Where priming of the surface material is necessary, primer should be applied only to the sides of the joint surfaces and allowed to dry tack-free before the Backer-Rod is placed. As needed, tool to desired shape using a caulking tool or old spoon. Hint: For polyurethanes, wet the tool regularly with water or toluene to enable a smooth surface.

Soapy water is not recommended as some soaps can interfere with joint bonds. Most products need 24 hours minimum cure before applying any type of over-coating. Follow the manufacturers recommended cures. Application Hint: Use masking tape to create clean lines and on surfaces where you do not want sealants.

Sealants are very difficult to remove from unwanted areas. A polyolefin is a polymer produced from a simple olefin also called an alkene with the general formula CnH2n as a monomer. For example, polyethylene is the polyolefin produced by polymerizing the olefin ethylene. Soft Backer Rod for residential construction is also commonly used to seal air gaps around wall or joint cavities, between pre-hung doors and windows and rough openings in wood frame homes.

The low compression deflection and high compression recovery of these products will not bow windows or door jambs and adapts to seasonal joint movement. Specific uses for Soft Backer Rod includes log homes, marriage joints, sealing at attic access openings, casement window joints, some dry wall applications, wall to wall joints, wall to floor joints, and roof to wall joints, and around doors and windows in wood frame structures.

Compatibility: Our our backer rod products are an inert composition and therefore compatible with all known cold applied sealants including butyl, polysulfide, vinyl acetates, PVA, acrylics, polyurethanes, tri-polymers and silicones. They are chemically inert and will resist oil, gasoline and most other solvents. These materials will not stain nor adhere to sealant materials and are non-exuding. More Information can be found in the Technical Data Sheets. The correct gap makes it possible to finish the exposed edges of the expanded polystyrene, which should be wrapped with reinforcing mesh before the EPS is secured to the sheathing with a waterproofing application of base coat.

Then the rest of the finish goes on. Finally, the gap is filled with soft or closed-cell backer rod and a bead of compatible sealant. Novalink Polyether Sealant is an excellent sealant for this applications. Textured Sealants are also available which cure textured to look stucco-like. Log-In Log-Out. Catalogs Directory.

Primers for sealants Removal tools: to cut out old sealants. Follow suggestions for joint-sealant application as directed by the sealant manufacturer. Soft Backer Rod vs. Closed Celled Backer Rod: Soft Cell is generally used in vertical applications, above ground, or where joints are more irregular, and to fill air-gap spaces in general construction.

Closed celled is generally used for ground level applications and high moisture environments. It can be used anywhere the soft-celled is used.

Either can be used with Self-leveling sealants and Vertical Joint Sealants. Both closed and soft cell are Polyethylene based polyolefin foam. Blog Home Blog.

Foam backer rod comes in several variations suited for specific projects. What is a backer rod and what does it do? Reduce caulk consumption by controlling sealant depth— this prevents excessive use of caulking or sealant. Force adhesive into contact with the sides of the joint creating an hour-glass shape for a superior bond. Closed Cell Closed cell foam is distinct in that its cells are totally enclosed by its walls and not interconnecting with other cells.

Common Uses: Contraction and expansion joints of concrete highways Runways Driveways Parking Lots Open Cell Open cell backer rod is unique; it can easily compress and return to its original state due to unrestricted air movement. Common uses: Expansion and contraction joints Window glazing Curtain wall Construction partitions Precast assemblies and copings Parking decks Bridge construction Open cell backer rods may not be ideal for sealants that are susceptible to bubbling of air escaping the backer rod material.

Bi-Cellular FillPro Soft Type is a unique bi-cellular construction that offers high compressibility, but has a closed cell outer skin to resist moisture. Common uses: Irregular joint applications Armacell offers the widest range of backer rod materials available on the market today. Component Foam Archive. Start typing to browse our database.
