Flood Paint Additives that Make House Painting Easier

House painting projects attempted by homeowners may initially seem like a piece of cake. Until you get started, you realize that achieving an even finish is more involved than you thought. 

An exterior painter’s mistake could result in a streaky, peeling mess of trim, siding, doors, or windows. A more ambitious job like painting in high heat during summer will require extra steps and planning to avoid paint failure. 


It can be hard to achieve professional results when applying thick house paints. Thankfully, some additives will help elevate any exterior or interior painting project. We often turn to Flood’s Floetrol, a product that transforms acrylic paint, making it easier to apply, eliminating brushmarks, and helping paint level. 

Floetrol will significantly increase paint leveling while decreasing flow issues in a way that confidently inspires your painting workflow.

Floetrol for Water-Based Paint 

Acrylic can be challenging to work with mainly because acrylic paint dries more quickly, causing uneven finishes. The work of an inexperienced painter may be evident with pronounced signs of brush or roller marks, compromising the appearance of the paint. Floetrol is a latex-specific paint additive that aids water-based paint flow and leveling.


Floetrol will slow the paint drying process and improve paint viscosity, making the paint easier to spread and work with. It has no adverse effects on paint durability when used correctly. However, adding too much Floetrol will reduce high-gloss paint finishes.

Adding water to acrylic paint is not recommended. It will reduce the paint’s durability and adhesion properties and alter paint pigments, compromising the paint color.

Advantages of Flowtrol

Floetrol comes in handy for challenging house painting applications. If you’re struggling with the paint dragging while painting interior or exterior surfaces like walls, trim, doors, or cabinets due to fast dry times, Floetrol can make a big difference in giving you more time to smooth the paint out before it dries. It extends how long the paint is wet, eliminating noticeable brush marks and other surface imperfections. 

Using Floetrol for Exterior Painting Projects

If you’re tackling an exterior house painting project, there are even more benefits to using Floetrol. If you live in a hot or cold and dry climate, painting can be complex, as it is often tricky to get a solid coat of paint when the weather isn’t cooperating. The results can range from mediocre to cringe-worthy, so the added help from a conditioner like Floetrol is often essential.

Instead of wasting money on extra paint to attempt to cover up an uneven layer, Floetrol can make your paint materials perform better. The substance will help the paint glide on the surface and extend your time before it dries, allowing you some leeway to correct any mistakes due to painting in extreme heat or direct sunlight.

This paint additive also works well if you’ve chosen to use spray guns to apply the paint. Floetrol acts as a lubricant and will help avoid clogs and wear and tear on paint sprayer parts. 

Penetrol for Oil Based Paints 

Most oil-based paints have a pungent odor, and the potential health and environmental effects are why they’re currently not used often for house painting projects. However, when your house is older, or you are painting metal surfaces, it may be vital to learn how and where oil-based paints work best.¬†


If a home has been painted with oil-based paint, you should not simply paint over it with a water-based formula. Water-based paint applied over oil paints will not adhere and will crack and peel into rubbery strips. 

However, if you want to do a quick paint job but don’t want to waste your money and time re-painting a surface that will quickly degrade, industrial-grade oil paint will offer the best long-term results. Rustoleum oil-based paint is known for its slow-drying properties and its durability. However, it has less flexibility than latex-based paint and is more challenging to apply. 

You may notice that attempting to brush the trim in a room with oil-based paint slows down the process and often leads to hand cramps due to it being more difficult to spread than acrylic formulas. Although there is a relief, Flood offers an oil-specific paint additive that makes brushing with oil paints easier. 

Flood’s first product on the market more than 100 years ago was Penetrol, an oil-based coating additive created to improve the flow of the paint and help it penetrate and adhere better to the surface. It still works well today to smooth out the paint’s consistency, eliminating the appearance of brush and roller marks. 

Penetrol is the best paint additive while brushing any dark color in oil-based paint. 

Enhanced Paint Bonding Properties

No matter what paint you will use, the critical factor to its durability is the bond it forms with the surface. House paint’s ability to bond can be compromised when painting over a chalky substrate. 


A chalking paint surface is caused by long-term exposure to heat and oxygen. Paint chalking is exacerbated by continuous exposure to excess moisture or UV rays, impacting paint binders and pigments, also known as oxidation.

Exterior paint oxidation is most prevalent and is easy to detect. Paint oxidation is well underway when a powder appears on your hands upon touch. 

Another easy way to test for oxidation is to choose a light-colored rag if your wall is dark; conversely, if your wall is light, choose a dark rag. 

Take the clean rag and run it across the wall. If particles of paint appear on your rag, you know you’re working with a surface that is already chalking, and the outcome of your project depends on what you do next. 

You must use a primer for the best possible exterior or interior painting results. Thankfully, this doesn’t need to be a separate step in your house painting process. Flood created E-B Emulsa Bond as a bonding paint additive that painters can use on the first coat. 

Mixing the solution into your paint will also increase drying time. According to Flood, painters who use the E-B Emulsa Bond also generally use 20% less material than if they had applied the paint without the E-B Emulsa Bond. 

Painters should mix E-B Emulsa bond with latex paint. The typical mixing ratio is about 1 quart Emulsa-Bond to 1 gallon of latex paint. You can then apply your paint with a brush, roller, or spray and let it sit for about 4 hours before applying a topcoat. 

This bonding primer is not ideal for use with gloss paints. 

The History of Flood & PPG 

PPG has been in the home materials business for nearly 140 years. The company began creating plate glass in Pennsylvania and acquired an interest in its first paint company ten years later. 

In the company’s long history, PPG has provided glass and paint for automobiles, WWII military aircraft, and early flat-plate solar panels. It developed the protective printing material used in passports and photochromic lenses that automatically darken to block harmful UV rays when exposed to sunlight. 

In 2011, PPG acquired several home improvement brands, including Flood, another long-time business that a family of painters started in 1841. Over the decades, Flood has built a reputation as “The Wood Care Specialist” due to the brand’s specialty wood stain and paint additive products.

Together, PPG and Flood provide products used by nearly half of all paint contractors in the United States. Their products now serve as the secret ingredient for people who spend their days as professional painters and homeowners mastering their first do-it-yourself paint job. 

Are Paint Additives Worth the Cost?

When you’re about to start a house painting project, you might wonder if purchasing paint additives is worth the extra investment. The reality is a paint additive offers a substantial performance increase, decreasing the overall time and effort you spend on your project and the amount of paint you’ll need to get it done well. 

At a minimum, the appropriate paint additive will shave off a couple of steps from your painting process. At most, it will reduce the likelihood of hiring a professional to redo your hard work completely. 

You’ll likely spend years looking at the paint job you’re about to complete. While it’s unlikely you’ll remember forking over a little more money now for the suitable paint additive, you’ll regret not purchasing it if you end up with streaks and flaws in your finished work that you’ll obsess over for years.
