Joint filler and crack repair system
Linofog provides the industry with a secure and durable joint filler. Its characteristics are an excellent pressure strenght and elasticity.
Linofog is polyurethane-based and best applied with a cartridge gun. Linofog works all the way down to -50°C; however, it must not come in contact with water, moisture or cold temperatures during application. Linofog is also resistant to chemicals which are detailed in the following list.
A high-quality and professional floor treatment is not always sufficient to obtain the best possible result. In order to avoid cracks in concrete floors it has now become common practice to saw notches in 6 x 6 m or 8 x 8 m squares, depending on pillars etc. After 3-6 months at the earliest, the joints are vacuum-cleaned, primed, filled and then sanded with a sanding machine.
Linofog is also suitable for repairing cracks and small rapairs.

LAYING INSTRUCTIONS
Before filling the joints;
- Make sure that the joints/cracks are free from dust and moisture.
- If a foam strip is used, place this into the joint/cracks. The strip must be 2 mm thicker than the joint/crack width. While using rubber strip see below.
- Apply the Linoprimer with a small brush that fits into the joint/crack. 1 litre should cover approx 200 meter, based on width 4mm and depth of 20 mm.
- Let the Linoprimer dry for approx 3 hours (at +14-18 C°).
Filling the joints/cracks;
- Mix the Base (0,7 kg) with the hardener (0,3 kg) using a drilling machine. Make sure that you empty everything in the can with hardener!
- Mix the base plus hardener for minimum 3 minutes.
- Put the spout on the empty cartridge, fill the mixed Linofog material l into the empty cartridge and put the lid on.
- Place the filled cartridge into the cartridge pistol and cut the top of the spout to a suitable size (similar to the joint width).
- Fill the joints or cracks. 1 kg (0,7+0,3 kg) should cover approx 15-17 meters, based on the width of 4 mm and depth of 20 mm.
- Let it dry for at least 15-24 hours (at +14-18 C°).
- Grind the surface with fine sandpaper to a smooth level.
Protection during application;
Dangerous! Ensure good ventilation. Protect face, eyes and hands. Keep away from children.
