It is possible to laminate over the existing countertop but not recommended. The concern with Laminating over existing is that you need to scratch the surface (belt sander) to ensure a good adhesive bond between the old and new laminate. Even with a wide belt sander it is extremely difficult to get a smooth surface for bonding purposes and the result is a wavy appearance. Old laminate countertops are typically removed prior to re-installation.
This is highly dependant on the design of a kitchen. A basic galley kitchen could be 15 minutes whereas a large U shaped kitchen with chimney notches could take upwards of 4 hours. Installation times overall vary primarily as a result of the amount of miters to assemble and notches/scribing required to fit the walls.
Although laminate remains a great value to consumers, there are other premium products on the market. Granite, Corian and Quartz probably make up 90% of the premium countertop market. Each product has its own features and benefits relative to performance, esthetics and overall value. This final selection of which product is â€œrightâ€? for you is dependant on what you want to achieve in your overall kitchen design.
Some stores carry blanks only. Some can cut them to your required length. You will need a drill, screws, glue, jig saw. We can also sell and cut tops to your required length.
Your countertop should be screwed from the underside. Remove the screws and cut the silicone along the back wall. They should come off easily. If by chance they are not screwed in from the underside, it is possible the the deck was nailed or screwed on before the laminate was put on. If that's the case, the removal will be much more difficult. Then you must peel the laminate back to get at the nails or screws.
Are you positive that you didn't install Marble instead of Granite? If so, then yes, it will tone back down to it's original color. You do not have to wait to seal...most manufacturers suggest waiting only 48 hours before sealing. If you did infact install marble , it is possible that you may have stained it with the thinset...
Depending on the type of adhesive that was used you may be successful by doing the following:1. Reheat the area Lifting - get a blow-dryer and apply heat to the lifted area. Apply enough heat that it is hot to touch.2. Apply pressure to the lifted area - Use a J Roller or wooden block and apply pressure to the heated area. Be careful to apply pressure slowly as you do not want to crack the laminate in the process.3. Allow area to cool.Most Solvent based adhesives will reactivate with heat. If you are unsuccessful then the contractor most likely used a water base adhesive
