Watco Back Up Rod
- Lightwork of heavy-duty repairs
- Structural strength solutions
Watco Back Up Rod is a joint packer for deep floor expansion joints. Push it into the prepared gap before applying the joint sealant to reduce the volume of sealant required and help establish the intended filling depth.
The rod is easy to cut and fit along a joint. It complements Watco Floor Joint Sealant and can also be used as packing where specified for Watco Flexible Joint Repair.
Surface Preparation
Clean the joint and remove loose material and contamination in accordance with the repair product’s instructions. Check the width and the required sealant depth before positioning the backing rod. Repair damaged concrete edges where the chosen joint system requires it.
Technical Data
- Supplied length is 10m.
- Nominal rod diameter is 15mm.
- Used as packing in deep expansion joints before sealing.
- The supplied colour may be white or grey, depending on availability.
Directions for Use
Cut the required length and push the rod into the joint to leave the depth specified for the sealant or repair mortar. Check that the backing follows the joint consistently, then apply the chosen joint product according to its instructions.
The required depth depends on the joint width and the product being applied. Use the supporting application guidance below when planning the joint profile and quantity of sealant.
Limitations
Select backing suitable for the joint dimensions and follow the depth guidance for the accompanying sealant. The rod is a packing accessory and the finished joint requires the specified sealing or repair material.
