PVA glue is the most common glue not only in household goods, but also in the construction industry in general. PVA is used not only in its pure form. Glue is used for fasteners of building and decoration materials, added to putty, paint, etc.
Anyone who first encountered this kind of glue will be interested to know how much PVA glue dries on wood and other materials produced by the pulp and paper and woodworking industries.
What is PVA glue and how is the abbreviation deciphered?
The abbreviations for PVA glue are the first letters of the compound word “polyvinyl acetate”. It is this substance that makes up 95% of the glue. The remaining 5% are different additives, varying according to its purpose. There are several varieties of PVA:
- Clerical (PVA-K) is used to glue paper or cardboard together, often it is chosen for gluing tissue or leather. It can also be used for gluing paper and thin cardboard to wooden parts. Those who are wondering how much PVA glue dries to wood, cardboard, paper, will be interested to know that this particular type of glue is the fastest. Dries up in 15-20 minutes after application.
- Universal (PVA-M) is not a very popular variety of construction glue, since only paper and cardboard are well glued to the wood base. Wood to wood is better not to glue with such glue.
- Universal (PVA-MB) glues wood perfectly. Most often it is used in the manufacture of furniture and other wood products. How much PVA glue of this kind dries on a tree? With proper use, it dries after 2 hours, but for durability it is worthwhile to withstand the glued thing (part, joint) for up to 24 hours, since at different humidity values the gluing time can be different. The best indicator is 60% humidity.
"Quick" varieties
There are many modifications of universal PVA glue. One of these is Moment Stolyar glue. In addition to polyvinyl acetate, it includes special additives and plasticizers that provide better adhesion of parts, water resistance and quick drying. How long does PVA Moment Stolyar glue dry on a tree? Subject to the requirements of the environment (humidity not more than 80% and temperature not less than +10 ° C), full setting occurs after 15 minutes.
Varieties for wallpapering
Wallpaper varieties of glue on a polyvinyl acetate basis, intended for gluing wallpapers, are sold in the form of a dry mixture, which must be diluted with water in certain proportions, which are indicated in the attached instructions. After dilution, PVA glue takes on a slightly viscous consistency that can be easily applied to any surface, whether it is a primer, putty or wood. How much does PVA glue of wallpaper varieties dry on a tree? According to developers and manufacturers, with the correct distribution of glue on the surface of wallpaper and walls, it completely dries out after a day from the moment of gluing.
Conclusion
We think that we have given an exhaustive answer to the question of how long the PVA glue dries on wood and other surfaces. It remains to focus on the fact that gluing / gluing should occur in accordance with the conditions specified in the instructions. In particular, applying glue to greasy, damp and contaminated surfaces will reduce adhesive bonding by an order of magnitude and may extend the setting time.
