The foam satisfies the fire resistance requirement of 240 minutes at a depth of 20 cm and is suited for quick and inexpensive sealing between concrete elements, Leca and similar where the top finish is not required. To install the rod, you can use your fingers or a smooth rounded ended tool to push it into the gap, leaving the finished surface approximately 5-mm back from the front edge of the face of the gap, to allow the silicone to adhere to both the rod and the two edges of the structure it has been injected into.

Using this foam filler rod means that less silicon sealant is needed as it stops it from extruding deep into the gap. Due to covid and new contactless deliveries, our carriers will not require a signature but will take down the recipients name as POD. It is important to avoid over-compressing the backer rod, as this can cause it to lose its shape and affect the performance of the sealant. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. When installing backer rod, it is important to carefully measure and cut the rod to the correct length for the joint.The 103 third parties who use cookies on this service do so for their purposes of displaying and measuring personalized ads, generating audience insights, and developing and improving products. All I did was cut to size, apply sealant to both faces and press into place, then remove the excess silicone. Backer rod is a flexible foam material used in construction projects to fill gaps and voids between two building materials.

They mention that it's a great product, works great in between floorboards, and is suitable for gaps 6 to 8mm high. There are many benefits of using a backer rod, including improved sealant performance, improved aesthetics, increased durability, reduced maintenance, and saving time and money. Bond-It De-Bond Mate is A non-drip gel formula for the complete removal of cured silicone sealant, particularly when silicone has been accidentally smeared over glass, ceramics or countertops.Everbuild Firefoam B2 Handheld is a quick setting one part polyurethane foam with fire resistance properties. This makes for a total seal and the foam would flex during temperature changes due to weather conditions. Promotes an hour glass shape, this maximizes the bond area but keeps the depth of sealant consistent in the middle allowing for movement. Once cured, the foam can be sawn or plastered over after only an hour providing the working temperatures (can and surfaces) are between +5oC to +25oC, ideally 20oC. It can also be incorporated into side insulation and expansion joints preventing heat loss and provide acoustic properties.

I’m particularly bad with sealant I never get it applied in a smooth manner without creating an awful and sticky mess.Fantastic Company with just about possible colour Sealant you could ever want and a really wide range of products available.
