Description

 

Joint & Seam Filler is part of the family of PROSOCO R-GUARD® products developed to prevent the unwanted movement of water and air through building envelopes.

Utilize Joint & Seam Filler to prepare open joints, seams and cracks before installing R-GUARD FastFlash; any R-GUARD Primary Air & Water-Resistive Barrier; or other waterproofing and air barrier components in new or existing wall assemblies. Joint & Seam Filler is a high modulus, gun-grade crack and joint filler, adhesive and detailing compound that combines the best of silicone and polyurethane properties. This single-component, fiber-reinforced, Silyl-Terminated-Poly-Ether (STPE) is easy to gun, spread and tool. Use Joint & Seam Filler to fill openings and create transitions where flexible reinforcement is required to bridge gaps and provide continuous support of fluid-applied flashing membranes, waterproofing or air barrier components. Suitable for all climates,

Joint & Seam Filler bonds directly to damp or dry surfaces and cures under a variety of weather conditions. It dramatically reduces surface preparation time by eliminating the need for reinforcing tapes at sheathing joints, inside and outside corners. Use Joint & Seam Filler as part of a building wide PROSOCO R-GUARD® Air & Water Resistive Barrier system, or to prepare surfaces for conventional waterproofing or air barrier components. Appropriate for vertical or horizontal, above-grade applications to concrete, masonry, natural stone, structural sheathing, architectural metals, painted metals, glass, PVC, FRP, EPDM and most other building materials.

Prepare

Application Instructions: Filling Joints, Seams and Cracks

 

SPECIFIER NOTE: Treat joints ranging from 1/4 inch to 1 inch with backer road before applying Joint & Seam Filler. 

 

SPECIFIER NOTE: Joints larger than 1 inch must be structurally improved or addressed with an appropriate transition membrane.

 

  1. Apply a thick bead of Joint & Seam Filler to all sheathing joints, seams and cracks. On plywood, spot wood knots, deep cracks or surface irregularities.
  2. Using a DRY joint knife, trowel or spatula, tool and spread the product. Spread 1-inch beyond seam at each side to 20 to 30 mil thickness.
  3. Allow to skin before installing other waterproofing or air barrier components.

 

Application Instructions: Waterproofing Fastener Penetrations

  1. Spot fastener penetrations with Joint & Seam Filler. On plywood, spot wood knots, deep cracks or surface irregularities.
  2. Allow to skin before installing other waterproofing or air barrier components.

 

Application Instructions: Detailing Rough Openings

  1. Prime all raw gypsum board edges with R-GUARD GypPrime.
  2. Apply a thick bead of Joint & Seam Filler to all inside corners, cracks, joints and seams within the rough opening.
  3. Using a DRY joint knife, trowel or spatula, tool and spread the product. Spread 1-inch beyond seam on each side to 20 to 30 mil thickness.
  4. Allow to skin before installing R-GUARD FastFlash®.

 

Transition

Application Instructions: Flashing Transitions

  1. Fasten the flashing leg to the vertical wall surface using a bead of Joint & Seam Filler or conventional methods. 
  2. Fill any voids between the flashing leg and the vertical wall with Joint & Seam Filler.
  3. Apply and tool Joint & Seam Filler as needed to direct water from the vertical wall to the face of the flashing.
  4. Apply and tool Joint & Seam Filler at inside corners to ensure positive drainage.
  5. Allow treated surfaces to skin before installing R-GUARD FastFlash®.
  6. Use Joint & Seam Filler to fill any remaining surface imperfections to provide positive drainage and continuous support of fluid-applied flashing membranes, waterproofing or air-barrier components.
  7.  

Curing and Drying

At 70 degrees Fahrenheit (21 degrees Celsius) and 50 percent relative humidity, R-GUARD Joint & Seam Filler skins within 30 minutes and dries in 4 hours. Surfaces treated with R-GUARD Joint & Seam Filler are paintable with most paints after 2 hours. 

 

SPECIFIER NOTE: R-GUARD Joint & Seam Filler is moisture curing. Low temperatures and low relative humidity slow dry time. High temperatures and high humidity accelerate drying. 

 

Coverage

Coverage varies based on surface texture and irregularities. Spread 1 inch beyond joint at 20 to 30 mils. Joint width varies 0.0 to 0.25 inch

  • 38.5 to 60.5 lineal feet per 20-oz sausage at 20 to 30 mils
