NA 1200

Shower Base Mix – Cement-Based Trowelable Underlayment

NA 1200 Shower Base Mix is an economical blend of select sand and Portland cement. Mix with water to create a semi-dry underlayment mortar bed from 3/8″ to 3″ (10 mm to 7.5 cm) thick. NA 1200 Shower Base Mix is excellent for leveling rough or uneven concrete floors, and for building slopes on shower floors or other surfaces before installing ceramic tile or stone.


NA 1300

Magna Float™ – Wall and Floor Rendering Mortar

NA 1300 Magna Float is a pre-blended, cement-based, polymer-fortifed 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

Membrane Primer – Roller-Applied Crack-Isolation Membrane Primer

NA 1510 Membrane Primer is a ready-to-use, fast-drying, water-based latex primer for use under NA 1550 Crack-Isolation Membrane on indoor and outdoor floors for residential and commercial applications.
