Crazing Cracks are cracks on the surface in a hexagonal pattern. It occurs due to shrinkage, not enough curing, acidic water used, and weathering actions.
Measures taken to avoid crazing Cracks:
1)Do sufficient curing during construction.
2)Use sand with 75 mm size particles. Remove all particles greater than 75 mm in size by sieving.
3)Proper workability concrete used.

Crazing is a system of fine splits, normally in a hexagonal pattern, which measures somewhere in the range of 5 and 75 mm over every hexagon. They are typically exceptionally fine and shallow and don’t reach out through the whole depth of the plaster. They are generally the consequence of over trowelling a rich blend (one with a high cement content) or utilizing sand containing an inordinate measure of dust (over 15% by mass passing a 0,075 mm sieve). Crazing regularly happens inside a couple of hours of the mortar is applied to the divider and breaks may barely be obvious until residue or dampness makes them observable. Craze cracks are of little significance, don’t open and close with time, and can be covered using any quality paint. On the off chance, glass fiber tissue can be applied during the painting activity.

Crazing crack is a network of fine cracks, usually in a hexagonal pattern, which measure between 5 and 75mm across each hexagon. Crazing often occurs within a few hours of the plaster being applied to the wall and cracks may hardly be visible until dust or moisture makes them noticeable.

Crazing is a network of fine cracks usually in the shape of a hexagonal pattern of varying size from 5 to 75 mm. This defect occurs in plastered wall surface because over troweling of rich mix or sand containing excessive amount of dust.

Basically, it’s a combination of cement and sand
For example- we can use it over a brickwork which will give good appearance and can also be used as a soundproofing agent

Crazing often occur within a few hours of plaster being applied to the wall and cracks may hardly be visible until dust or moisture makes them noticeable. These cracks normally occurs when a plaster mix with a high cement content is used or the plaster is allowed to dry too quickly.
