Lots of homeowners don’t know whether or not there are differences between exterior and interior paints such as offered by Solver Paints. If you had asked the ‘what’s the difference between exterior and interior paint’ question twenty years ago, the answer would have been ‘not much’. But presently, there is a much wider gap between the two paint categories, and the gap is based on two major features: VOCs and weather conditions. This article offers a rundown of the key differences – and why you should not use the two paint types interchangeably.
Firstly, the basics
The two noteworthy differences between them come down to off-gassing and durability. Exterior paint needs to endure the weather and not peel. From winter snow to summer sun to every single thing in between, the number one quality of this paint is durability.
Conversely, interior paints need not be as strong, though they have to be resistant to daily wear and tear. Interior paints also feature a low level of VOCs (volatile organic compounds). The chemicals can irritate your throat, nose, and eyes, bring about breathing issues, damage the central nervous system and organs, and, in certain instances, bring about cancer. Thus, it isn’t surprising that no one wants them in his home.
Know your paint chemistry
Understanding a little bit about paint helps you know how exterior and interior paint differ. Paint is produced to cover varying surfaces, from drywall to wood to metal. This is among the key things you should know before you start seeking the supplier of Solver Paints near you to buy supplies from. Its main recipe comprises pigments, additives, solvents, and resins. The chemicals float inside the solvent, which is the feature that makes the paint wet. When you roll paint onto any wall, the solvent eventually evaporates, leaving the solids. The pigment, which is attached to the wall’s surface by the resin, produces the colour. Additives could then make the paint resistant to mildew, faster to dry, and easier to clean.
Latex versus oil
Oil-based paint is produced with either oil (normally linseed) or alkyd (a kind of resin). It features higher VOC levels and could off-gas for several years. Consequently, some countries proscribe its use indoors, which then means it is primarily used on exteriors, especially exterior woodwork and trims. Latex is a mix of acrylic plastic and latex (synthetic or natural). The water-soluble combination, both flexible and hard, features low levels of VOCs. It is currently the go-to option for both exteriors and interior.
Exterior and interior latex
Recall the binders and additives that were earlier discussed? That is where latex (or rubber) meets the road. The heavy-duty binders and additives contained in exterior paint are made to endure harsh weather. This ends in a coating that’s thicker than interior latex. Similarly, interior latex, which doesn’t have more durable additives, will not hold freezing snow or a 90-degree heat. The colour will fade, paint deteriorates faster, and you will be repainting much sooner than you desired.
In conclusion, these are the key differences between exterior and interior paints, such as offered by Solver Paints, that you should know. It is hoped that this information helps you in making informed painting project decisions.
