12 Facts about Dot and Dabbing
What is dot and dabbing?
Dot and dabbing is considered a less messy process compared to wet plastering. It is best used for small accidents that do not require the entire wall to be fixed. Sticky dots are affixed on areas where plaster will later be applied. These are made of plastic, vinyl or adhesive paper.
When you consider all the time it takes to remove wet plaster after a large area has been treated, dot-and-dabbing can be considered time-efficient, particularly if the plaster is applied to a small area.
It's a way plasterboard adhesives are applied in even spaces across a wall surface. This process also uses fewer materials and staff can complete their tasks quickly.
How does it work?
The first step is to prepare the wall or surface that needs patching. This entails ensuring smoothness and cleanliness. To ensure this, the surface is sanded before emulsion paint is applied to allow for even coverage.
If you have a large area that requires plastering, then dry-lining is best because it's faster than wet plastering.
Does dot and dab cause damp?
No way. Dot and dab does not result in cracks which can lead to dampness.
How does dot and dabbing compare with plastering?
This method is better than the traditional method that involves plastering overall because it's faster and cleaner. However, this doesn't mean that you can skip the necessary steps of making your wall surface smooth enough for applying the emulsion paint.
Do you skim over dot and dab?
No, you can't. If your surface is uneven and bumpy, then it's not smooth enough for the emulsion paint to stick on. So you need to start smoothing out those spots now by dry-lining or wet plastering so that your finished product will look as professional as possible.
How do you tell if you have dot and dab?
Dot and dab is quite easy to identify. When the wall is still wet, you can see that it's covered in dots or little droplets of paint while the surrounding areas are mostly white. Typically, dot and dab newly applied walls are difficult to colour because it'll require several coats before you can get satisfying results.
Can you dot and dab onto a painted wall?
No, you can't. You can use your finger to try and smooth over the pattern but this isn't advisable because it'll make things worse. You are better off removing the current paint on the wall by sanding it down before repainting it either with a brush or roller.
Is it okay to drill into dot and dab?
Yes, it is ok. You'll just need to apply some fresh paint on top of the dot and dab before drilling so that it doesn't chip up.
What are the benefits of dot and dabbing?
Since it's so cheap, you can change your mind quickly. For example, you might want to have one room patterned in blue and another room in pink.
What are the disadvantages of dot and dabbing?
You won't be able to use many tools with this technique which means that painting geometry will be difficult. The biggest disadvantage is that it may damage your walls.
How long does it take to dab paint on the wall?
It depends on how much paint you will be using and how many rooms you are painting at once, but around three hours.
What is the difference between dot and dabbing and spraying?
Spraying involves applying a layer of primer followed by a layer of paint with an airless sprayer. Dot and dabbing involves using the tiniest amount of paint possible to coat each surface.
What are the benefits of dot and dabbing over-spraying?
It takes less time, is easier to do, produces no overspray. It provides better coverage than spraying.
