Although solid surface bathtubs and sinks are very durable, they are still prone to damage and cracking. Depending on the cause, cracks usually appear around the drain area, on the edges and rim area. Seldom on the bath and basin bottom. A cracked solid surface bathtub can be a great eyesore and it could ruin the entire look of your bathroom. So let's analyze the various crack types and their respective causes.
Leading crack causes in solid surface bathtubs and basins.
Drain overtightening during the installation process is the #1 reason for cracks around the drain area and is a common installation error. Overtightening cracks have a very typical appearance, as shown in the images below.
Remedy: Use your supplier's repair kit to patch the damage. Most of the drain overtightening cracks can be repaired successfully by a specialist repair person.
It is probably the second most common cause of cracks and mostly affects bathtubs. Below are a few illustrative images. Cracks on rims, edges, and corners are the result of physical impact on the product during unsuccessful attempts to move or relocate the tub.
Remedy: Depending on the extent of the damage, it will most likely require a specialist to repair the damage. Severely damaged rims and/or walls will have to result in a bathtub replacement.
Thermal shock is mechanical stress caused by an accelerated change of temperature of a certain point in the material. Thermal shock inflicted crack is the result of a rapid material cooling or heating. When a solid surface bathtub or sink is heated or cooled at the surface, the surface, therefore, will expand or contract but will be restrained by the center, which cannot deform plastically, and this will cause flaws to propagate as fast hairline fracture lines.
Solid surface bathtubs and basins, just like natural stone, glass, and ceramic articles, can crack due to thermal shock when exposed to environmental factors, such as a combination of extreme heat and extreme cold. The sudden drastic temperature change from pouring scalding water into a cold sink or bathtub could easily cause a crack and is the most common cause for problems. The most common bathtub and washbasin area where the thermal shock cracks form is the area directly under the bath filler or faucet spout.
Remedy: These sorts of cracks will have to be fixed by a specialist repair person who has experience working with solid surface models.
No. There are a number of causes that make certain solid surface basins and washbasins more susceptible to thermal shock risks:
A cracked bathtub made of solid-surface material such as AquateX™ can be repaired to look virtually as good as new by cutting a matching scrap piece into narrow strips and gluing them into a smooth channel that fills the crack. Essentially, the repair process is very similar to dentistry work with fillings.
AquateX™ is a very resilient material that allows for small scratches and chips to be sanded out of your bathtub or washbasin. Cracks, however, is a very different problem, one that we recommend leaving to a certified repair specialist.
