Tips on high-quality gluing for furniture

It’s clear that the manufacture and subsequent modification of furniture can only be achieved with the high-quality use of adhesives. This applies to gluing together individual parts as well as gluing on furniture edging. What type of glue do you need to choose, however, to achieve the best quality bond?

The term ‘gluing’ refers to the binding together of two different surfaces using adhesives (glue). The adhesive must adhere well to both surfaces. Every adhesive must always be in liquid form, during the application, since this is the only way to ensure perfect adhesion to the surfaces of the material being glued.

 

Gluing different materials

If you want to glue together different types of material, such as wood, metal, stone or other synthetic materials, it’s good to use a construction or mounting adhesive, e.g. one with a polyurethane base. This type of glue was once most commonly produced as a multi-part adhesive. In recent times, however, it has been made as a one-part adhesive, which means it does not have to be mixed together, but retains nonetheless exactly the same useful properties. Since this type of glue reacts to moisture in the air, simply apply the adhesive to one clean gluing surface, and, after exposing the adhesive to the atmosphere, fix the second surface into place and press together the join. 

For binding together these different types of furniture surfaces, Hranipex manufactures a one-part polyurethane glue – HRANIPUR, which does not contain any solvent. This glue comes in two variants, which differ according to curing time (HRANIPUR-15 cures in 15-25 minutes, compared to the 25-45 minutes taken by HRANIPUR-45).

 

Dispersion adhesives – solutions with greater damp resistance

If you want to glue objects that require greater resistance against damp, e.g. windows, external doors and outdoor furniture, then it’s best to use dispersion adhesives. These types of glue, however, require that at least one of the glued surfaces is absorbent, since the bond will only achieve maximum quality if the adhesive is able to soak into a porous material. 

For these more demanding these types of bond, Hranipex manufactures the dispersion adhesive HRANICOLL D3, with improved heat resistance. This universal adhesive is suitable for binding not only hard or soft woods, but also particle board and other wood-based materials, such as parquet flooring, laminate flooring or veneers. 

The appearance of top-quality furniture and its long-term durability is decided by the smallest details, all of which are visible at first glance. Which is why you always need to use the most suitable manufacturing resources – including the correct choice of adhesive - whenever making or renovating furniture.
