As part of a plating or a multi-material assembly, neoprene glue remains the most popular. This is why it has become the essential ally of all DIY enthusiasts. Focus on its specificities.
Presentation and particularities of neoprene glue
Neoprene glue is characterized by its strong adhesion. Also called contact glue, it is used to fix metal panels, laminates, veneers or plastic foams. In fact, it adapts to all types of support whether wood, metal, leather, porcelain, PVC or glass.
This is an excellent alternative when it is not possible to nail or screw a support. This glue is very popular in the world of DIY because it preserves the flexibility of the material and can be used even on very large surfaces.
Choosing the right form of neoprene: gel or liquid
In the trade, it is sold in different types of formats. In domestic use, the tube model will do the trick. But for professional use or in the context of gluing a large surface, it is better to opt for the model packaged in a cartridge and delivered with a gun or the glue in a pot.
Neoprene glue is also available in two different textures. On the one hand, there is the gel that does not drip and is used mainly on false ceilings or vertical surfaces. The second format comes in the form of liquid glue which is particularly suitable for horizontal supports.
Once the right glue has been chosen, the next step is to glue the material itself. But before, make sure to clean the support well and let it dry if necessary. Because you may have a very adhesive glue, its capacity will be limited on a dirty or wet surface.
Once this point has been checked, coat both surfaces with the product using a spatula or a spray gun. Do not forget to wear a mask protecting your nose and mouth so as not to breathe in the fumes of solvents. Wait between 5 to 15 minutes. Touch the backing to check that the glue no longer follows your finger. If so, proceed to gluing the two surfaces. Apply strong pressure for a few seconds. Normally, you will have to wait three days before the setting is final.
The limits of neoprene glue
Neoprene glue has many advantages. But it also has certain disadvantages that must be taken into consideration at all costs. First of all, it has trouble resisting humidity, so it is not recommended on exterior surfaces. Its capacities are limited on some materials such as polystyrene, flexible PVC, polypropylene or polyethylene. Polluting and irritating, this glue must always be used in a well-ventilated place.
Beware of confusion
Attention, be careful when choosing the product. There are neoprene-type glues sold on the market that have nothing to do with the neoprene glue itself. The composition of the two products is different. This confusion can lead you to choose the wrong glue, the so-called “neoprene-type” one which can be cheaper but not very effective.
