If you’re looking for waterproof roofing cement you can’t do better than Jetcem Waterproof Rapid Repair Sand & Cement. Jetcem is a ready-to-use compound of sand and cement produced by Everbuild and Sika. It’s both easy to use as well as quick setting since it sets in around 30 minutes. If you need a quick repair job it’s the best tool for the job. On top of all of that, it even sets in the cold and wet. Finally, as the name implies, once it sets it is waterproof.
Jetcem will need to be mixed with clean cold water to form cement and will be workable for five to ten minutes. In order to apply it you will need either a patching trowel or a filling knife.
Jetcem Waterproof is particularly useful for repairs that will be exposed to water, such as swimming pools or ornate stone birdbaths. It can repair holes up to 25mm deep. For holes over 25 mm that will see consistent water exposure, plug the hole with expanding foam or gap filler up until you’re 20 mm away from the edge, then use Jetcem Waterproof on the rest.
