5 Tips on how to use Brushable Gelcoat

Brushable gel

Brushable Gelcoat is a specially formulated product that is made to be applied like paint and eliminate the need for spray equipment. It has excellent leveling, Water/Osmosis resistance, UV light Stability, great Gloss Retention and a fantastic long-term durability. It comes in many different colors and can be bought online or in our stores! So, let’s talk about some tips on how to get the most out of the Brushable Gelcoat.

  1. Don’t add Patch Booster or Sanding Aid! You heard that right, you don’t need to add sanding aid to Brushable gelcoat to have it dry tack free! The self-leveling technology added doesn’t require any additional products or additives.
  2. Proper gelcoat application requires you apply your coats about 15-20 mils thick,

    using a mil gauge.

  3. Allow the gelcoat to cure overnight and then lightly sand it and buff it for an outstanding shine!
  4. Use Acetone for your cleanup. Just like other Polyester-based products, Acetone is the best cleanup material!
  5. The most important step: Adding the proper amount of Catalyst. We recommend 1.5%-2% Catalyst ratio. After adding the catalyst, you will want to mix for two minutes, preferably with a mechanical agitator (drill mixer). For your reference, here is the catalyst chart so you know exactly how much catalyst you need.

BONUS TIP: In the hot Florida weather, working time is tough for any gelcoat. So our FGCI Pro Tip is to chill the gelcoat down to 70 degrees before mixing. This way you can get a bit longer working time.

8 Solvents for Cleaning Up your next Job

solventA major part of our business here at FGCI is dedicated to solvents. Solvents are used for many things, but especially for cleanup. When you finish a project, you want to be able to clean up your mess, right? Everything from cleaning spray guns and brushes to wiping down the project afterwards, solvents are an important part of your project process. When you start a project, you want to make sure you pick up something to clean up, but which one works best? Let’s look!

Acetone

Acetone is a necessity for cleaning up polyester resins and gelcoats. Acetone is also a very important step in treating your part before spraying gelcoat, as it helps get any and all oils off the part to avoid blemishes. This is probably the best overall cleaner.

Lacquer Thinner

Lacquer Thinner is a must for removing oils. You will see a lot of mechanics use this for parts cleaning and washing as it is great for removing a lot of the grease left by engines. You will also see this product offered in different degrees of purity, from the wash-grade to the medium to the high-grade.

Isopropyl Alcohol

Our Isopropyl Alcohol is 99% water free. This product is great for cleaning epoxy, especially for wiping down a new epoxy bar-top.

Mineral Spirits

Mineral Spirits are a tried and true paint cleaner you will see used by anyone painting a polyurethane or enamel paint as it breaks down the paint very quickly.

Styrene

Styrene is a common solution found in resins and gelcoats, sometimes called ‘wax.’ Styrene is commonly used to thin down resin to allow it to seep into wood easier. We don’t recommend using it to thin gelcoat, however.

Toluene

Toluene is a great multi-use product as it’s great for cleaning epoxy, but it also works for cleaning paint as well. Toluene is mainly used for cleaning up silicone and it does a great job on 5200.

T-12

T-12 is a very volatile solvent used mainly for cleaning epoxies. This solvent dries extremely quickly, but you will see it used frequently for cleaning brushes between uses.

Xylene

Xylene is used mainly as a thinner for enamels. It can also be used for cleanup for paints as well.

The most important thing to remember with all of these solvents is that they all require proper protection. Gloves and some sort of clothing protection would be the least you can do. You may also consider respirators and eye protection as well. You also want to remember that all of this material is flammable, so be cautious and store it properly.
