Floetrol – What Is It? When To Use It: Complete Guide

Ever get a build-up of paint marks on your paintbrush that are hard to remove? This can be frustrating, especially if you want to use the brush right away.

But, rather than discarding the brush and having to spend money on a new one, there are ways to reduce the build-up on the brush and continue to use it.

Floetrol - What Is It? When To Use It: Complete Guide

How? By using Floetrol. Floetrol is a type of latex paint additive.

It is mostly used as a conditioner on paint brushes to reduce any build-up of materials on the bristles and handles.

It can also be used to extend drying times and erase unsightly brush marks.

Considered to be a secret weapon by many painters, Floetrol provides latex paint with a similar leveling and flow to oil-based paints.

Floetrol should not be used to thin paints, contrary to popular belief. It is best when applied to a semi-gloss, flat, or eggshell sheen.

It has a milky tone and dries clear, meaning it should not alter your paint’s color. And, when used on a high gloss sheen, Floetrol can help to minimize the overall shine.

Want to find out more about Floetrol? You’re in the right place! In today’s article, we will be discussing exactly what Floetrol is and when you should use it.

Therefore, you can utilize it for certain projects and benefit from its effects.

Floetrol: What Is It?

Floetrol, made by Flood, is a paint conditioner, often used with water-based paints, such as semi-gloss latex, flat, acrylic, vinyl, and enamel paints.

Its formula allows such water-based paints to act more like oil-based paints.

Therefore, the paints are then easier to use, rather than being too heavy and less forgiving when sprayed onto surfaces.

Moreover, latex paints tend to leave roller or brush marks behind when applied, but Floetrol can also minimize or even prevent such marks.

All in all, Floetrol is used to make your painting life easier.

When Should You Use Floetrol?

In general, Floetrol is typically applied to doors, cabinets, trim, or finely detailed furniture when painting. It is usable indoors and outdoors and can be applied in several ways.

If you can’t use a brush or roller on the surface you are working on (i.e. the paint sets too fast or drags), then this is a good time to use Floetrol.

But, to get the best results, you should always use a top-quality brush. One issue many people have when spraying paint is a build-up of paint.

Sometimes, the tip of the spray applicator can clog, and the piston can freeze up on cap gun sprayers. Floetrol can reduce this clogging and prevent the piston from seizing up.

Therefore, your sprayer can enjoy a longer lifespan and you won’t have to spend your hard-earned cash on a new one every so often.

Furthermore, Floetrol can help you achieve a consistent spray pattern.

How To Use Floetrol Correctly?

If you have never used Floetrol before, there are some tips to keep in mind. Firstly, we recommend experimenting with various amounts to check their impact on the paint.

This is because a little Floetrol can have a big impact, whereas, at other times, you may need to use it a lot.

The best way to start is with half a pint of Floetrol per gallon. If the paint continues to drag or starts to set too quickly, you can add more as you go along.

But, you should not use more than one quart of Floetrol per gallon at any time. If you exceed this, Floetrol will lose its ability to conceal its appearance effectively.

Here’s a quick tip – we suggest that you add in the right amount of Floetrol you need and have someone at your local paint/hardware store prepare it using a paint shaker.

This will mean it is ready to use when you need it. Here are the basic guidelines on how much Floetrol to use, based on the applicator:

  • HVLP spray guns – in general, you should typically add 16 to 32 ounces of Floetrol per gallon. Start with the smallest amount and increase gradually to not overly thin the paint.
  • Brushes and rollers – can mix up to 8 ounces of Floetrol per gallon. Again, start with small amounts and increase gradually if needed.
  • Airless paint sprayer – generally, you should mix up to one quart of Floetrol (32 ounces) per gallon of paint.

Keep an eye on the paint you are working on. If the flow seems to be in good shape, you can stop adding extra Floetrol.

The Dry Time

Generally speaking, Floetrol should dry within 12 to 24 hours. However, this can be longer depending on how much you use, and the type of paint.

Also, high humidity can prolong the drying and re-coating time. When used on bare metal, though, it should dry within a day.
