Everbuild Sikaseal 414 Backer Rod Box of 13mm 489410 - Non absorbent compressible grey closed cell polyethylene foam backup and bond breaker material, Backer rod is insert into a joint to control sealant depth and create a backstop to allow the proper depth of sealant ready for tooling.

Having the correct depth to width of sealant is a very important part of the sealant application process it not only creates a joint the is 2 sided not 3 and the correct width to depth of sealant this allows for the correct amount of movement in the sealant being used whether its around door and window frames to floor and wall expansion joints, this also has the added benefit of saving money on wasted sealant by far the most expensive side of the job.

A 3 sided sealant joints will not have the same movement capabilities as a 2 sided joint they will be hard and have little movement and will fail.

Normal joint requirement 2 wide to 1 deep but check with the silicone or sealant literature.

Everbuild Sikaseal 414 - 13mm Back Rod Applications:

• General Purpose 13mm Sealant backing material.

• Log Homes.
• Draft Proofing & Acoustic Work.
• Can be used in many void fill gap filling applications.
  

Main Points:

• Box of 13mm Round Polyethylene Backer Rod foam joint filler and backing for sealants and acoustic applications.
• Compresses easily for accommodating joints of varying widths.
• Does not stick to sealants the polyethylene backer rod will break away with movement from the back of the joint creating a superior 2 sided joint.
  
• Non-stick closed cell skin.
• Also has good acoustic property's.
  
• High moisture resistance.
• Compatible with all know types of sealants.
• Controls depth of the sealant in proper relation to joint width.
• Provides backing against which the sealant is applied, forcing the sealant to the sides of the joint.
• Prevents 3-sided bonding, ensuring proper function of sealant.

Choosing the correct size:

Select a backer-rod diameter that is approximately 15 to 25% larger than the width of the joint to give a firm base.

Questions and Answers 13mm Backer Rod 489410:

1. What is the purpose of the Everbuild Sikaseal 414 Polyethylene Backer Rod, and how does it improve sealant application?
Specifically designed to act as a backing material for sealant joints. It ensures the correct depth-to-width ratio for sealant application, improving flexibility and durability while reducing the amount of sealant required. By creating a stable and non-adhesive surface for the sealant, the backer rod helps achieve a more uniform and professional finish while preventing three-sided adhesion, which could lead to joint failure.

2. In what types of projects can the Sikaseal 414 - 13mm Backer Rod be used?
The backer rod is highly versatile and can be used in various construction projects, including sealing expansion joints, construction joints, and glazing applications. It is suitable for use with a wide range of sealants, including polyurethane, silicone, and acrylic. The product is ideal for applications in building facades, flooring joints, precast panels, and concrete construction, where precise joint control and a professional finish are essential, the number one use will be to window and door frames.

3. What are the advantages of using Sikaseal 414 - 13mm closed-cell polyethylene backer rod?
The closed-cell polyethylene structure of the foam offers several advantages. It is lightweight, flexible, and easy to handle, allowing for quick and efficient installation. The closed-cell design prevents water absorption, ensuring the joint remains watertight and resistant to environmental factors. Additionally, it provides excellent compressibility, allowing it to conform to irregular joint shapes while maintaining stability during sealant application.

4. How is the Sikaseal 414 - 13mm Backer Rod installed, and what tools are required?
To install first ensure the joint is clean, dry, and free of debris. Cut the backer rod to the required length and press it into the joint using a blunt tool, such as a Backer Rod Podger or other blunt tool to avoid damaging the material. The rod should be positioned at the desired depth to achieve the correct sealant depth-to-width ratio, typically 2:1. check with the silicone or sealant literature. Once in place, apply the sealant over the backer rod, ensuring it adheres only to the joint sides and not the rod itself and tool off.

5. What sizes and lengths are available for the Sikaseal 414 Backer Rod, and how do I select the right size?
The Backer Rod comes in various diameters, from 10mm to 30mm, as listed. To select the correct size, measure the width of the joint and choose a rod diameter slightly larger than the joint width. This ensures a snug fit and prevents the rod from moving during sealant application. For wider joints, larger diameter backer rods are available to accommodate the increased gap. Always ensure the backer rod is compressed into the joint to provide a secure backing for the sealant.
