How Do You Deal With These Common Paint Defects?
There are people who really like to paint their homes by themselves thinking that the work is quick and easy. People are always looking for ways to save some money and DIY projects can be tempting ideas. But others do the work for the love of it. If you belong to this last category, there are factors to consider before you even open the first can of paint you’ve bought. If you’re a newbie painter, you have to visualize ahead what would likely happen if you’re not mindful. The professional Perth painter team highlights the common paint defects and how you can deal with them effectively:
Colour Mismatch – When you need to repaint your house, you have to take into account the original colour and the fresh one, and the finish. This problem becomes very obvious especially when you are not entirely repainting or will be doing just some parts. The original finish will changed due to weathering and exposure. Not using the right paint formula is more often than not the culprit. Other factors to getting the right shade are proper stirring technique, and application – ensuring that it is neither too wet nor too dry.
Other top tips to make sure you arrive with the right paint colour include:
• Polishing adjacent panels to check the colour.
• If necessary, follow the instructions of our Perth painting colour guide to match the old finish.
• Spraying technique offers a smoother finish, but before starting, do a test spray on a panel for colour verification.
• Blend the colour into adjacent panel(s).
But what would you do if the surface is the problem? The most that you can do is to sand it and refinish. Nonetheless, remember to pick the right formula, tint it and blend well before painting.
Cracking – This could be a series of defects from hairlines to deep cracks looking like mud cracks in a dry pond. Cracks could come in no definite pattern. The main culprit is application of an excessively thick film. Overly thick topcoats can enlarge normal stresses and strains resulting to cracking even under normal conditions. Another cause could be your uneven mixing of materials or you may have had used additives incorrectly. You may have not noticed that your substrate was too hot or cold. Also, you may have used coats that are incompatible with each other.
But you could prevent cracking to happen by keeping these techniques in mind:
• Don’t pile on topcoats. Allow enough flash and drying time between coats.
• Don’t make the mistake of fanning with compressed air from the spray gun to make paint dry.
• Stir all pigmented undercoats and topcoats thoroughly to get a proper blend.
• Read and carefully follow recommendations of Perth house painters in the Technical Data Sheet(s). Use only additives specifically designed for a colour coat to avoid weakening the final paint film. A weakened film is more sensitive to cracking.Once cracking is obvious, the affected areas must be sanded to get a smooth finish. Or in extreme cases, you have to strip down to bare surface and have a full refinish system reapplied.
