Designed for all kinds of facings in wet, damp and dry places – in bathrooms, kitchens, baths, laundries, corridors and on stairs.
Recommended for caulking the joint of the tiled surface with the room equipment – around shower cabins, shower basins, joints around bathroom furniture and fittings, wash basins, toilets, bath tubs, kitchen worktops and around sinks.
Recommended for terraces, balconies and façades – permanently and effectively seals joints exposed to atmospheric factors.
For sealing tiles in the corners of the facings and for filling the expansion joints.
Types of joined elements – ceramic, gres-porcelain and clinker tiles, sanitary ceramics, impregnated wood, glass, china, anodized aluminium, stainless steel, enameled surfaces, etc.

MYCO PROTECT – system protecting the joint against fungi, mould and algae, which helps retaining the aesthetic appearance of the facing and healthy climate in the room.
Permanently flexible – retains high flexibility during the whole operation period, hardens without contraction; enables sealing tiles on stable wood-based panels and plasterboards, as well as on floor and wall heating systems.
Ensures aesthetic appearance and durable colour of the joints – it is resistant to UV rays, ageing processes and the influence of cleaning agents.
Forms ideally smooth surface.
Highly resistant to temperatures from -50°C up to +180°C.
Element of the tiling finishing system –  in combination with corresponding in colour AVAL and ATLAS grouts and finishing strips.
32 colours – matching the colours of AVAL and ATLAS grouts, silicones and trims, including transparent silicone.

Substrate preparation
The substrate should be dry, clean and free from dust, dirt and other contaminations adversely affecting the adhesiveness. Surfaces adjacent to places to be filled with the silicone should be protected with protective tape.
Before application, remove the nozzle and cut the tip of the cartridge. Then install the nozzle and cut it at angle to the width corresponding with the width of the joint. Insert the cartridge into the caulking gun. Press the silicone out in a uniform way and with little excess into the joint, continuously, without gaps or empty spots. Shape the surface of the silicone within 5 minutes of application and finally smooth it with a putty knife or another appropriate tool soaked with water with a small addition of soap or dish washing liquid. It is recommended to shape the joints in a way enabling free water dribbling. After smoothing the joints, remove the tape protecting the surface of the caulked elements immediately.
Usage of the floor
Slight pedestrian traffic is possible already after 3 hours from caulking. The sealed surface is ready for full functional load after ca. 24 hours.

The consumption depends on the width and depth of joints. Example consumption for the most common applications is presented in the table below illustrating the number of running meters of the joint obtained from one cartridge.

• The sanitary silicone must not be used for mending fish tanks, mirrors and other surfaces where the silicone can have contact with food or drinking water.
• In order to avoid various shades of colour, it is recommended to use silicone of the same manufacturing date and the same batch number for each individual surface.
• Silicones and grouts are manufactured based on different types of binders, and therefore differ in the degree of smoothness and gloss. These factors naturally influence the colour shade for each type of product.
• In order to prevent the silicone from sticking to the bottom of the joint and ensure the optimum filling only between its side walls, it is recommended to use polyurethane foam backer rod.
• All silicone stains must be removed immediately with petroleum spirits. After hardening they can be removed mechanically only.
• Keep out of reach of children. Keep container tightly closed. Avoid contact with eyes. In case of any alarming symptoms call a doctor or transport the victim to hospital, show preparation package, label or safety data sheet. Follow the instructions in the Safety Data Sheet.

The silicone has to be transported and stored in tightly sealed original packaging, in dry conditions and temperature between +5°C and +25°C. Shelf life in conditions as specified is 18 months from the production date shown on the packaging.
