Accessible
No special equipment, containers, or expanding tools are needed to apply KF Road Maintenance N. Simply mix the two bags of material for about 30 seconds and spread it with a trowel. Anyone can easily apply the product.
Quick
KF Road Maintenance N can be open to traffic in 40 minutes after application, regardless of the season. KF Road Maintenance N can also be applied on wet road surfaces, eliminating the need to dry the road surface.
Clean
From zero rubbing to 100 mm thickness, KF Road Maintenance N can be used for a wide range of bumps. It is also extremely smooth to work with, allowing even first-time users to repair smooth and beautiful bumps. The trowel can be simply rinsed off with water after application, and the product has little odor, making it easy to clean up and care for the surrounding environment.
Construction Method
Foundation preparation
Clean the substrate and mask the surface to be applied with masking tape. It is not acceptable if the surface is slightly wet, although puddles are not acceptable.
Mixture
Put the resin solution into the aggregate bag, and rub the whole bag to mix it so that there are no lumps.
Paving
Pour the mixed material onto the surface to be applied and spread it out with a metal trowel to make it smooth. A large metal trowel is recommended to prevent unevenness and ensure a clean application.
Construction Method
KF Road Maintenance N has excellent physical properties and can be used for medium- to long-term repairs and step correction.
