Heat-crazing of a die surface, especially when subjected to repeated heating by molten alloys at high casting temperatures. The resulting fine cracks produce corresponding raised veins on die castings.
A crack or split along the grain in wood plank siding as a result of cupping.
Crackling effect similar to alligatoring where the finish breaks into small squarish patterns. Checking can be caused by improperly dried veneer or finish.
The presence of hairline cracks in a varnish coating, a lacquer coating, a film or in an adhesive coating.
Cracks that appear with age in many large timber members. The cracks run parallel to the grain of the wood. At first superficial, but in time may penetrate entirely through the member and compromise its integrity.
Splits or cracks that normally appear in lumber due to drying or lowering of the moisture content.
A lumber defect referring to the separation of wood fiber across the annual growth rings. Splitting of the wood in logs or lumber, often the result of drying.
Hairline cracks that show up in a finish caused by applying too heavy a coat or too many coats. Also known as spider webbing.
Slight breaks in the surface of the paint film. The breaks are called checks if the underlying paint films are visible.
Splits or cracks in wood caused by expansion and contraction due to humidity changes
Fine cracks on the surface of a die which produce corresponding raised veins on die castings. Caused by repeated heating of the die surface by injected molten alloys.
Development of shallow cracks at closely spaced but irregular intervals in the plaster surface. (Also known as alligator cracking or craze cracks.)
Fine hairline cracks in a dried coating film which begin at the surface and progress downward.
Cracks in wood, naturally present due to the drying process.
the short, shallow cracks on the surface of a rubber product resulting from damaging action of environmental conditions.
Cracking in an intense or advanced stage of wood finish whereby the breaks are so deep they expose the underlying surface.
Fissures that appear with age in many exterior paint coatings. At first superficial, but in time may penetrate entirely through the coating. It produces a pattern of surface cracks running in irregular lines. When found in the top pour of an asphalt built-up roof, checking is the preliminary stage of alligatoring.
Checking is the appearance of wide splits with round edges that occur in the top coat. The cause is usually due to the surface not being clean (could be old paint) or too high a film build or the materials not being mixed properly. The remedy is to remove the old paint, cleaning the surface and mixing the paint ingredients properly.
A defect resulting from excessive decurling.
The appearance of wide cracks or splits in wood caused by expansion and contraction due to humidity changes.
Patterns of short, narrow breaks in the top layer of paint. Checking occurs when the paint loses its elasticity.
Small cracks on the surface of rubber, usually from environmental damage.
a pattern of short, shallow cracks on the rubber surface due to environmental attack; see ozone checking
Slight breaks in the film that do not penetrate to the substrate surface. If the substrate surface is exposed it is called cracking.
Cracks or chinks within the wood material.
The development of slight breaks in a coating that do not penetrate to the underlying surface.
Cracks in the surface of a paint film.
Similar to alligatoring, except that the finish is broken into smaller segments. Crowfoot checking is the name given to the defect when the breaks in the film form a definite three–prong pattern with the breaks running outward from a central point of intersection.When the checks are generally arranged in parallel lines, the defect is known as line checking.Irregular checks without a definite pattern are known as irregular checking.
Small, irregular cracks going partly or completely through a paint film.
The formation of short narrow cracks in the surface of the paint film.
Used to describe cracking found in lacquer finished guitars. Vintage guitars often have checking in their lacquer finishes. Checking is caused by the guitar's wood expanding and contracting with changes in temperature and humidity. Is important to maintain constant humidity and reasonable range of temperature to prevent checking.
The formation of slight breaks or cracks in the surface of a sealant.
Raising or separation of the wood grain of a bat, frequently caused by repeated contact with a baseball on the hitting surface.
A kind of paint failure in which many small cracks appear in the surface of the paint.
Natural development of cracks or splits in wood caused by expansion and contraction due to humidity fluctuations upon varying wood densities.
Small fissures or cracks that appear over time in many exterior paint surfaces. These fissures may eventually penetrate right through to the actual material causing damage to the underlying material.
Paint surface defect that consists of a square pattern of small cracks.
