How to caulk windows the RIGHT WAY?
I'm trying to determine the best outdoor caulk(s) to use for re-sealing the perimeter of my vinyl windows and trim. It was done improperly the first time (see details below), this time I want to DO IT RIGHT!
I'm looking to re-caulk the windows and trim around the outside of my home. The home is about 6 years old and in the Los Angeles, CA area. Much of the wood trim has shrunk/warped since it was originally installed. This has caused significant gaps between the trim and window in some areas. The windows are vinyl with rough-cut wood trim (might be cedar - not sure). Outside the trim, the home is stucco.
The original builder apparently used a combination of latex and silicone caulk to seal the windows. Some windows are completely sealed with latex, others silicone, and some a combination. It appears to have been done with whatever they had on hand at the moment. and most windows were not sealed AT ALL along the top edge!? (out of sight, out of mind I guess) :eek:
Ive removed the majority of the existing caulk the latex was cracking and was pretty easily removed it simply pulled out in strips. The silicone has been more difficult it came out like sticky balls of snot. :laughing:
I have attached a few photos for reference In some cases the gaps between the wood and window are about 1/4 inch (or larger). The gap extends back about 1 inch from the outside edge.
Now, on to my questions to determine how to prep and caulk THE RIGHT WAY so I dont have to do this again in another 6 years!:
I would use the GE Max water clean up..
Backer rods of applicable diameter for your application.
I always like to prime before I caulk especially on wood. Then top coat over both caulk and wood. Keeps the caulk from shrinking from behind.
The vinyl shouldnt need any special prep other than clean and dry.
what would you recommend for the wood that has soaked-in the silicone caulk? Do you think the primer will seal right over top of that, providing a bonding surface for the new caulk? or should I attempt to scrape away some of the wood to reach a clean base to work with?
Wood wont absorb silicone.. If its wet in that area you would need to dry it well before re-caulking.
