The Best Exterior Wood Finishes

  Inside our homes we’re surrounded by wood furniture, cabinets, millwork, and other wood items with beautiful finishes… and without much thought we simply expect them to last a lifetime. The finished wood items we have outside aren’t so lucky.  They’re exposed to the extremes of solar radiation from the sun… moisture in the forms of dew, rain, and snow…. high temperatures… freezing cold… fungal attacks... and in some cases foot traffic.  Good exterior finishes protect the wood from these harsh [...]

2K Catalyzed Polyurethane Finishes

How to Measure finish Viscosity

How to Measure and Adjust the Viscosity of Spray Finishes

  With one simple tool you can easily measure and adjust the thickness of your finish to make sure it will spray well.

Old paint cracks and peels

Why Finishes Crack & How to Fix It

    Cracks are one of the many ways that coatings (film forming transparent finishes and paints) can fail.  They occur in a variety of forms to include checking, crazing, cracking, alligatoring, and mud cracking. All of these forms are the result of stress. Checking is a mild form of cracking and doesn’t go all the way through the finish. It often forms irregular, non-linear patterns called ‘crows feet.’  Crazing is similar to checking though the breaks are deeper and wider.  As [...]
