Product: Floric Polytech RM 220 - Repair Mortar & Underlayment - Trowel Grade

Description: Repair Mortar RM-220 is a two component cementitious polymer modified repair mortar and underlayment product that is designed for uses over concrete and wood to patch, repair, smooth and slope, or on wood to pitch, slope, smooth or to simply improve wood rigidity for additional coatings or flooring applications. Repair Mortar RM-220 is formulated with a proprietary blend of powders, aggregate, and SBR copolymers, which liquids are packaged in a concentrate form that can be diluted on site with clean water. RM-220 requires a diluted version of its own RM-220 liquid polymer as a surface primer over a clean profiled prepared substrate, and when mixed, RM-220 liquid polymer may be mixed in a wide range of dilutions depending on required use. The dilution rate is dependant on whether it needs to be flexible or rigid.

Repair Mortar RM-220 produces a tenacious bond to concrete with increased compressive strengths, abrasion resistance, while still maintaining a compatible co-efficient of expansion and contraction to concrete, yet the same liquid polymer (in a concentrate form) still produces the flexibility required for a decking underlayment in metal lath for applications over wood. It may be used interior or exterior in a wide range of climates, is environmentally safe, has zero VOC with virtually no odor, and cleans up with just soap and water when wet.

Typical Uses: Repair Mortar RM-220 was designed primarily as a material to patch, repair, smooth and resurface concrete and wood in preparation for other Floric Polytech materials, whether it is for concrete restoration or aesthetic beautification. RM-220 may be applied from 1/8” to 4” thickness or when bulked with large washed aggregate economically up to 6”inches. With its increased compressive strength, adhesion and abrasion resistance, RM-220 may be left exposed to commercial and industrial type traffic or covered with almost any type of floor covering. The improvements over regular concrete as a patch, repair, overlay and pitch product are dramatic, especially in thin sections where conventional concrete fails. Trowel finishing the surface is only necessary to produce esthetics, the material will maintain physical properties if simply left with a light screed finish or a heavy broom.

Repair Mortar RM-220 may also be installed over stable, structurally sound plywood substrates, when incorporated with metal lath, which is fastened appropriately. In many cases it is used to pitch and slope, increase rigidity, limit substrate flexibility, improve flammability resistance and generally prepare decks and balconies to receive a functional membrane waterproofing system. In these cases it is basically a stabilizing underlayment.

Advantages:

• Simple to mix and easy to use.
• Superior performance characteristics when compared to conventional concrete repair mortars.
• Its durability allows it to function in both commercial and industrial type applications.
• Prevents Concrete Scaling, has excellent freeze-thaw resistance and is unaffected by de-icing salts.
• May be used as an exposed repair, interior and exterior in wide range of climates.
• May be rod finished, heavy rough broomed or smooth toweled with a mist of water.

• May reflect working cracks in substrate.
• Not recommended for applications when ambient and surface temperature is below 45 Fahrenheit during installation.
