 What is a backer rod?

An EPE close-cell backer rod is a small foam rod that is used to fill joints between tiles or other pieces of building
material. Builders and contractors often use this tool initially 
in grooves or cracks and then they apply 
mortar,
sealant, or chinking around it.

The rod adds stabilityprecision, and also typically save time. More commonly closed-cell backer rods are used
as a way 
to add insulation and waterproofing for decks, patios, and walkways that sit outdoors. These tools can
improve the appearance and durability of many different projects.

 

Good Performance

Rods made with closed-cell foam are denser and firmer, which is better suited for outdoor and heavier-duty settings.
It 
repels moistureprovides a firm finish to the gap, and can be set into place with a spray adhesive. It is commonly
used for smaller joints in the 1/4 to 3/8 inch (6.35 to 9.52 mm) range, and it 
possesses a higher insulative value than
open-cell forms.

Primary Uses

Builders use these sorts of foam rods for a number of different construction projects, but almost always in the context of
filling gaps
 where materials join together. They’re most commonly used in tiling and flooring, but they can also be found 
in decorative wall paneling, window sealing, stonework, and counter tops.

The main idea is to use the foam to fill most of the void in a joint so that caulking or chinking material, a mortar-like sealant,
can be applied to finish filling it and create an airtight and watertight seal. The rods also add accuracy and firmness that can
give a more finished look to the end result.

Biggest Benefits

The Rods allow the building materials to move, bend, and flex based on the environmental factors they are exposed to,
such as humidity, heat, cold, wind, and ultraviolet light exposure.

In most cases chinking materials are flexible sealants that will remain flexible throughout their usable life span. They will
stick to the building materials, but not to the backer rod. For this reason, the foam is also called 
a bond breaker.

There are only a few scenarios in which backer rods are essential, but they’re almost always really helpful. Builders can
often use caulking or chinking material to fill the entire gap, but the “cure” or dry time for large amounts of these products
would be a number of days or weeks, depending on the size of the gap. 
Things are a lot faster with the rod, and the results
are often more dependable, too.
