MONO® Large Gap Insulating Foam Sealant

MONO® Large Gap Insulating Foam Sealant is a one-component, moisture cure, polyurethane insulating foam that provides maximum expansion to economically fill larger cavities and voids. It expands to form a permanent, water resistant bond to wood, concrete, metal, glass and brick. It stops air infiltration and has minimal shrinkage. Cured foam can be sanded, painted or stained.              

Features & Benefits:

    • Specially engineered to economically fill large openings & penetrations
    • Maximum expansion formula fills non-linear and hard-to-reach voids
    • Airtight & water-resistant bond to most common construction materials
    • Minimizes drafts & pest infiltration
    • Indoor/Outdoor use

Suggested Uses:

MONO® Large Gap Insulating Foam Sealant is ideal for sealing around pipes, ducts, vents, electrical outlets and cables. It can be used for filling large gaps and cracks in foundations, masonry walls, crawlspaces and more. It provides an insulating seal to wood, concrete, brick, vinyl, steel and aluminum. NOT RECOMMENDED FOR USE IN FILLING ENCLOSED CAVITIES (BETWEEN WALLS OR UNDER TUB SURROUNDS). May cause jambs or sills to buckle. Cured foam must be painted or stained for outdoor applications.

Surface Preparation & Application:

  1. Wear safety glasses with side shields and protective gloves. Use in well-ventilated areas. Extinguish all ignition sources during use and cure. All areas not to be foamed should be covered with masking tape or dropcloths.
  2. Clean and remove grease, dirt and debris from application area.
  3. Apply at temperatures between 0°C to 30°C. When applying at low ambient temperatures, the temperature of the can must be at least 10°C.
  4. Screw trigger nozzle onto valve, being careful not to actuate valve. Shake can for 1 minute before use.
  5. Familiarize yourself with the foam by practicing on newspaper. Gauge expansion by allowing test bead to expand for 60 minutes.
  6. With valve end of can down (i.e., with base of can upright during use), pull trigger slowly to dispense foam. Dispense foam into lower part of cavity first and fill to only 50% to leave room for expansion. DO NOT DISTURB FRESHLY DISPENSED FOAM. Cured foam exposed to sunlight must be coated with paint or stain. Wait 24 hours after applying foam to paint.
  7. If idle for 10 or more minutes between uses, shake can vigorously 30-45 seconds before reusing.
