RapidXT - One Day Flexible Polymer Coating - Interior or Exterior

RapidXT is a two-component, fast-set, high solids, VOC-compliant, flexible polymer formulation designed primarily as a primer/basecoat across diverse flooring settings. RapidXT offers quick tack-free times while maintaining sufficient workability which enables a 1-day flooring solution. Apply a pigmented polyaspartic for a 1-Day neat system. RapidXT can function solely or alongside various decorative components such as quartz, micas, or vinyl paint chips. RapidXT is also a great choice for exterior flooring applications like patios, or pool decks.  An accelerator option is available for maintaining curing times in colder conditions. Speak to a Spartan Epoxies Expert today to learn more about the capabilities of RapidXT.

Varies by reagent, from temporary splash exposure to long-term immersion based on specific chemicals. 

Application Notes:  

• Primer not required. 

• A topcoat with UV stability (e.g., polyurethane or polyaspartic) recommended. 

• Not UV color stable; environmental factors may affect color stability.

• Intended as a flexible protective membrane, not a finish coat; surface irregularities may occur. 

• Substrate temperature must be at least 5°F above dew point. 

• New concrete must cure for a minimum of 30 days. 

• Product must be mixed thoroughly. 

• Conduct a trial installation off-site to familiarize with product properties. 

Limitations:  

• Color and texture may vary between batches. 

• Ensure environmental conditions are suitable for application to prevent issues related to humidity, chemical exposure, or lighting.
