Preventing Common Caulking Failures with Backer Rods
December 16, 2024
Preserving a building’s structural integrity requires sound technical knowledge. Engineers, architects, and contractors frequently inspect buildings for unchecked cracks. Even seemingly small cracks pose a threat to the building’s structural integrity. They should be dealt with as soon as possible before further deterioration. Caulking is the go-to method to effectively seal cracks. However, it needs to be done right to prevent recurring damages. Crack sealing becomes easier and more efficient with backer rods. These flexible polyethylene foam rods strengthen the seal and prevent moisture and water infiltration. Read this blog until the end to learn how to prevent caulking failures with backer rods.
Incorrect Joint Designs Lead To Caulking Failure
Accommodating Joint Movement
One of the problems with incorrect joint designs is the lack of space for caulking expansion and contraction. Such movements lead to cracks in caulking owing to structural shifts. Backer rods accommodate joint movement, preventing caulk from cracking during expansion or contraction. Polyethylene foam used to manufacture these rods is flexible, making it apt to prevent caulking failures.
Poor Adhesion
Improper adhesion is one of the major causes of caulking failures. Three-sided adhesion compromises seal quality. Two-sided adhesion enables sealants to expand and contract without cracking under pressure. Backer rods are sacrosanct for improving adhesion quality by creating the right depth. These flexible rods also reduce the amount of sealant required to fill cracks, leading to reduced costs.
Simplifies The Entire Process
Polyethylene foam has excellent shape retention abilities. It can be squeezed into tight spaces without compromising structural integrity. The shape retention of backer rods helps fill every inch of the crack, simplifying the caulking process. Backer rods ensure uniform caulking, reducing the risk of failures.
