PRODUCT INFORMATION & RESOURCES

DESCRIPTION:

CEMIX LAITITE is a fine, plastic, air setting refractory mortar, designed to harden with heat. It is used in the construction of flues, kilns and ovens, where temperatures can reach up to 1400ºC.

TYPICAL USES:

Used for applications including: 

– Flues

– Ovens & Kilns

ADVANTAGES:

– Ready to use

– Can withstand temperatures of up to 1400ºC

YIELD:

100 bricks will need approximately 20 – 25kg of mortar.

PREPARATION:

The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent the adhesive bonding.

All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement that may cause cracking.

APPLICATION:

1. Stir  before use.

2. Apply the product straight from the pail to the laid face and side of clean, dry firebricks, using a trowel.

3. Press the bricks together and trowel off any excess.

Note: For joints thicker than 3mm or for a crack repair, a suitable refractory sand or aggregate can be added.

DRYING & CURING:

It is recommended to force dry CEMIX LAITITE shortly after the completion of the work. Use a slow fire, gradually increasing the temperature up to a minimum of 300º C. 

Note: CEMIX LAITITE cures as a result of moisture evapouration. Therefore the cure time will be significantly impaired during cold conditions. During extended cure times, extra care must be taken to ensure the mortar does not suffer from water damage. It will not cure at temperatures below 5º C.

CLEANING:

Clean tools with water immediately after use.

STORAGE & SHELF LIFE:

Up to 6 months when stored in the original, unopened packaging, in a dry place at 2C and 50% relative humidity.
