Scrape the loose glazing compound away from the wooden sash using a stiff putty knife. The steps found at house painting santa monica pluck and feather lists them in order for anyone managing a repaint project in Santa Monica, CA. Removing old material is the first stage of maintaining window integrity. Dust and residue must be cleared from the channel before any new compound touches the wood.

Mechanical Removal of Old Glazing

Old putty often becomes brittle or separates from the frame. A sharp chisel or a specialized glazing knife works best to lift the dried material. Excessive force can splinter the wood grain. Small fragments of glass can remain stuck in the frame. These shards require careful extraction. Removing every trace of the old oil based compound prevents the new material from failing prematurely. Sanding the wood after removal ensures a flat surface for the next layer.

Preparing the Wood Surface

Clean the bare wood with a lint free cloth. Any oils or dirt left behind will prevent adhesion. Applying a high quality primer is necessary to seal the grain. This step prevents the wood from sucking the moisture out of the new glazing compound. In the coastal climate of Santa Monica, CA, moisture management is a priority. A single coat of primer creates a stable base. If the wood shows signs of rot, patching with a wood filler becomes a requirement before moving forward.

Applying New Glazing Compounds

Press the new compound firmly into the glazing bead. Smooth the surface with a putty knife to create a clean, slanted edge. This shape allows water to shed away from the glass. The compound must be applied in a continuous bead. For large areas, work in sections to prevent the material from skinning over. A smooth finish reduces the amount of sanding required later. Achieving the correct profile prevents water from pooling against the glass pane.

Finishing and Coating the Windows

Wait for the compound to reach the correct hardness before applying paint. Applying paint too early causes the compound to slump. Once dry, the edge needs a light scuff sand to remove any imperfections. The first layer of paint should be an oil based product to ensure maximum adhesion to the glazing. Once that layer is set, a topcoat of acrylic paint provides the final weather resistance. A satin sheen is often preferred for exterior trim to balance durability and aesthetics. Two coats provide the necessary coverage to protect the wood from the elements. The mil thickness of the final film determines how long the finish lasts against salt air and sun.
