Preparing for Painting is a lot more than picking out a colour and buying some brushes. It takes some time, effort and planning but it will ensure that you get a finished product that will please you for years.
The experts over at Home-Dzine have a wonderful selection articles on preparing for painting. They have are guides on preparation for painting, how to paint almost any surface, and painting tips to save you time and money among many others.
There are of course some common themes:
Keep it clean
You want the surface that you are applying paint to, to be smooth, clean and free from any grease, solvents or loose particulates. Sand your surface if necessary and brush off dust and other loose bits. Give it a wash with the appropriate detergent and rinse very thoroughly. Let it dry completely, which brings us to…
Moisture is your enemy
Moisture doesn’t work well with paint, even water based paint. Dampness on your painting surface can interfere with the paint’s ability to adhere to surface. This can leave to peeling, blistering, mottling and other nasty effects that will ruin your hard work
Make sure you use the appropriate sealants and primers for your surface. Sealants give you a non-porous surface that won’t absorb your paint. Primers give your paint something to stick to. You want your fancy top coat to be on your surface not in it and stuck to your surface not peeling off it. Primers can also include ingredients to prevent your surface from rusting or rotting under the paint. Priming can save you money in the long run as primers are generally cheaper than top coat paint.
Though it make seem like a lot of work and waste of time properly preparing your surfaces will give you a much better result that lasts longer. Proper preparation means that you only have to repaint when you get tired of it not when it gets tired of you.
