Enamels have high viscosity, which makes application quite difficult. Use a good quality thinner to thin the enamel for easy application using a paint brush. The Pettit General Purpose 120 Brushing Thinner is an ideal choice for use with Pettit, Z Spar and Shipendec solvent-based topside enamels and varnishes.

This antifouling thinner has a moderate evaporation rate, allowing you to paint at your own pace. For best results, mix 10% thinner with enamel.

  • Effectively thins enamel for easy application
  • Mix 10% thinner with enamel
  • Moderate evaporation rate

  • Capacity: Quart

Pettit 120 Brushing Thinner is a general purpose thinner for thinning brushing enamels for easier application. Many paints when stored for some time before use will increase in viscosity and should be thinned with a good thinner for normal brush application. The 120 Brushing Thinner evaporates at a moderate rate and is completely out of the paint film in several hours. Surfaces can also be washed with this thinner prior to preparation or painting to remove any contamination or sanding residue.

Add up to 10% of the thinner to any of Pettit's Enamels, Easypoxy, standard undercoaters and primers, and varnishes. Mix in thoroughly.

Pettit manufactures a wide array of thinners to compliment our various coating products. The Thinners are matched to the product, method of application and atmospheric conditions present at the time of application. When application temperatures are high (80°F and above) slow thinners are recommended to improve brushability and flow of the product. Generally, faster evaporating thinners are utilized for spray work to maximize atomization while mini mizing the chances for runs and sags. Faster evaporting thinners are also useful for brush and roller work at lower temperatures (60°F and below) since there is less chance of these thinners becoming trapped under the drying paint film causing blistering at a later date.

Never overthin a varnish, enamel, undercoat, primer or other paint product. Doing so could lead to reduced gloss upon drying or a reduction in the performance of a product. Always follow the thinning instructions given on the label or technical data sheet for the specific product being applied.

by Greg from North Port, Florida on September 13, 2016
Product seemed to work better than standard Home Depot thinner. As always, customer service was outstanding. iBoats is my first choice for paint products as shipping is overnight.
