Yes, you can use Kerdi band over Ditra Heat seams. Kerdi band is a waterproofing membrane made by Schluter Systems, which is designed to be used in conjunction with their other waterproofing products, including the Ditra Heat system.
The Ditra Heat system consists of an uncoupling membrane, a heating cable, and a thermostat. The uncoupling membrane is installed over the subfloor, and the heating cable is installed over the uncoupling membrane. The Ditra Heat system is then covered with tile or another flooring material.
To ensure that the Ditra Heat system is waterproof, it's important to use a waterproofing membrane like Kerdi over the seams between the Ditra Heat panels. The Kerdi band is a good option for this, as it is designed to be used over seams and joints to provide additional waterproofing protection.
To use Kerdi band over Ditra Heat seams, you'll need to follow the instructions provided by Schluter Systems. This will typically involve applying a layer of Kerdi-fix adhesive to the seam, placing the Kerdi band over the adhesive, and then applying another layer of Kerdi-fix adhesive over the top of the Kerdi band to seal it in place. Once the Kerdi band is installed, you can proceed with tiling or other flooring installation over the Ditra Heat system.
