Frequently Asked Questions

Can Brushing Thinner 100 be used with all TotalBoat products?

TotalBoat Special Brushing Thinner 100 is not for use with all TotalBoat products. It is formulated especially for use with TotalBoat Wet Edge topside paint, TotalGold, TotalTread non-skid paint, and others. Do not use this thinner with JD Select, Aluminum Boat Topside Paint, Envy 2-Part Varnish, Inflatable Boat Paint, 2-Part Epoxy Primers, TotalProtect, or Aluminum Boat Barrier Coat.

For more information on product compatibility, refer to the technical data sheet.

What is the difference between Brushing Thinner 100 and Acetone?

TotalBoat Brushing Thinner 100 solvent contains high flash naphtha, not acetone.

Can Brushing Thinner 100 be used with one part paints from other manufacturers?

In general, yes. Although Special Brushing Thinner 100 was originally formulated to improve the flow of Wet Edge topside paint, TotalTread Non-Skid paint, 1-part varnishes, and others, it may also be used with other 1-part polyurethane finishes.

Is this solvent intended only for use in warm weather?

No. Thinner 100 is the recommended brushing thinner for paints like Wet Edge, even in cooler conditions.

How much Thinner 100 should be used for varnishing in warm weather?

Thin the first coat of TotalBoat Gleam or Lust varnish 50% with Thinner 100. For a high gloss, thin later coats no more than 8 to 10%. You may even thin the final coat as little as 5%.

What is the right way to add this solvent to the paint or varnish you are using it with?

Add TotalBoat Special Brushing Thinner 100 slowly and carefully to the paint or varnish to avoid spillage. Then, mix it thoroughly until the desired viscosity is reached.

Why would you need to use this thinner when painting, priming, or varnishing?

Using Thinner 100 will create a smoother flow, making it easier to apply paint, primer, or varnish. Due to its slower drying properties, Thinner 100 extends the working time in warm weather conditions.
