Dual Glazing Compound

Sarco Dual Glaze Elastic Glazing Compound 

Use on site or in the shop on wood or metal

This glazing compound holds a permanent, water-tight bond on wood and metal sash and doors. Easy to handle, it is made with non-drying linseed oil that sets into a firm, tough cushion and adheres tightly to glass and sash. Dual glaze allows for normal expansion and contraction without pulling away. Ready for oil or latex paint after surface skin has formed, usually in 2-3 weeks. It is the most versatile glazing compound for glaziers, painters, and homeowners.

Customer Questions & Answers

  1. Q I am in the midst of restoring 96 year old windows. Live in Iowa. I have seen information on the Internet that Sarco Dual Glaze compound should not be allowed to cure inside. The warmer the temperature Sarco states in a PDF FAQ the faster it will set up and the skin will develop. Also Dual Glaze should not be applied when the temperature is 20 degrees and below. I want to move this project along and not wait until late spring and summer to complete this project. So what is actual fact. Can you apply Dual Glaze to the exterior side of a window inside a house where the temperature is between 65-70 degrees depending on the time of the day.
    Answered by the admin

    Dual Glaze can be applied indoors (see FAQs).   At 60 °F the product should skin over nicely.

  2. Q Is it necessary to paint the dual-glaze? Or can it be left to skin over and cure unpainted? Is there another glazing compound that does not need to be painted?
    Answered by the admin

    According to Sarco (the product manufacturer), it should really be painted after skin formation.  Otherwise the product will lead to failure with cracks in the surface and degradation of the product itself. 

  3. Q Hi I'm embarking on a an exterior metal window project in January the dead of winter and need a good quality glazing compound/ putty .. sarco ???
    Answered by the admin

    Dual Glaze is best applied above freezing.  It can be applied below freezing as long as it can be worked. 

  4. Q I live in Los Angeles. Do you know if there are any of these in stores near me?
    Answered by the admin

    Unfortunately, I don't believe there are any that stock the glazing products in your area. We do however, sell them online or via phone and can do expedited shipping if necessary. 

  5. Q Will putty freeze? Can I glaze if temps go below freezing at night?
    Answered by the admin

    The cold weather doesn't harm the putty, but it will take an exceedingly long time to skin over at freezing temperatures.
