House painting projects can be really stressful, and sometimes, it’s not that fun as we think it is. Though interior home painting – covering smaller areas – is another story, exterior house painting tend to appear to be downright unfriendly. A lot of conditions – including the condition of the surroundings – should be taken into account before proceeding with the project, and when this conditions aren’t taken into consideration, then expect that your home painting project will give you an undesirable result. To give you an idea as to why some painting projects usually fail, here is a list of important things that’s often forgotten as the project progresses.
1. The unfinished siding was exposed to sunlight for several weeks before being painted
Extreme sunlight exposure degrades any unfinished wood surfaces, restricting it to hold paint as well as fresh woods. If ever the unfinished wood siding is exposed to extreme sunlight for more than 3 to 4 weeks, power wash or lightly sand its surface to remove the layer of degraded wood before coating it with paint.
2. The temperature was too cold when the wood was painted
If you’re using oil-based paints, keep in mind that it should be applied whiel you are engaging a Singapore painting service for hdb and when the temperatures are at 40ºF; for latex, it should be at 50ºF. Also, remember that the conditions should remain in or above the stated temperatures for 24 hours after painting, and if you plan to pretreat the wood using a paintable water-repellent coating – which is a recommended practice by those in the painting services – do it on times wherein the temperature is at 70ºF to achieve the best result possible.
3. The wood was too hot when painted or was heated after being painted on
Given the sometimes extreme temperatures in Singapore, it can be quite challenging to prevent temperature blister from forming, but to avoid temperature blisters – in a way – don’t do paint jobs when the temperature is at 90ºF or avoid painting surfaces that will be heated soon. The best procedure that even painters suggest is to “follow the heat of the sun around the house”. Paint the east side of your house late in the morning, the south side during mid-afternoon, and the west late in the afternoon. The north side on the other hand, can be painted any time of the day that you wish to.
But do note that at least 2 hours is needed for a fresh paint to dry up before the weather reaches the cooling point that allows dew to form. In case wood blisters would surface, simply allow the paint to dry up for a few days, lightly scrape off the blisters, smooth out the edges using sandpaper and repaint the area.
4. The house doesn’t have an interior vapor barrier
Problems of high humidity level inside the house and woods that were installed directly over foil-faced or foam insulation board can be pointed out to the absence of an interior vapor barrier. The easiest solution to this could be driving the wedges under the sidings. For the upper floors of a multistory house, applying a certain interior vapor or installing electrical outlet gaskets might work. If you’re having problems with the installation then don’t hesitate to call painting services businesses and ask for assistance.
5. The wood sidings are dirty
If ever your wood sidings are quite dirty, have its surface power washed or cleaned using a detergent and a stiff bristle brush then rinse it well. Don’t try using iron or steel to clean the sidings since it will just cause more iron stains and might even graze its surface.
6. Some brown stains appeared on the paint’s surface
Paints don’t need to fall off to fail your painting project. The moisture that’s traveling through the wood is already enough to pull water-based extractives through the paint and leave brown stains on the surface. If the wood that you used has been kept dry, the extractives in the wood will probably not bleed through the paint’s surface. But keeping moisture out can be difficult, so to effectively block out the stains produced by moisture, experts on painting services suggest that you opt for oil-based primers instead of latex. If you don’t have any problems concerning moisture, then latex primers would work well for your walls for they produce paint films that are more flexible and durable.
By becoming aware of these reasons and mistakes, you can now counter and prevent each of them by following the home painting rules that even Singapore painting services providers abide to. With this you can – in a way – already have some fun doing your painting project.
