Uniflex chamotte mortar, 1.5 kg

Chamotte mortar is used for building, repairing, and grouting fireplaces and their tiles, bonding lightweight fireproof boards, mats, and chamotte slabs and elements to ceramic and metal substrates. It can be used for both minor repairs and the construction of a new fireplace, provided that the correct mixing ratio is maintained and the maximum layer thickness of the mortar in individual layers does not exceed 5 mm.

Preparation of the mortar:

Depending on the extent of the repair or construction, we will decide how much chamotte mortar to prepare at once. For the entire package, you need to prepare a solution of water and water glass (total 1 l) in a 1:1 ratio, i.e., 0.5 l of water glass and 0.5 l of water. Pour the contents of the bag (5 kg) into a container and cover it with the prepared solution, mix well, and let it rest for about 3 minutes. Then lightly mix again, and the mortar is ready for use. We recommend preparing only the amount that can be processed within 2 hours. In case of a work interruption, lightly smooth the material in the container and cover it with 1 mm of water. This prevents drying out and allows you to continue working after removal of the water.

Building and repairing fireplaces:

When building new fireplaces, we primarily adhere to the maximum layer thickness of the mortar of 5 mm. Pre-dampen chamotte bricks and elements before actual construction! For grouting and repairing damaged masonry, proceed as follows: Dampen the repair areas with water, fill them with the prepared mortar, and smooth the surface. The repaired fireplace should be allowed to dry according to the size and extent of the repair for 12-24 hours. Then dry it further by mild heating (2-6 hours) until the repaired areas harden completely.

Bonding to metal substrate:

Remove all greasy contaminants and especially rust from the substrate. It is recommended to use a rust remover. Before bonding, it is advisable to coat the substrate with a thinner layer of mortar. Let the layer dry, and then proceed with the bonding. The mortar can also be used to protect and repair internal masonry and furnaces and metal parts exposed to high temperature. The mortar can be used in all places where the temperature does not exceed 1400 °C.

Safety instructions:
When working, use protective gloves, protective clothing, and safety goggles or a face shield. Observe basic hygiene rules! After work, wash your hands and affected skin with water and soap and treat with a suitable repair cream. In case of eye contact, rinse eyes with flowing water, and in case of accidental ingestion, rinse the mouth, drink 0.5 l of water, and seek medical attention. In more serious cases, always seek medical help.
