Type

Powder based on fast-setting cements and special fillers

Maximum joint width: 07 mm

When mixed with water, a smooth, paste-like mortar is formed that is easy to process. The mortar remains washout resistant even in wide joints and at low temperatures, does not burn, has high adhesive strength, and bonds firmly and crack-free in the joints. The joints are load-bearing and durable.

Processing

In a clean mixing container, add clear water and mix the powder into a lump-free mortar. Mixing ratio: 250 kg ARDEX GK with approximately 4 l water. The mortar is workable for about 30 minutes at temperatures between 5°C and 20°C. Higher temperatures shorten the processing time. The mortar can be easily applied into the joints with a rubber trowel or jointing board. Deeper joints can also be filled in one step without sticking. The short setting time allows for timely washing without washing out the joints.

Process ARDEX GK at temperatures above 5°C.

Important Notes

• Porous surfaces or matte glazes of tiles and slabs may cause residuals of the joint material to settle. No testing of such surfaces can be omitted.
• When cleaning off excess, the joints must be wetted beforehand.
• Moisture of the substrate and varying absorption of tile edges can cause color differences in the joints. Conduct trial joints in uncertain cases.
• When using aggressive cleaning agents, observe manufacturer instructions. Overdosing should be avoided.

General Information

Instead of cement-based joint materials, epoxy resin joint mortar ARDEX WA should be used in health and thermal insulation buildings and other highly stressed structures.

For joints of moisture-sensitive natural stone slabs indoors, use ARDEX MG Marble Joint.
