Hi . You can paste it again with epoxy glue. being glued and propped up, you cross hardwood slats from below 2 if it is a single bale or 3 if it is double, against the wall the amuras and the other end you screw it to the front of the furniture and with that the bacha is glued and supported on the slats , you can use it without fear does not fall any more comments comments greetings
Almafrida, you will have to put the adesivo and prop it down with lumber cut to size to hold it while the paste dries
In the case of not being able to turn it around, the area should be cleaned thoroughly by removing all loose and loose parts, cleaning with common alcohol and putting a generous line of silicone sealant on the edge of the pothole. Place it in its place and immobilize it from the floor to its base. You can do it with two pieces of wood or two sections of broomstick. Measure the distance between the base and the floor before placing the silicone. Leave a minimum of 24 hours for the sealant to cure well. Next step would be to prepare plastic putty and place it.
You must do this by overlapping 50% of the lip of the bacha and the marble. The putty is placed as any of its previous type having added its hardener or catalyst. Follow the manufacturer's advice for a good work result. Once the putty dries (the drying time depends on the weather and ambient temperature but in a couple of hours it is well cured) it hardens like stone. It is really hard and tough. I give you a picture of how the putty should be around the pothole.
If you respect the curing times of the products, the final work will last without problems. What if, use good quality products. You can buy putty in any hardware store or paint shop, it is not very expensive. One of the best brands in it is the "TRIMAS". Regards
I forgot, the photos are of the bacha with sealant and the other is how it is with the putty. While this is easier and neat turning the table you can do it without problems with the marble as it is. Remember to clean / dry all surfaces well (apply heat with a hair dryer to remove all moisture) since there will always be traces of grease and water in the area.
