Polyvinyl acetate emulsions, or PVA's, are the most common example of adhesives that build strength as they dry. As the liquid carrier evaporates, or is absorbed in to the surface involved, the glue hardens or cures, thus bonding the two surfaces together.
PVA - Polyvinyl acetate - the basis of various types of adhesives, paints etc. Often used diluted as a stabilising solution on powdery surfaces.
PVA (Polyvinyl Acetate): A colorless, thermoplastic, water soluble, resinous high polymer
derived from the polymerization of vinyl acetate with a catalyst; used as a latex binder in certain,
generally lower quality water-base coatings.
PVA or drywall primers are inexpensive and high hiding. They provide a tight bond to new drywall, while providing a fairly opaque surface for your finish coat. To tell the difference between unprimed drywall and primed drywall, firmly press a piece of adhesive tape to the wall.
PVA glues have a "chalk temperature" of between 47F and 55F. depending upon the formulation. When the glue "chalks" it turns white as it dries and looses significant strength. So if you are doing glue ups in a cold garage, bring the wood and glue inside to warm up prior to gluing.
~ should never be used with tile adhesive. A tiller's primer should be used, available from any good tile shop.

~ adhesive is useful in many scenarios in which you apply a certain coating to an existing surface. It helps the surface remain workable while you skim it for a longer time because the ~ adhesive prevents the coating over it from drying too quickly.
7. Brush ~ glue onto the drawer front. Adhere paper to the drawer. Once glue is dry, trim the edge with a very sharp blade.
8. Varnish the paper drawer fronts. When dry, sand gently and then apply a final coat of varnish.
~ (polyvinyl acetate) -- It's organic and holds up well over time; it's not related to dangerous PVC.

If you have some ~ (polyvinyl acetate) primer handy use it, otherwise just paint.
If the wall is stippled (textured) matching the stippling is another chapter.
Unfinished, bare drywall needs a coating of primer (usually a type called ~ which is specifically formulated for that material) before texturing can be applied. Then paint can be applied atop the textured compound.
~ is short for poly-vinyl Acetate. This is also a waterborne resin used mainly in interior paints. ~ can be used in exterior paints either by itself, or in combination with acrylic. Exterior moisture resistance and weathering of ~ will not be as good as acrylic.
The material composition consists of a single thin sheet of laminate (typically .030" - .040" in thickness) that gets bonded to a 45# density particle board substrate (or other similar base material such as MDF - medium density fiberboard, or plywood), with a ~ adhesive (poly vinyl acetate - a ...
Numerous manufacturers of masonry paints and primers boast of the addition of poly vinyl acetates (~) to the product to increase adhesion properties.
Sand the area lightly using 150-grit sandpaper. Apply ~ primer. Retexture the surface, if necessary, using texturized paint.
REPAIRING HOLES IN PLASTER
Gently scrape away any loose material and clean the damaged area. Undercut the edges of the hole where possible.
- Sealant such as ~ glue
- A paste or gel like substance such as wallpaper paste, shaving cream or hair gel
- Two 0.2mm plastic bags for asbestos waste
- A disposable plastic drop sheet to cover the floor under where you are drilling
- A sturdy, disposable cup if working overhead ...
A synthetic resin used in the manufacture of water soluble paint coatings. ~ and acrylic are two types of latex resins used to make latex coatings.

Bonding agents (such as a weak ~ adhesive solution) will also aid bonding to existing masonry.
To avoid cracking, it is imperative that mortar is not allowed to dry out too quickly. Avoid applying Stucco in direct midsummer sunshine or very hot/dry conditions.
