membrane primer designed for priming properly prepared substrates before installing peel-and-stick membranes.
Applied by roller or brush, a coat of NA 1510 is ready for NA 1550 after about 15 minutes of drying time.


NA 1550

Crack-Isolation Membrane

A flexible, thin, lightweight, load-bearing, “self-adhered” membrane over which ceramic tile and natural stone can be installed immediately with any polymer-modified cement mortar.


NA 1640

Crack Isolator™ – Liquid-Applied, Crack-Isolation Membrane

A premixed, liquid-applied, quick-drying membrane applied over concrete substrates to keep cracks from migrating up through ceramic tile and stone installations.


NA 1740

Waterproof Coating – Waterproofing and Crack-Isolation Membrane

NA 1740 Waterproof Coating is a premixed, fast-drying, liquid-applied waterproofing and crack-isolation membrane for installation under ceramic tile or stone in residential, commercial and industrial environments. NA 1740 provides a thin, continuous barrier to protect adjacent rooms and floors below from water damage. NA 1740 can be applied with a roller or brush and is ready to receive tile or stone after 45 to 90 minutes of drying time.


NA 1750

Waterproof Coating Fabric – Waterproof Coating Fabric Reinforcing Polyester Fabric

A thin, flexible, lightweight, alkali-resistant, non-woven polyester fabric for optional embedment with NA 1740 waterproofing and crack-isolation membrane under ceramic tile or stone.
