About Latex Vs Oil Paint for Exterior Painting
We know that exterior painting is essential for keeping your house in good condition and making it attractive and unique. You can give your roof, siding, front door, porch, patio, gutters, and deck a new look after doing exterior painting.
Generally, the same type of paint is needed for painting these surfaces. There is a difference only in the application and finish of the paint.
Conventionally, paints are broadly divided into two major categories, i.e., water-based and oil-based.
Water-based paints are referred to as latex, vinyl, or acrylic. Oil-based paints are referred to as alkyd, polyurethane, or varnish.
If you apply paint to any surface, the solvent will evaporate, and only the solid coating will be left. Before proceeding further, we will learn about latex and oil-based paint. Both these paints have their advantages and disadvantages.
Latex Paint for Exterior Surface
Latex paints are based on vinyl and acrylic and can be easily cleaned with water. Latex paints can also be called water-based paints.
In latex paint, the solvent is water. Due to government regulations and consumer demand, there are continuous changes in the paint formulation.
These regulations have led to a change in the formation of paint, such as making more paint solid and using less solvent. There is a shift in the paint from oil-based to water-based paint.
Latex paints do not use organic solvents as their primary medium, so they emit very little VOC as compared to oil-based paints, even if they do not require any solvent for cleaning the tools and equipment after paint use.
Latex paints are used by everyone, irrespective of the professional requirements for them. Homeowners can apply this paint on the exterior walls of their house and can easily clean the tools and equipment used.
Latex has excellent durability and won’t fade quickly. Even latex paint resists cracking on the walls.

However, both types of solvents are suitable for exterior painting and are tough and durable. Oil-based products are adhesive to the surface to which they are applied.
Oil paints are hard to handle, apply, process, and manage after use. It will take at least one day to get the oil paint dry. If the oil paint gets oxidized, the paint can be brittle and crack.
This paint is often used to paint the trims of houses. Oil-based paints have high volatile organic compounds, also known as VOCs, and have an adverse effect on air quality as well as the environment.

What are the ingredient of Paint?
Paint is a mixture of four ingredients. They are binders, pigments, solvents, and additives.
A binder is a natural or synthetic resin, whereas the solvent can be water or an organic solvent. A solvent is a medium that can be water or an organic solvent where binder, pigment, and additives are dissolved.
The pigment will impart color to your paint. Lastly, additives are small amounts of substances mixed into any paint to modify the properties of the paint, like fungicides, defoamers, UV stabilizers, etc.
Difference between latex vs oil paint
When it comes to painting your house, latex vs oil paint for the exterior will come to mind. The most significant difference between latex paint and oil paint is their composition.
Oil paint is a good option when you want to paint the doors, trims, and any other high-traffic areas. In contrast, latex paint is a good option to paint the walls.
Another big difference is that oil paints are harder to apply than latex paints. Oil paint is thicker in consistency, so one may need different brushes or rollers to use.
Since the odor of oil paint is also very strong, one should make sure the area is well ventilated while applying it. And the great part about oil paint is that you can easily get it from any nearby paint store. You can tint your oil paint any color you want to apply.
On the other hand, latex paints are easier to work with than oil paints. They are thinner than oil paint, so you may not need specific types of brushes and rollers. Latex paints are easy to tint any color.
Before applying the oil paint, you may have to use the primer first and then apply the oil paint. However, this is not the case with latex paints.
Oil paint may bubble during the painting process and lead to damaged paint surfaces. In contrast, latex paint won’t bubble during the process.
You can apply one single coat at a time with oil paint. However, you can cover the area faster with latex paint by using a couple of more coats.
Oil paints will take a longer time to dry than latex paint.
Oil paints-are flammable as the binder it contains is very similar to the paint thinner. And latex paints are non flammable as the binder is water and does not contain volatile elements like petroleum, methanol, or ethanol.
Oil paints are harmful for humans and also for the environment as they contain large amounts of volatile organic compounds(VOC).However, latex paints are not toxic and hazardous to the environment .
Latex paint can often be recycled into new paint but oil paint cannot recycle into new paint.
