Seal floor joints

Sealing of floor joints

The sealing of floor joints is a major challenge, especially in public and commercial areas. Expansion and compression movements, mechanical stress from walking or cleaning and other stresses place high demands on the products and are elementary when selecting the sealant. When it comes to elastic jointing, it is also important to select a suitable sealing compound for the floor joints. The greatest innovation in the field of sealants in recent years is the so-called MS Polymer. Modern MS polymer products such as the CF MULTI have, among other things:

  • high elasticity
  • high weather and UV resistance and can
  • be painted over with water-based paint systems and
  • be used both inside and outside.

An MS polymer sealant can be used in a wide variety of areas and not only impresses with its low odor level, but above all with its good compatibility with the treated substrates. Another advantage is that the cleaned substrate is stable, clean, dry and free of dust and grease, the sealant can be applied immediately without priming thanks to the integrated primer. It is advisable to mask off the area around the joint during processing to prevent the sealant from getting onto the surface of materials. After the joint has been smoothed and the specified curing time has been observed, MS polymer sealants can be painted over with water-based paint systems.

The following steps should be carried out for a perfect joint:

Step 1: Clean the joint

Step 2: Mask off the joint edges

Step 3: Prepare cartridge and cartridge press (silicone syringe).

Step 4: Insert the cartridge into the cartridge press

Step 5 draw joint

Step 6: Spray the joint with a water-washing-up liquid solution

Step 7 : Strip and smooth the joint

Step 8 : Wait for the hardening time and paint over the joint if necessary
