What adhesive should we choose to achieve the expected strength and finish?
These are some of the questions that arise when choosing the right glue with which to join marble, porcelain or granite. These products are among the most demanded in the sector, by marbleists or sculptors, which they use daily. The most demanded chemical characteristics in these adhesives, are that after hardening they acquire the properties of the stone, as well as its hardness and color.
The formats in which we can find these adhesives depend a lot on their composition, use and application. On the one hand, there would be liquids and on the other the solids that exist in putty, paste or silicone format.
Within these two divisions are the monocomponent adhesives, which do not need the help of a hardening catalyst, and two-component adhesives, which do need a catalyst that with their mixture causes the hardening and appearance similar to that of the stone.
Types of adhesive:
In the market we find them for sale with different chemical formulas such as putties, silicones, resins, pastes and glues:
Epoxy: It is an epoxy or polyepoxide adhesive, which is a thermosetting polymer that hardens with the mixture of a catalyst or hardener.
Polyurethane: This type of adhesive has its chemical base in isocyanate. They are characterized by being elastic during application and high rigidity after drying which gives it resistance.
Polyester: The chemical base of this adhesive starts from the elastomer, which is characterized by its flexibility and transparency.
Catalyst: It is the chemical component that certain adhesives need and that causes the acceleration in the hardening process of these. This brings hardness, but does not alter the appearance and final result.
Indoor or Outdoor and Vertical or Horizontal Application
When choosing an adhesive or another, the first thing that we must take into account is the place where that piece that we are going to join will be placed. If it is the covering of walls and therefore a vertical work, the use of putties is the most advisable, allowing its molding. If we work on the union of a countertop, the glues or liquid glue are more manageable and cover the pores. Most of the adhesives on the market withstand normal humidity and temperature conditions, but in many cases the coating will be subjected to extreme situations and therefore we need a more specific glue, with epoxy and polyester based ones being the most suitable to withstand large thermal expansion and high humidity situations.
Color or transparency
Another element to take into account are the type of finishes of the joints, visible or hidden joints, hollows … At present there is a wide variety of products that allow you to find the color that best suits that of the stone. In the restoration work the most convenient is the use of transparent products. These adhesives will go unnoticed, offering a clean, transparent and colorless bond that guarantees a less impressive result. This type of transparent putty is what is commonly used in Travertine marble to fill gaps that make it so characteristic. A solid color mixture will be perfect in the case of porcelain, quartz or granite if we want the board to go unnoticed. In addition, after its application we can polish it like a normal stone, obtaining a shine and transparent natural transparency.
