Cracks and gaps in buildings often lead to unwanted problems and risks. What might seem like a harmless little gap can become a menace. It is imperative to deal with such cracks and gaps as and when they arise. Contractors and engineers rely on sealants to deal with gaps. However, there is one component that they rely on to bring the best out of sealants. We are talking about backer rods. These rods are the hidden heroes contractors often rely on for dealing with pesky gaps and cracks on walls and floors. This blog lists three reasons that make backer rods perfect for filling gaps. 

3 Reasons Backer Rods Are Perfect For Fixing Cracks

 

Helps Proper Adhesion

 
Contractors often fill cracks and gaps with backer rods before pouring sealants over them. This is to create a filler or backing that offers consistent depth. Inconsistent depth and width of a crack might lead to improper adhesion of the sealant. By providing a solid backing, these rods ensure water and moisture stay out of the cracks thus preserving the building's structural integrity.
 

Less Sealant Required

 
Apart from guaranteeing better adhesion, backer rods also reduce the amount of sealant required. Since these rods are flexible, they can be easily squeezed into tiny gaps. Once inside, the backing rod retains its shape occupying the crack. This significantly reduces the need for sealant. Less sealant required means more savings for contractors in material costs.
 

Durable

 
Backer rods are made of polyethylene foam. Also known as PE foam, it is a popular polymer with countless benefits. The flexible, cylindrical rods provide excellent support to the sealant while it cures. The polyethylene foam rods absorb the sealant and help retain its shape over time. The backer rod can last longer and withstand various weather conditions without deteriorating.
