Joint Seal

Ramseal FLX-200

Two-component 100% solids zero VOC polyurea — high elongation crack filler

Overview

Ramseal FLX-200 is a two-component, 100% solids, zero VOC, elastomeric polyurea sealing system designed to act as a crack filler for use with small to large cracks in concrete, masonry, and other cementitious substrates. It provides exceptional adhesion characteristics and fast cure times. Highly chemical resistant, insensitive to water, abrasion resistant, and thermally stable from -20°F to 250°F (-29°C to 125°C). It may be used under traditional floor coatings or any Ram Urethanes top-coating materials. Compared with Ramseal FL-100, FLX-200 offers higher elongation (>700%) for greater movement accommodation.

Key Features

Ultra-High Elongation (700% ±50%)

700% ±50% elongation (ASTM D412) — significantly higher than standard polyurea sealants — allows FLX-200 to accommodate large joint movement, thermal cycling, and dynamic crack activity without failure.

Zero VOC / 100% Solids

Fully solids polyurea formulation with zero VOC — safe for use in occupied spaces including food-processing plants, cold storage facilities, and interior warehouse environments.

Fast Return to Service

Gel time of 3–5 minutes and return to service in 20–30 minutes under normal conditions, minimizing downtime in high-traffic industrial and commercial floors.

Broad Thermal & Chemical Resistance

Thermally stable from -20°F to 250°F and highly chemical resistant — suitable for refrigeration floors, food-processing plants, chemical spill-prone environments, and under ceramic tile floors.

Typical Applications

  • Expansion joints and concrete crack filling
  • Heavy traffic warehouse and industrial floors
  • Refrigeration and cold storage floors
  • Airports, bridges, and parking decks
  • Food-processing plants and naval decks
  • Walkways, balconies, and pothole road repair
