There are three types of PVA glue. They are as shown below:
This can be achieved by smearing PVA glue layer over the entrance of the splinter. Once it dries, it will cause pressure over the entry hole. Consequently, the splinter is going to be pulled into the glue. The splinter will then join the glue and once you peel it off, the splinter will also come off.
When plants are pruned, they can be left predisposed to microorganism infections and bacteria that can result to the destruction of the plant. When you leave an opening on a pruned plant, ensure that you apply a coat of PVA glue. This will create an impermeable barrier for the plant and protect it against bacteria.

Having trouble fitting screws into the hole? All you have to do is to pour a few drops of glue in the hole. After that, leave it in for about twenty minutes and wait for the results. Once the glue sets, you can go ahead and screw the screws into the whole. They will fit effortlessly.
To create special effects such as crackles on walls, all you have to do is apply a coat of paint over the wall and give it some time to dry. Once it’s dry, apply PVA glue over it then wait so that it can become gummy. Once it’s gummy, apply another paint layer then wait for the cracking effect to start appearing. For best results, use a base that contrasts with the topcoat color.
PVA glue mixed with liquid starch and food color will produce a cheap supply of slime that you and your children can enjoy for a long while.
