This is a superior exterior coating formulated to produce a high quality, flexible finish to withstand water and weather. It also contains ultraviolet absorbers for advanced sun protection. Available in satin, semi-gloss and gloss sheens.

Directions

Where to Use
Spar-Marine Varnish is recommended for use on exterior wood, fiberglass, coated metal, or painted surfaces. It can be used on unfinished wood surfaces or previously finished surfaces. This finish can also be used over stained surfaces that have thoroughly dried.

Ideal for use on exterior surfaces, such as fences, railings, lawn furniture, doors, boats, and marine surfaces. For interior use on windowsills and door frames for added ultraviolet protection. DO NOT USE on wooden decks or steps, wood siding, log homes, or wood boats below the water line.

Surface Preparation
All surfaces must be clean, dry, and free from dirt, wax, grease, glue, and other contaminants or penetration and adhesion will be affected.

Bare Wood: Sand surface thoroughly with medium grit sandpaper and progress to fine grit sandpaper. Always sand in the direction of the wood grain. Remove dust with a tack rag.

Previously Finished Surfaces: Surface should be sanded to remove imperfections and gloss, using extra fine sandpaper (220 grit) and, sanding with the grain. Remove dust with a tack rag.

Stained Surfaces: Stain must be thoroughly dry before applying clear finish. Do not sand uncoated stained surface.

Note: If a sealer is desired, we recommend Old Masters Penetrating Sealer.

Application
Stir thoroughly before and during application. DO NOT SHAKE. Do not apply in direct sunlight or areas of extreme air movement.

  • Apply with pure bristle or polyester brush, flat pad, or spray.
  • Apply in full, even coats. Flow on with minimum brushing to achieve a glass-like finish.
  • Spar-Marine Varnish will dry to touch in 4 to 6 hours. Under ideal drying conditions, allow 8 to 16 hours before recoating. Overnight drying is recommended.
  • Sand lightly between coats with fine sandpaper (220 grit) to produce a finer finish and promote adhesion. If sandpaper gums up, allow more dry time. Remove sanding dust.
  • Reapply. For exterior surfaces, a minimum of three coats should be applied.

Maintenance
As with all exterior clear finishes, this product will not offer unlimited protection against the elements. Surfaces which receive direct sunlight may have to be re-coated annually to maintain gloss and to prevent cracking and peeling.

Thinning
Do not thin. Use as packaged.

Coverage
Approximately 500 square feet per gallon. Coverage will vary significantly depending on application method and condition of wood.

Drying Time
Apply when air and surface temperatures are between 60° and 90°F and humidity is between 30% and 70%. At 50% relative humidity and 70°F, Spar-Marine Varnish will dry to touch in 6 to 8 hours. Under ideal drying conditions, allow 8 to 16 hours before recoating. Overnight drying is recommended. Drying time will be affected by temperature, humidity, and film thickness. Protect product from freezing prior to and during application.

Wait 24 hours before subjecting surfaces to light use. Care should be used during the first week after application as the finish is curing to its ultimate hardness.

Cleanup
Using a cleaning solvent, such as paint thinner or mineral spirits, is recommended for cleanup.  The use of paint thinners or mineral spirits may violate VOC compliancy in your area. Check with your local government agencies to ensure proper compliancy.

Why use clear finishes?

Clear finishes are used to seal and protect surfaces. In many cases, clear finishes offer lasting, durable protection from abrasion, marring, and chipping. Most clear finishes also protect the surfaces from damage caused by water and alcohol. Exterior clear finishes provide protection to withstand water, weather, and sunlight.

Clean Look, Sturdy — can’t ask for more!
Size: 6 Panel-119"W, Color: Grey, Size: 6 Panel-119"W, Color: Grey
Really like how it folds so I can create kind of a doorway with two of these. Pretty easy to assemble and has an uncluttered clean look due to the smooth fabric and nice color. Oh and it’s sturdy enough for pets.

Easy peasy
Size: 1 Panel, Color: Black
Bought this single-panel room divider for my son so he has a little privacy when he has to keep his camera on for online classes. It’s lightweight, easy to set up, and does the job—he can focus without me photobombing in the background. He can feel like he has his own tiny corner office, even if it’s just the basement.

Great product, sturdy and well made. Easy assembly.
Size: 3 Panel, Color: Beige
These are awesome! They were easy to assemble. They are lightweight and easy to move. I was able to easily put all 6 pieces -(I ordered two sets)-into the back of my SUV at once, by myself (and I'm a short, older lady). Quality material. Very sturdy and steady. The first set I opened was a used one and did not include instructions, but it was still very easy to assemble and figure out. I recommend using a battery powered screwdriver. With that, the assembly of all 6 panels took less than 45 minutes.
