Polyester resin can be thinned out using no more than 10 percent acetone. Any more and the fiberglass will not completely harden.
Can I thin resin with acetone?
Method #2: Thinning Epoxy Resin Using a Solvent Solvents like denatured alcohol, lacquer thinners and acetone. All of these solvents are easily available and also do a great job in lowering the viscosity. Also, these solvents evaporate quickly and are unlikely to become trapped in your cured epoxy resin.
How do you make resin thinner?
The general rule of thumb is to mix in thinner at a ratio of 10 to one. So, if you have 10 gallons of epoxy resin, then thin it using one gallon of paint thinner or acetone.
What breaks down fiberglass resin?
Heat the fiberglass with a heat gun, blow torch or iron. Place the heat source close to the fiberglass and move it slowly across the surface. This heats the resin beneath the fiberglass. It breaks down, allowing the fiberglass to be stripped.
Can acetone be used to thin gelcoat?
One of the most commonly used products for thinning gelcoat is acetone, and though this product will lower the viscosity, it has a strong tendency to adjust the color of the material as it cures.
How do you thin epoxy resin with acetone?
When using acetone or paint thinner for thinning epoxy, the general rule of thumb is a maximum of 10% added to the epoxy resin. An example would be if you had 32 ounces of epoxy that you were mixing you would only add up to 3.2 ounces of acetone to that mixture. Recommend over acetone and other solvents.
Can you use acetone on epoxy resin?
Acetone is another simple but effective way to remove resin. Similar to vinegar, acetone is found in almost every household. Put some of it on a cotton swab and rub the affected area until the epoxy resin can be removed.
How do you make epoxy resin runny?
Thinning epoxy using heat You can heat the resin and hardener components separately and then mix them together to create a thinned epoxy. Or you can heat the substrate – such as wood – and apply your room temperature resin and hardener mix to the heated surface.
Why is my resin too thin?
Sticky resin is typically caused by inaccurate measuring or under mixing. The three most common sticky issues are: Liquid, runny resin: causes can include not following the correct 1:1 ratio of resin and hardener, or by adding too much colorant. The liquid resin will need to be scraped off before you pour a fresh coat.
Does acetone dissolve fiberglass?
Fiberglass surfaces, like other surfaces, are susceptible to stains. Acetone removes not only dirt and grime from your fiberglass surfaces, but also any set-in stains like rust and pen marks.
Can fiberglass be dissolved?
Dissolving fiberglass involves dissolving the resins and binding agents and not the glass particles themselves. Once the resin and other binding agents are dissolved the fiberglass itself fails. Sand the surface of your fiberglass to remove any protective gel coating.
Does vinegar dissolve fiberglass?
Does vinegar dissolve fiberglass? Vinegar is a safe alternative to harmful chemicals. The best way to remove fiberglass fibers is by first taking a hot shower first, then rinsing off the area with vinegar.
How do you make gelcoat thinner?
Gelcoat may be thinned for use in a Portable Preval Sprayer with styrene monomer. You can spray it with a polyvinyl alcohol (PVA) before gelcoat reaches its gel stage (5-10 min.), or adding 1oz per quart of a wax additive sanding aid.
What do you use to thin out gelcoat?
Thin gel coat to your preferred viscosity using #70 Styrene Thinner or #1039 Duratec Clear Hi-Gloss Gel Coat Additive. When using styrene thinner, add to gel coat at 2-5% to lower viscosity and aid in spraying.
What is brushable gelcoat?
Brushable Gelcoat is a unique high quality product with excellent leveling characteristics, allowing application by paintbrush or roller without leaving brush marks or streaking and eliminates the need of spray equipment. Excessive brushing may cause pinholes and streaks.
