Caulking wood windows is the process where seams or joints of windows are sealed together. The oldest and burliest form of caulking is applied to create the seams of wooden ships and boats, through driving fibrous materials to the wedge-shaped seams among planks. Caulking is easy, provided you know the techniques and things to avoid.
Oil-based Caulking Mixture Causes “Fog-up” Windows
Ensure you never apply an oil-based caulking mixture around insulating glass of wood windows. Vegetable oils in these kinds of caulking mixtures aggressively damage wood windows’ polysulfide polymers. This polysulfide cracks, degrades then triggers the wood window to fail as well as fog-up.
Paint Stick is Good for Leveling Caulk
Place your bead of caulk on wood windows, determine the width of tooling then mask it off using masking tape. Then, get a paint stick and cut off the corners of the stick in order to make it fit the width amid pieces of tape. Smooth the bead of caulk on wood window using paint stick for best results.
Wood Fibers Cause Caulks’ Adhesion Failure
Surface wood fibers of windows are damaged once exposed to intense and direct sunlight. That is why if a wood window sealant is applied to this damaged wood, it can cause premature collapse of the sealant due to the loss of adhesion. The sealant actually adheres pretty well on the surface wood fibers themselves. However, the surface fibers mislay their attachment to the mass of the wood window.
