Have to do some painting? Before you start, I got some tips to share. Hopefully they can help you complete the task at ease.
Purchasing From The Paint Shop
There are colours catalogue for us to choose our desire colours. Some paint shops will even give these catalogue FOC to their clients.
These colours supposedly shall resemble the actual ones. However, these colours are printed on and not painted. And further more, they are printed on cardboards. So we can't compare what was on the cardboard and assume that the same colours will appear on different surface.
The colours shown is quite close to the actual one. As in the sense, red is to red, blue is to blue, etc... The difference lies in the tone.
Even the same can of paint will have different feel on concrete wall, wooden door and metal frame.
Paint are available in 1 litre and 5 litre can. 1 litre of paint will cost about SG $25. Purchase a larger volume of 5 litres will cost around SG $75. That was a huge 40% off. (Pricing are based on author's experience, may varies.)
So it is much more worth it to purchase larger can. However, do take note of how much paint was needed. Spending $75 to buy 5 litres where you only use 2 litres won't be a wise decision either.
If you thinking of storing the paint for later use, it might have dried up by then. Anyway, don't expect the paint to be as good as new when stored for a long period. So do plan before your purchase.
As a guide for your paint procurement, a wooden door (front and back) will need 1 litre of paint.
Tips For Painting
1. Be patient - Remember "haste make waste".
2. Be Tidy
3. Get a good brush. If you can't finished the jobs in one day, submerged the brush in thinner for reuse on the next day. This will prevent the brush from hardened. Personally, I prefer nylon over natural hair brushes. Reason being natural hair brushes will shed. It will be an eyesore seeing these brush hairs sticking onto the finished paint work.
4. Before we began painting, we need to make sure the surface to be painted is dust-free. Wipe or sweep off any visible dirt.
5. For signboard or artifact, that required a higher standard of finishes, we can use Turpentine to wipe the surface. This will achieve a cleaner surface for painting.
Note: Thinner can "bite off" paint, so we can use them to clean off any accidental spills. But we shall not use them to clean the finished piece, as they will corrode off the paint. If there is a need for cleaning of the finished piece, use turpentine instead. Turpentine is less corrosive than thinner.
Paint For Signboard
Signboard makers rarely use the catalogue from the paint shop, as they follow another type of paint matching system - Pantone.
Pantone has a wider range of colours for selection. Having more selection means we can have a more tailored colours. Especially, in defining corporate colours, we got to be more precise.
Pantone is also widely used colour matching system among graphic designers.
It got to be a uniform standard of colours used among all the vendors, especially if the colours are tied with the corporate identity.
Seem graphic designers use Pantone colours, large format printers and signboard makers will have to follow suit, they will have to follow Pantone.
So signboard makers won't be able buy those colours off the shelf. They will have to mix their own paints, coming up with colour that closely resemble to the chosen one from the Pantone.
A set of Pantone colour chart can cost around SG $200. Did the price stunned you? I was totally astounds by that. After confirming with a few signage suppliers, yah, that's the price. So I don't think any signboard makers will want to give them away for free.
If you do really find any supplier, who is willingly to offer the chart for free, do share with me. I have been hoping to get it. That will be a bizarre wish for a Christmas or birthday gift. LOL.
Communicating With The Signboard Maker
Inform the signboard maker the chosen Pantone colour codes and they will be able to construct your signs. And of course, give them your logo design file too.
Not sure of the Pantone codes? Then just tell them the CMYK codes and they will try to match them. If you are still lost or you just want to ensure the right colours, you can borrow the chart from them for selection.
Painting Method For Signboard
Signboard makers usually will mix these required colours into small containers and then using spray gun spraying the paint evenly onto the signs.
Why Spray paint is Chosen Instead Of Brushing?
1. It create a more even, uniform coat throughout the whole painted surface.
2. It produce a thinner coat which will dry faster than thicker coat.
Drying time is not linearly proportional to the thickness of coat. The drying time needed exponentially went up with thicker coat.
So we will rather paint 2 thin layer of paints than 1 thick coat. This will save a significant amount of waiting time.
Why Paint Drying Time Matters?
Under normal circumstances, a spray paint will take 10 to 20 minutes to reach surface dry. For brush painting, it takes half an hour and even up to 4 hours, depending on the type of paint used, latex, water or oil based.
We are talking about surface dry only. It will take even a longer time for a hard dry.
Signboard being the face of the organisation, is extremely important. With fast drying process, lesser chance dirt will dropped onto the surface, while the paint is still wet.
If any dirt fall onto the wet paint, the dirt will stick onto the surface. Once the paint dried, removing the dirt then, won't solve the problem. There will be a dent on the spot where the dirt perviously rest.
We can't possibly be safe guarding the paint until it dried. So the best practice, is to paint with fast drying paint and method. And a clean dust-free area will be a ideal place for painting.
Another benefit of fast drying is that the production time will be shorten. Thus, the signs can then be delivered to their clients earlier. No clients will like to wait long for their signboard to be deliver.
Spraying Painting Art
Before we end this post, we will like you to watch below video. Using spray cans, this artist create a beautiful image of Rome. While you admire his talents, do take note of how fast spray paint dry.
He had completed his art in less than 7 min. That is an unbelievable speed for such a nice piece of work.
Once completed, without delay, he handed over his work to the customers. Had the paint dry? What is your guess?
