Prime Flex 900 XLV
Prime Flex 900 XLV is a hydrophilic, water-activated polyurethane in a 2:1 Quick Mix cartridge, MPN 11234, for actively leaking joints and hairline cracks. Water starts the reaction and the resin expands into a closed-cell, watertight foam with up to 600% unconfined expansion. No extra catalyst is needed. It is NSF/ANSI 61 for potable water contact, and confined foam can move with the crack as temperature changes.
Key Features
- Hydrophilic polyurethane is used on actively leaking joints and hairline cracks
- Water starts the reaction; no extra catalyst is needed
- Closed-cell foam is watertight after the water reaction
- Unconfined expansion is up to 600%
- NSF/ANSI 61 for potable water contact
Applications
- Actively leaking joints and hairline cracks in concrete
- Water treatment tanks, dams, and elevator pits
- Below-grade walls that leak at the joint or crack

Frequently Asked Questions
What leaks is Prime Flex 900 XLV used on?
Actively leaking joints and hairline cracks in concrete. Typical work includes water treatment tanks, dams, below-grade walls, and elevator pits. The hydrophilic resin is injected through ports and expands into a closed-cell, watertight foam.
What cartridge is Prime Flex 900 XLV on this page?
A 2:1 Quick Mix cartridge, MPN 11234. It is a single-component grout, so no extra catalyst is added. Inject as supplied, or twin-stream 2 parts resin to 1 or 2 parts water.
What expansion does Prime Flex 900 XLV have?
Up to 600% unconfined. Confined in a crack the foam is denser. Confined tensile strength is 450 psi with 350% elongation, so the foam can move with the crack as temperature changes. Shrinkage is under 2%.
What potable-water approval does Prime Flex 900 XLV have?
NSF/ANSI Standard 61 for contact with potable water. Viscosity is 250 to 350 cP at 73 F so the resin can enter tight cracks.
What reaction times does Prime Flex 900 XLV have?
Initial reaction is 30 seconds at 73 F. Full rise is 1 minute 50 seconds. Cold slows the reaction and raises viscosity. pH below 3 or above 10 may hurt foam properties.
What shelf life does Prime Flex 900 XLV have?
18 months from manufacture in unopened containers stored dry between 40 F and 80 F. Precondition to 40 F to 80 F. It is not necessary to pre-mix before use.
