These are a group of 100% solid adhesives (they do not contain water or solvents) that are heated and applied while melted. They quickly recover their solid state, which makes them fast, flexible and durable glues for all types of materials.
Due to their characteristics, hot melt adhesives are widely used in automated machines for industrial processes, but domestic users can also use them with hot glue guns loaded with glue sticks like our RB-1100 and RB-1200 adhesives.

It’s not possible to give a general answer to this question, as multiple factors can influence a glue’s drying time, such as the amount of glue applied, the dryness of the materials, the environmental conditions, the stress of the materials, etc.
Some glues are formulated for faster drying, and when properly applied, glued materials can be handled after a few hours, although ideally the parts should be kept clamped together for at least 24 hours.

First of all, it’s important to remember that most outdoor-use woods are hard or resinous, which poses different challenges when it comes to gluing them.
European standard EN 204 determines which durability classes outdoor adhesives must meet, and classifies them into four grades from D1 (indoor use) to D4 (outdoor use).
D3 WHITE GLUE is suitable for outdoor use and can be improved to D4 with special additives.
PU-500 single-component polyurethane adhesive has the highest category (D4) and is ideal for outdoor use.
Other mixed adhesives and sealants in our range are also suitable for outdoor use.
In all cases, the use of protective varnish is recommended.

White glue can be removed with a damp cloth until it has dried.
Once dried, how you remove it will depend on the material it’s been applied on. You can sand it off of wood and other porous materials, and you can use a solvent like acetone to remove from other materials.

Contact adhesives are uniformly applied to both surfaces using an A1 serrated trowel, brush or roller. The solvent they contain must be allowed to evaporate completely until dry to the touch (approximately 10–15 minutes). Once the solvent has evaporated, you can proceed to join your materials by applying pressure across their entire surface.

No, you can’t rectify mistakes made with contact adhesives. You have to make sure you position your pieces correctly from the start.

No, as their name indicates, these types of adhesives work by means of contact between the two pieces or surfaces to be glued; you therefore have to apply the product to both of them.

Before laying it, apply Sella-fix for laminate flooring  in the joints, which will prevent leakage into the interior when mopping floors and subsequent swelling, etc.

Novosil Sanitarios  includes a fungicide, which prevents the gaps between tiles from turning black due to fungal growth as a result of humidity.

Before drying, spray on Novopren cleaning solvent  and then wipe clean with a cloth. Don’t let the foam dry, otherwise it can only be cleaned by mechanical means.

You can use Eliminacola to soften it and then remove it with a putty knife or paper. Just apply it to the unwanted adhesive and let it sit for about 15 or 20 minutes before removing. It’s a good idea to scrape the dried adhesive down to as thin as possible first so the glue remover will work faster.

We have a unilateral adhesive that is applied with a roller instead of a serrated trowel, making it very easy to use: Primacola C-20

If you do not have to use all of the spray, remember to turn the container upside down after use and press the nozzle until only gas comes out, so that the nozzle is clean for later use.


Some adhesives can present risks to the user and there are danger and caution statements that must be observed. Fortunately, each product has a complete safety data sheet that will allow the user to take precautions for use and know how to act if an incident occurs. Always follow the instructions on the labels and do not hesitate to request the safety data sheet for the adhesive.

Depending on the type of product to be handled, additional protection elements such as gloves, glasses or a mask will be required. We invite you to consult the safety recommendations for each product and follow the instructions.

The place must be well ventilated. We must not produce any type of spark or flame while we are using it (smoking, welding, etc.), the minimum working temperature must not be less than 10ºC. and the precautionary instructions indicated on the adhesive label and safety data sheet must be followed.
