Before you can paint your home, you have to protect it from the sun, rain, and wind. With over a hundred years of experience in the field of painting, our experts know just what prevents these elements from destroying a painting as soon as they get a chance to see it.

In order to prevent moisture from penetrating into your walls and damaging your drywall baseboard paint job, we recommend leaving plenty of space between the wall and the ceiling.

If there is no ceiling, leave this space open so that any excess water can drain out. If there aren’t any walls to speak of, then leave them empty so that any excess water can drain away before getting on to your real home improvement project.

You can choose from two main types of wet sand spray paint: solvent-based and oil-based. Each has its own pros and cons which guide us towards choosing the best kind for our homes.

What Is A Solvent-Based Wet Sand Spray Paint Job?

A solvent-based wet sand spray paint job is the easiest project you can tackle. All you have to do is mix up a slightly acidic, water-based paint with high-strength, water-based enamel and baste it into the drywall.

This is the recommended method to achieve a wet sand spray paint job, as it allows you to easily see if the paint has penetrated the drywall and, if not, what parts need sanding.

If you are working on a project with a wooden or painted sub-floor, you will also have to remove any existing drywall and plaster to make way for the new paint. This is usually the case with renovation projects that involve a fresh coat of paint.

What is an oil-based wet sand spray paint job?

What Is An Oil-Based Wet Sand Spray Paint Job?

An oil-based wet sand spray paint job is easier than a solvent-based job, as you do not have to worry about damaging the wall structure. All you have to do is apply a base coat of oil-based enamel, followed by a dry sanding and buffing process to achieve a durable, scratch-free finish.

This is the most popular type of wet sand spray paint job, and it is ideal for contractors who are investing in their own home improvement projects or who want to conceal changes to their homes.

Which Should You Choose for Your Home Improvement Project?

For our recommendation below, choose a solvent-based paint job for concrete, stone, and other drywall-like surfaces. These paints are known for their flexibility and easy application, which means that you can smoothly coat the wall with little or no masking. If you want to avoid masking, then a paint-like epoxy, which is moreonica and semi-hard, is ideal for these surfaces.

Concrete and stone are both examples of hard materials, so you will want to choose a paint that has the ability to bond well with these types of surfaces.

If you are painting a wooden sub-floor or a painted ceiling, leave plenty of space between the wall and the ceiling to allow for any air circulation from the ventilator in the roof to reach the drywall and remove excess water. If there is no ceiling, leave this space open so that any excess water can drain out.

Dries quickly – You won’t have to wait long before your new wall colors are completely dry, even in the winter. This means that you can start your design and decoration process right away.

Protects drywall and wood ceiling finishes If you choose the right type of paint, it should be able to protect your wood or drywall finishes from the dirt, grease, and water that cause so much trouble for other home improvement projects.

Maintains a high gloss finish – Most paints have a high resistance to chipping, flaking, and cleaning. This means that you don’t have to scrub your walls and ceilings too hard in order to maintain a high gloss finish.

Ideal for large projects – If you are doing a large project such as adding new kitchen cabinets or a bathroom, you can hire a professional painter to complete the job for you.

Disadvantages of a Wet Sand Spray Paint Job

  • Expenses – The price of a wet sand spray paint job is significantly higher than a standard drywall paint job. This is because of the materials, paint type, and application method.
  • Excessive water intrusion – Water is one of the primary causes of moisture intrusion in buildings and walls. If there is too much of it in your walls and ceilings, you will have to spend time and money fixing it.
  • Noise and dust issues – When painting inside, the sound of the adjustable sandblaster and the dust created by the operation can be a nuisance. To get the best effect, use a good vacuum cleaner to get rid of excess dust.
  • Fragile drywall finish – While most drywall finishes are painted over a sturdier base, a bare drywall finish can be easily scuffed and chipped by the sandblaster.

How to Achieve the Best Effect with a Wet Sand Spray Paint Job

When painting a wooden surface, use a thin coat of primer to ensure a consistent finish. For a painted sub-floor, use a paint that is easy to work with and provides a scratch-free finish. For a painted concrete surface, use a paint that has a high bond with this type of surface.

For a painted steel surface, consider using a rust-resistant, oil-based enamel that has a low odor and easy application. For a painted drywall surface, use a paint that is meant to be dry-fitted, such as drywall enamel, which will require you to cut away excess material when the paint is applied.

Conclusion

No home improvement project is alike, so it pays to get advice from a professional. When painting your home, choose a reliable contractor with experience in painting both wet and drywall surfaces. That way, you will have a better chance of achieving a beautiful finish.
