Paint technology has moved on! Colour saturation and chemical discolouring are issues that you will experience over the years. Modern paint is chemically more balanced to retain colour and prevent discolouration. The main reason for the discolouration as a historic problem is the oil content in the paint. New chemical compounds have made the paint a lot more stable but they can still be oil based.
Oil based paints are slow drying and quite often have a smell that takes a few days to disappear and only once the paint is fully dry and hardened. These two factors can be a consideration for any project as rooms should be well ventilated and traffic kept to a minimum until fully dry. There is nothing more annoying than someone brushing past a painted surface destroying the finish you have painstakingly created but also the individual who now has paint on their clothing which is difficult to remove.
In the warmer summer months you have the added annoyance of insects, dust and pollen which can spoil the finish. The other major issue is the dreaded drip which can harden as a teardrop on the surface.
The following are some of our tips when using oil based paints.
It’s very important to sand surfaces before painting them. Sanding will provide a key for the primer and it will smooth out some of the imperfections from previous coats of paint. Light sanding between coats will prevent drips, speed up the drying process and help you achieve a nice even finish.
Working with Grain
Painting with the grain will ensure that the spread of the paint is much more effective. It will also help eliminate brush strokes.
Using primers is an ideal way of obtaining good adhesion, especially where the application is to new or bare surfaces. We recommend quick drying solvent based primers, providing an ideal base for additional coats of paint.
Using brilliant white versus a mixed colour will make a difference to the number of coats needed to obtain the finish you want. Typically, the white will require additional applications compared to a coloured paint.
Understanding the surface you are painting is important and using the correct paint and preparation is fundamental. The finished look of the paint will vary from surface to surface depending on how smooth or rough it is and what level of sheen content is in the paint.
Price does matter! Using a professional paint or trade paint will be much more cost effective in the long run. Trade paint is much better than DIY paint. It has more pigments (the coloured dyes) in it, meaning it will have better opacity and take less coats to cover, producing a far better job. It should also last much longer than the DIY equivalent which is produced for easy application and frequent recoats.
In conclusion, we would strongly recommend planning your project, take time to prepare the area and select the right paint for the effect you are trying to create. Equally, do not rush the project allowing appropriate time for the paint to dry between coats. If you start a job and finish it 4 hours later and the manufacturer recommends 8 hours between coats, you would be well advised to wait until the next day to apply the next coat. Hot and cold temperatures will affect the advised drying times. Ditto humidity.
