PVAC glue for wood furniture.
PVAC (poly vinyl acetate) glue is one of the adhesive that
is most widely used in the woodworking industry. The glue is made from the
polyvinyl acetate, the same material to make plastic. The PVAC glue is safe, non-toxic material, easy
to be used with good gluing result. It is water based, that uses water as its
main solvent, so he is very safe, non-toxic and very easy to be handled.
This glue is the one component, make it is very easy to be handled, storage and used. It is dry with
evaporation of his water, and when he is dry he will harden and produce a
strong thermosetting bonding. Soon it is dry it won,t be dissolved with water or solvent, then it can be
finished without the less risk off the glue dissolving. It
is widely used to unify wood pieces in the: laminating process, finger joint and
the assembling. With the right process, then it would constitute very strong
bond.
Since it is water based then it takes
longer time to dry. The drying time is varying depend to the solid content and the
type of the glue usually is varying from 30 minutes to 1 hour. During it is drying, the unified wood pieces must
be hold and pressed to keep tightened. The
pressing apparatus or machine either the automatic or manually is needed in the
application.
The PVAC glue can also be used to form
the texture effect in the wood finishing. PVAC glue can be used alone or mixed with latex
paint and be applied as the texture paint.
the wood pieces are laminated and pressed
Here are some tips to use the PVAC
glue
- Read and check the technical data and specifications of the glue
There are many suppliers of PVAC glue,
each of them may offer their strong advantages and superiority, but each of
them also may need special treatment. Therefore, when we are going to use the
glue, we must have read the technical data and specifications as well. Follow
the instructions of how to use of the product. We need to read the data about the recommended
concentration, pressure, and drying time required. Every wood species often has different
properties and require a different process. Check the instruction of use according
to the wood species if any. We may need to do some trial to get the best result.
Wood also will shrink and swell when its moisture content changes. Since that, the wood pieces that are glued and unified need to have uniform moisture content. Too high variation in the moisture content is risk to create too much wood movement and make the crack or delaminating of the wood.

- Clean the glue excess at the surface.
- PVAC glue is not suitable for outdoor use.
Wasp dudes! Amazing stuff continues the good work.
