What causes cracks in quartz countertops, and what are the solutions?

Cabinets are an indispensable piece of furniture in our kitchen, and it is also one of the key points of the kitchen, we all know that the composition of the cabinet is indispensable countertop, and the countertop of the cabinet has a wide variety, there are artificial stone, granite, and stainless steel countertop, as well as marble material, then.

Quartz. What causes cracks in countertops?

1. Cracking at the splicing joints of the countertop: when the installer is splicing, the seams are not aligned, the glue is not evenly coated or added to the glue.

Curing or promoting excessive relief, making the joints brittle, cracking by a slight impact during use;

2. Cracking at the corner: the wall is too tight and there is no shrinkage joint, the height between the two cabinets is uneven or not flattened, and it is impacted by external force or gas.

Temperature change: uneven shrinkage and cracking of the countertop;

3. Cracking around the basin on the table: there is no gap between the basin and the basin hole, the basin hole is not polished and smooth, and it is impacted by external force or the temperature changes.

uneven shrinkage and cracking of the countertop;

4. Cracking around the furnace hole: there is no gap between the gas stove and the furnace hole, the furnace hole is not polished and smooth, and it is affected by external force or temperature change.

uneven shrinkage and cracking of the countertop;

5. Cracking of the backshield: the cabinet is uneven or the backing plate is not flat;

6. Cracking of the back windshield waterside connection table: the glue is not firmly bonded;

7. Cracking of the center of the countertop: high temperature, impact by external force, uneven cabinet or backing board, internal injury of the plate, etc.

The relevant knowledge about quartz countertops is introduced here, and the above is also a detailed introduction to which kinds of stone cracks will cause these stones, you can check what kind of situation your home belongs to, here is a reminder to everyone: the purchase of quartz stone should be considered and matched with the overall home decoration, the style and color of quartz stone should be consistent with the overall style of the interior.

Find a cabinet manufacturer, they have quartz resin glue, seams, glue, polishing.

In addition to the reason that the edge of the sink and stove hole is not treated and smooth, the cracks around the sink and stove are not left enough clearance for the sink, stove and countertop when installed. After choosing a good brand and thick quartz stone, installation is also very important. Install quartz countertops to ensure that the cabinets and base cabinets are kept level.

If a quartz countertop falls on an uneven base cabinet, the chance of cracking increases.

Cracking in the center of the countertop, etc.: high temperature, impact by external force, uneven cabinet or backing board, internal injury to the board, etc.; Therefore, the main factor causing the cracking of the countertop is caused by the lax quality control of the countertop during the processing process. Generally speaking, if the cracking is caused by the plate itself or the processing and transportation problems of the store, you can apply for after-sales service and replace the new countertop within one year.

Quartz stone is resistant to high temperature, but the phenomenon of thermal expansion and cold contraction is there, so pay attention to leave a certain gap when opening the sink and stove, and the opening size is slightly larger than the outer wall of the sink. The corners should be rounded about 25mm. The opening is at least 8 cm wide, and it is easy to crack if it is too narrow.

In the process of daily use, do not knock on the countertop with gravity, do not put the container with high temperature directly on the countertop, you can lay a layer of heat insulation board; Avoid scratching the surface of the countertop with sharp objects, etc. Choose a regular manufacturer of quartz stone, but also consider an installation, if you need to do kitchen countertops need to open holes, it is best not to choose on-site openings, now the use of hand-held cutting machines is easy to cause collapse or small cracks, a short time can not be opened.

When the countertop is installed, there should be a 2-4mm expansion gap between the countertop and the wall, so as to effectively ensure that the countertop does not crack due to thermal expansion and cold contraction. The maximum distance between the table top and the support frame or support plate should not exceed 600 mm to reduce the deformation or even fracture of the table top; Quartz stone with high hardness, high density, scratch resistance, wear resistance does not penetrate the advantages of the market to occupy the market, although the quality of the plate on the market is uneven, but from the cost performance of quartz countertop is still good.

It is because the quality of the quartz countertop is very bad, and its heat resistance is very small, so when it is subjected to high temperatures, the quartz countertop will crack immediately. When putting things on the countertop, be sure to put some thermal insulation pads first.

Because the inside of the house is too dry, these stones are cracked again, which shows that its quality is not good, and maintaining the humidity in the house can prevent it from cracking.

The biggest possibility is that the thermal expansion and contraction will cause cracks, and the best thing to do is not to put the hot pot on the table.

The joints of the quartz countertops are not normal, and the joints are too obvious and incongruous. The solution is: you can use a hand planer to polish, clean the dust on the surface with a special glue for stone, and the glue color should be basically the same as the material to solve the problem.

It is normal for quartz countertops to appear less obvious joints, but quartz can also be seamlessly spliced, which depends on the skills and experience of the countertop processing master. Generally, it can only be done with more than two years of work experience. In terms of composition, artificial stone.

Including resin artificial stone, pure acrylic.

artificial stone and artificial granite, etc.

The common thing is to use resin for adhesion, because resin artificial stone is generally not resistant to high temperature and has poor hardness, but the best artificial stone such as pure acrylic artificial stone has good plasticity and can be arbitrarily shaped, and artificial stone is environmentally friendly and seamless in addition to artificial granite, which is not possessed by quartz stone.

Because quartz stone is a brittle polymer composite material, it also has the characteristics of thermal expansion and cold contraction, and also has certain mechanical properties such as shrinkage stress, impact toughness, and elongation at break. Winter is the high season for quartz stone cracking, and excessive temperature difference is the most common cause of quartz stone cracking. If it's just a crack, there's a kind of marble gum that can be used to repair it.

There is a gap in the quartz countertop, you can touch the connection with your hands, when there is a gap between the height and the height, you can use a hand planer to polish, and then clean up the dust on the surface, and then use a special glue for stone, the color of the glue should be basically the same as the material, so that it is smeared on the joint. The other is to let the glue dry and polish it with a polishing pad, so that there will be no marks.

1. The quartz countertop is flattened everywhere, so that the gap between the two plates at the joint is as small as possible, and the height difference between the board surface is also small. The control of the gap can be adjusted by cutting or grinding; The control of the height difference of the board surface is adjusted by the way of the bottom pad; Aim for as small as possible, nothing else matters.

2. Touch the connection with your hand, and if there is a slight height difference, you can use a hand throwing machine to solve it.

3. Clean up the dust on the board surface, mix the special glue, and apply the glue color to the seam after the color of the glue is basically the same as the color of the plate.

4. After the glue is completely dry, use a polishing piece of more than 3000 to add water to complete it once, and this step can be omitted if the glue traces of the seam are not obvious.

It is not normal to connect the stove **, and people who make cabinets know that it is best to find a countertop manufacturer for repair, or you can find a store that sells cabinets and ask them to deal with it (asking for money).

Quartz stone is darker is more obvious, other colors are better, the seams are visible, only artificial stone seams are very small, do not pay attention to the words can not be seen, generally in the diagonal place to connect, rarely 45 degrees (front and rear water retaining is 45 degrees).

This seam is too obvious, the lower hanging is not well handled, and if the black part is a stove, the joint must not be too close to this place.

Golandi crack resistant quartz stone] for you to answer.

It should be the theme of glue, generally before making the stone to the glue (also called glue), because some manufacturers of the original glue glue color is not right, to other glue to adjust the color of the plate.

Mostly because of the workers, your lower edge of 45 degrees doesn't do very well.

Summary. Quartz stone cabinet countertop cracks when heated, is it a quality problem?

It's not a quality issue. Although the quartz countertop has the characteristics of heat resistance, it is not hot resistant, and the utensils that have just left the fire cannot be placed directly on the countertop. Quartz stone is resistant to high temperature, but the quartz stone countertop is not pure natural, it is processed with resin, and the resin is not resistant to high temperature.

Quartz stone countertop is first crushed with high-quality natural quartz sand, then purified (removal of radioactive substances), and quartz stone crystals (90%-94%), resin (6%) and trace pigments and other materials are pressed together by isomeric polymerization technology under vacuum conditions. Extended information: basic knowledge of quartz countertop maintenance:

1. Do not put the high temperature or hot pot directly or for a long time on the countertop, and the hot pot, kettle or other utensils and utensils that are too high temperature taken directly from the stove or oven or microwave oven will cause damage to the countertop. 2. In the operation, you should try to avoid scratching the countertop with sharp objects, no matter what kind of countertop you choose, you should cut vegetables and cook food on the cutting board, in addition to avoiding leaving knife marks and damaging the blade, you can also achieve better cleaning and hygiene. 3. Keep the countertop dry as much as possible Keep the countertop clean, try not to soak or accumulate water on the countertop for a long time, and keep the countertop dry.
