  4. Q I have have a new storm window that used type m on, now it has been 3 weeks and I have a few spots where the glazing is still soft and bubbly. I did not prime the window rabbit, I did apply BLO and mineral spirits 50/50 mix. all other window are good.
    Answered by the admin You should always prime prior to using the glazing compound.
  5. Q Storage of my container of Type M has failed. When new it started as extremely sticky and was almost impossible to spread; it stuck to my hands and tools like it was thick paint. I had to wait for a week or two before trying again and things went much better. I finished four windows and set aside the pail after putting a sheet of Sarah wrap on the putty before closing the lid. Three months later I needed to glaze another window but the putty was very dry and not usable. I had to throw away the top couple of inches in the pail and dig out some softer putty at the bottom to finish the job. What caused the drying?
    Answered by the admin

    The oil sinks to the bottom during long periods of storage. To prevent those types of issues you could store the tubs upside down, which would keep the oil at the top in between uses.

    So far, this stuff is horrible. It’s extremely sticky and nearly to impossible to use. Cleanup of tools and my hands was very difficult. I would accept the stickiness if the instructions mentioned this possibility and what to do about it. The problem is there are no instructions. The side of the tub has only one sentence about allowing it to skim over before painting and that’s it. It’s possible that detailed instructions that cover common problems are available somewhere but, after searching the internet, I haven’t found it. I have found conflicting advice, however. This product should at least come with much more detailed instructions, rather than appearing to cater only to those who have been glazing windows for 30 years. I bought it because the DAP glazing compound is so maligned on the internet. I can’t imagine anything being worse than the Sarco putty.
