These adhesive substances stick a wide variety of materials. Their specificities make all the difference. Before choosing a glue, it is essential to ask the right questions:

  • What object should I paste?
  • What material is it?
  • What is his weight?
  • On which support will it be stuck?
  • Is it indoors or outdoors?

These different products allow assemblies that guarantee a good final resistance. But first you have to know and apply some basic rules. A logical continuation of indispensable precautions, from the opening of the tube or cartridge to the drying time, through a careful reading of the product leaflet.

Old-fashioned glues

Formerly widely used, animal glues (or organic glues) are based on bone, fish or skin. They are still visible in antique furniture restoration workshops. Their advantage? They are "repositionable". Thus, in case of renovation, the bonding can be removed without damage. Today, however, they are competing with chemical glues equally effective.

Read the instructions

Some brands classify their glues by use and not by formula. Thus, some products Pattex or Sader are presented under the name "neither nail nor screw" or "fix without drilling", with variants: external, removable, immediate or invisible.
Disadvantage ? For these multi-purpose glues that have the wind in their sails, difficult to know if it is an acrylic glue, MS polymer or other. Refer to the manual to guide your purchase.

Repositionable assemblies

A repositionable glue

Some brands offer glues in "peelable" version. If you want to disassemble your assembly, whether two days or ten years later, simply insert and gently slide a very flat object between the two elements.
The glue then removes very easily by peeling and leaves no trace on the object or the support.

How to store glues

Keep glue

  • Adhesives perish or deteriorate, even if the tube is not open.
  • An expiry date (DLU) is printed on the cartridge or indicated on the package.
  • The duration of use varies from 12 to 18 months depending on the products. There is no need to buy the cartridges in batches or to make reservations.

Form a plug at the end of the cannula

Once started, a cartridge can not be kept very long. It is best to use it quickly.
If it is not equipped with a screw cap on the end of the cannula, form a cap by letting a little glue escape.
• For small collages, prefer small cartridges (150 ml) or mini-tubes (55 ml).
