Compare and Contrast:
Different house paints have different qualities and are manufactured for different purposes. While outdoor paints are made to combat mildew and fading, indoor paints are made to be scrubbed, allow cleaning, and resist staining. Before starting to paint, it’s important to know the differences between the paints and choose the right one for the project. But what are the differences between outdoor and indoor paints?
Although there can be many other differences between these paints, the main difference is their choice of resin. The resin refers to what binds the pigment to the surface. In an outdoor paint, the paint should be able to withstand temperature changes, especially when exposed to moisture. Also, they should resist peeling and be tough. This means the resin used in binding must be softer. In comparison to the outdoor paints, the temperature is not a problem hence the binding resin is more rigid and cuts down on the smearing and scuffing.
The added resin in outdoor paints can lead to out-gassing that may last for up to 48 hours but usually go on in small amounts for several years. It’s, therefore, not advisable to use outdoor paints indoors. For masonry and stucco, you should choose a flat sheen outdoor paint so as to allow the surfaces to breathe and the moisture to escape. Remember, brick walls should be allowed to breathe since moisture is expected to escape.
In comparison to outdoor paints, indoor paints are delicate but do not often out-gas in the same way making them ideal to be used indoors. However, while painting indoors, make sure that there is enough ventilation. You may need to scrub and clean the surface before choosing a glossy interior paint since they often resist scrubbing much better than the flat surfaces.
You can use outdoor paints to paint your living room or your kitchen but you may not want to. This is because the additives and binders are meant to withstand harsh conditions and the coatings are less decorative and thicker as compared to the indoor paints. On the same note, if you use an indoor paint to paint the exterior of the building it will definitely not last long. The paint may not fade in the sun but it will get destroyed very fast.
