Laminate countertops are a popular choice for durability and affordability. However, they may start peeling over time, leaving unsightly and potentially hazardous edges. As a general rule, laminate countertops peel due to heat and moisture damage, age and wear, poor installation, and chemical damage. Based on industry trends and other data points, the following chart is an estimated percentage of the causes of laminate countertop peeling.
| Reason for Countertop Peeling | Percentage |
| Heat damage | 30% |
| Moisture damage | 25% |
| Age and wear | 20% |
| Poor installation | 15% |
| Chemical damage | 10% |
Why are laminate countertops susceptible to these various factors? Laminate countertops are made of a layer of paper or fabric impregnated with resin and then bonded to a substrate, typically particleboard or MDF (medium-density fiberboard). However, despite their durability, laminate countertops can still peel over time due to combining the above factors.
Avoid Placing Hot Objects Directly on the Countertop
Laminate countertops are not heat-resistant, and placing hot pans or dishes directly on the surface can cause the laminate to warp, bubble, or peel. In addition, if exposed to heat damage, the adhesive used to bond the laminate to the substrate breaks down, leading to peeling.
The Effects of Moisture on Laminate Countertops
Another common cause of peeling is moisture damage. For example, if a laminate countertop is frequently exposed to water, such as in a bathroom or near a sink, the laminate may become waterlogged and start to peel. This can also happen if the countertop is not installed correctly, and gaps between the laminate and substrate allow water to seep in.
How Aging Countertops Contribute to Peeling
As laminate countertops age, they become more susceptible to wear and tear, and their adhesive bonding strength can weaken over time. In addition, as the countertop wears, it may develop cracks, chips, or other surface imperfections that allow moisture to penetrate and weaken the bond between the laminate and the substrate. Furthermore, as the countertop ages, it may also be exposed to different environmental factors, such as changes in temperature and humidity, which can cause the laminate to expand and contract, eventually leading to peeling.
Overall, the aging and wear of the laminate countertop can contribute to peeling, especially if it has not been well maintained or exposed to harsh environmental conditions.
Common Causes of Laminate Countertop Peeling: Poor Installation
Poor installation is another common cause of laminate countertop peeling. If the laminate is not properly bonded to the substrate, it can separate over time and peel away. Various factors, including inadequate adhesive, incorrect pressure or temperature during installation, or poor surface preparation, can cause this.
In some cases, the installer may have used the wrong adhesive or applied it unevenly, leading to weak spots where the laminate can begin to peel. Additionally, if the substrate is not flat or smooth, the laminate may not adhere properly and begin to peel away. Therefore, hiring a qualified professional with experience in laminate countertop installation is vital to ensure that the job is done correctly and prevents peeling.
The Most Damaging Chemicals for Laminate Countertops
Chemical damage can cause laminate countertops to peel, as certain chemicals can break down the adhesive bond between laminate and substrate. As a general rule, acids and alkalines, such as vinegar, bleach, and ammonia, are the most damaging to laminate countertops and can weaken the adhesive bond. This breakdown can occur from exposure to these harsh chemicals and some foods and liquids. Some of these chemicals are more damaging than others and can cause immediate damage to the laminate surface.
Chemical damage can not only cause peeling, but it can also affect the appearance of the laminate. For example, the laminate may discolor or fade, and the surface may develop rough spots or stains.
Preventing chemical damage involves avoiding harsh chemicals on the countertop surface. Instead, use mild soap and water or cleaning solutions specifically designed for laminate countertops. Wipe away spills immediately to prevent prolonged exposure.
Geography: A rarely discussed reason laminate countertops peel
The geographic location of a home can also be a contributing factor to laminate countertops peeling. The high humidity and frequent rain in these areas can cause moisture damage over time, causing the laminate to peel away from the substrate. Some regions in the United States with high heat and humidity levels, such as Florida or other coastal areas, can cause laminate countertops to be more prone to peeling.
Additionally, regions with high temperatures can cause laminate countertops to expand and contract, weakening the adhesive bond between the laminate and the substrate. This can result in the laminate peeling away from the countertop over time.
To prevent laminate countertop peeling due to geographic factors, homeowners can take steps to protect their countertops. For example, using a dehumidifier or air conditioning system can help reduce humidity levels in the home, preventing moisture damage.
Also, choosing a laminate with higher heat and moisture resistance can help prevent peeling in areas with high levels of heat and humidity. It’s also essential to ensure the laminate is installed correctly and sealed to avoid gaps or weak spots where moisture can seep in and cause damage.
Laminate countertops are popular and affordable but can peel over time due to various factors. Heat damage and moisture damage are the most common causes of peeling, with age and wear, poor installation, and chemical damage also playing a role. Homeowners can prevent peeling by avoiding placing hot objects directly on the countertop, reducing humidity levels in the home, using a laminate with higher resistance to heat and moisture, and properly sealing the countertop to prevent gaps. Chemical damage can also cause peeling, so homeowners should avoid using harsh chemicals on the countertop surface. Proper installation and maintenance are also crucial for preventing peeling, as an aging or poorly installed countertop can become more vulnerable to damage over time.
