The Warmup DCM-PRO Waterproofing Tape Internal Corner is a dedicated waterproofing accessory for the Warmup DCM-PRO electric underfloor heating system. Designed for sealing internal corners, it helps create a continuous waterproofing layer where the floor meets the wall, making it particularly suitable for bathrooms, wet rooms and other areas requiring additional moisture protection.
The DCM-PRO system can be used as a waterproofing layer when installed with Warmup's waterproofing tape and compatible waterproof adhesive. The internal corner provides a dedicated solution for sealing corners, helping maintain waterproofing continuity around the perimeter of the installation.
Warmup lists the DCM-R-I as the DCM-PRO Internal Corner within its range of system accessories.
The internal corner should be installed using a suitable waterproof adhesive in accordance with the Warmup DCM-PRO installation instructions. Ensure the corner is fully bonded and free from air gaps or creases to maintain the integrity of the waterproofing layer.
