Bathroom Mini Heki
Why do this? To make the bathroom lighter and brighter and to make the rooflight easier to use. A Mini Heki is much easier to open/close and use the flyscreen/blind.
Problem? The existing rooflight is 360mm x 320mm, Mini Hekis are 400mm x 400mm.
Solution? The roof opening will have to be enlarged to fit.
|
1st job is to read the instructions, well they are just pictures. Ceiling is 31mm thick, that means later on the lugs on the surround will have to be cut to 6mm and use the 25mm screws to secure.
|
Standard 400mm x 400mm with permanent ventilation (this is the correct one for a caravan).
|
This is the rooflight that is going to be replaced, it does not allow much light in and is quite hard to open.
|
|
This is what it looks like inside the toilet compartment before work commences.
|
Flyscreen removed, the eight screws securing the internal trim are removed next.
|
A tug and it comes away.
|
|
The work to remove the rooflight is now from above.
|
Score the mastic with a blade, being careful not to mark the roof finish. Concentrate on lifting one corner.
|
Here using a screwdriver to stop the corner from re-sticking itself, allowing the mastic to be cut through.
|
|
Then it comes away. The mastic is in good condition as it was resealed 42 months earlier.
|
Now for the clean up. The tools/chemicals needed to remove the existing mastic.
|
Using a plastic scraper to help remove the bulk of the mastic.
|
|
Most of the mastic removed, be patient.
|
The use of white spirit and paper towel to remove what's left.
|
Any stubborn bits need a little more rubbing.
|
|
Referring to the instructions, masking tape is used to show where the roof will have to be cut back to. I am just going to extend the opening.
|
Marking out, a pin punch is used to mark 6mm in from the corners.
|
A pilot hole is then drilled in the 3 corners and checked inside where they appeared.
|
|
Now a 12mm drill is used to drill down just over half way. Masking tape was used as a guide.
|
Then from below drilling up.
|
A jigsaw, the base covered with masking tape to protect the roof surface from scratching, is used to cut from corner to corner.
|
|
This is the "L" shaped piece that was cut away - scarey!
|
This is what it looks like looking to the rear.
|
And this is looking to the front.
