I have a 1930s home with original windows and need to re-caulk around the exterior as its getting worn out. I assume I need to remove all the old caulk? I have a couple pictures below, but there is brick next to the window.
Are there any tips to remove this old caulk and clean to apply new caulk? The old is hard and will be hard to remove. I assume I have to remove before going over, correct?
One of my favorites is a painter's tool, then there is a old screwdriver and putty knife. There aren't too many secrets to removing old caulk other than sweating and digging the old out. You'll just have to see once you get started. Yours is cracked and separated from the brick so it looks like the wood side will be the difficult part. Sometimes a wood chisel can be slid down the border between the wood and caulk to cut or pop the old caulk off.
I have good luck removing old caulk by using an oscillating tool with a worn blade. The tool does most of the work as you move up, and you don't worry about hitting brick because the blade is already smooth.
You may want to use oil-based caulk when you re-seal. Oil based caulk will stand up best to heat and flex.
I replaced an old window and had to make the window frame smaller. I decreased the frame by 1” on each long side and about 2.25” only one short side on the bottom. Trying to figure out the best way to trim it out inside and outside.
Inside: Cut a very slim piece of drywall to cover the newly added frame, install trim, patch wall, and repaint? Maybe use plywood instead of drywall?
Outside: take trim off, cover the new frame with slim of plywood, replace trim, paint?
any better/easier solutions?
i’ll upload pictures from my PC tomorrow. Thanks for suggestions!Read More
Hi all,
my first post here, I was inspired by interesting threads like [url=https://www.doityourself.com/forum/doors-skylights-windows/558621-velux-vse-electric-skylight-repair.html]this[/url] (closed) where a replacement of a transformer for older Velux model is discussed.
I am considering replacing transformer of my Velux GGL Integra window. Transformer is broken (Type 869030-01- Model 3UCA01EU - [b]output 20VDC 1.8A[/b]) while motor is ok (Motor Model 3MG A01 WW Type 869024-01 - [b]nominal[/b] [b]input 24V DC 8W[/b]).
My idea would be to place the new transformer inside a DIN electrical box at the floor (hosting other breakers, differentials etc...) like the one [url=https://hager.com/pt/catalogo/produto/st312-transf-seguranca-230v-12-24v-25va-4m]here[/url] so that I can send to the motor in the window in the roof the 24VDC directly, instead of the 230AC (EU). It would even be safer! By using the very same cable.
I have some doubts about this setup (not tested yet):
[list=1]
[*]I can easily buy 24VDC DIN transformers (example in pic), almost impossible is to find 20 DC DIN transformers. The original Velux transformer is 20VDC, it has the "isolation transformer" symbol on it, while the original Velux motor is 24VDC .... so not sure, maybe I should send 20VDC to protect better the motor? Moreover, I read in previous threats that transformer better be not-switching, and maybe there is a "Blue cable surgery" to do in the motor as well ... I did not open the motor to inspect it yet.
[*]Velux Integra windows operate on RF with a dedicated Velux remote. It is possible that the board to receive RF from remote is on the transformer, making it impossible to replace it with a commodity one? Or even, is it possible that the motor, on the two cables taht connect it to the transformer, is also exchanging signalling to certify that the transformer is a Velux authentic one? That would blow my plan.
[/list]
Is there anyone who tried doing the same, and can share some advice?
Best regards!
