Preserve Your Finishes with StopLossBags
StopLossBags are a practical innovation for woodworkers, designed to store and preserve oil-based and solvent-based finishes without exposure to air. Traditional metal cans and bottles allow oxygen to degrade finishes over time, leading to skinning, thickening, or complete spoilage. StopLossBags eliminate this issue with an airtight, collapsible design that ensures minimal air contact, even after repeated use.
Each StopLossBag holds up to 1 litre of finish and features a UV-resistant, multilayer construction with a secure screw cap. As you dispense the liquid, the bag collapses—automatically displacing air and protecting the contents. This makes them ideal for storing products like polyurethane, tung oil, shellac, Danish oil, linseed oil, and varnish.
For woodworkers who use high-quality finishing products in small quantities, StopLossBags offer a cost-effective and environmentally friendly alternative to throwing out half-used tins of spoiled finish. They're also excellent for decanting larger tins into manageable portions, perfect for bench work or mobile setups.
With available funnels, labels, and colour-coded caps, the StopLossBag system keeps your workshop tidy, your finishes fresh, and your projects on track. It’s an essential storage solution for anyone who values the longevity and performance of their wood finishing products.
FAQs
What is a StopLossBag used for?
StopLossBags are used to store finishes such as oils, varnishes, stains, and shellac while preventing them from coming into contact with air. This preserves the finish and prevents skinning or thickening over time.
How does a StopLossBag work?
The bag collapses as the liquid is dispensed, which prevents air from entering the container. This eliminates oxidation and keeps the finish fresh for months or even years, depending on the product.
Can I reuse a StopLossBag?
Yes. The bags are reusable. After using the contents, you can clean the bag with the appropriate solvent and reuse it for the same or a different type of finish.
What finishes are compatible with StopLossBags?
They are compatible with most oil-based and solvent-based finishes, including tung oil, Danish oil, polyurethane, linseed oil, shellac, and oil-based varnishes. Water-based products are not recommended for use with these bags.
How long do finishes last in a StopLossBag?
When properly sealed, finishes stored in a StopLossBag can remain usable for significantly longer than in traditional cans—often up to several years, depending on the product and storage conditions.
Are the bags safe for long-term storage?
Yes. StopLossBags are made from chemically resistant, UV-stabilised multilayer film that is safe for long-term storage of oil-based and solvent-based finishes. Just be sure to store them away from direct sunlight and heat sources.
Can I label the bags?
Yes. Each bag has a writable surface or you can use the included labels to clearly mark the contents, date, and other details. Colour-coded caps can also help differentiate multiple finishes in your workshop.
How do I clean a StopLossBag?
Cleaning depends on the finish used. You can rinse the bag with the same solvent that thins the finish (e.g. mineral turpentine, alcohol). Rinse thoroughly, allow to dry, and it's ready for reuse.
