Removing the erstwhile window sills
Okay, this is where it's more than than a piffling cringey and I'm totally embarrassed for you to meet just how bad we permit one of our wooden window sills go. (This is by far the worst ane, from the now-actual office that just recently became formerly known as the dog room … simply just gotta rip information technology off like a bandaid.
You can see the common issues – peeling pigment from moisture, dings and scratches from our security team's nails…
Beginning, we removed the former wooden sill to use as a template to make the job every bit piece of cake as possible. (You could measure out and cut the marble without a template, merely if your sills are like ours, you'll find zippo is truly square, even if information technology looks like it.)
Using a box utility pocketknife, nosotros advisedly scored the caulk around the wooden sill where it met the wall and moulding underneath it. Then using a flat head screwdriver, hammer and firm putty pocketknife, nosotros gently pried up and rocked the sill until it was loose. We removed the nails in the wood with needle nose pliers, and vacuumed and deeply cleaned the drywall ledge and window frame area for debris, dust and loose drywall. The cleaner the ledge, the better the marble will stick subsequently.
Nosotros labeled each sill as nosotros removed them, which helped keep things really like shooting fish in a barrel later.
Templating the marble
Offset, we made sure to effigy out which side is front border of the marble sill. Our pre-fab sill pieces of marble have dissimilar edges – a slight, polished bevel on the long front edge, and a straight cut with a rougher-looking appearance that sits nice and tight confronting the back/window-side. (You can fifty-fifty run into in the first photo beneath the lesser cut edge of the marble looks a little chippy and rough; that's the dorsum that will be installed touching the window.)
With the old sill upside downwardly on top of the new sill that was also upside down, nosotros marked out sill shape/length on back of marble with Sharpie, making certain to line up the back, window-side role of the old sill to the back of the new sill. Our new sills are deeper (at six") than the sometime sills (at 5.25"), and considering the existing window frame depth won't change and nosotros take no intent to cut our new sills length-wise to make them shallower, our new sills have deeper front/side wraps/tabs than the former sills had (past .75").
Just to make it extra clear, we marked the fleck piece to be cutting out and removed with an "X".
Cutting the new sills
Making sure our marble sills were well supported through the middle to avoid any sagging or stress as we cut, we used our four.5" circular saw and a water hose on a very low stream to keep the blade and marble cool and wet as we cut the marble (bottom side facing upwards) on the lines previously marked out.
Taping off the cuts: what y'all don't need to exercise to get a clean cut.
Tips for getting make clean marble cuts
At first we tried cut on/through painters tape, but it just kind of lost its stick in the water and got caught up in the saw, and didn't add anything in terms of keeping the cuts cleaner or the marble from breaking.
Nosotros learned the marble had a tendency to accident out a piddling on the end of the cut when exiting the marble whenever it got thin plenty. Because of this, when cutting the marble to total length earlier cut the notches, we cut from the finished front end border through to the back, window-side of the marble so information technology would blow out in the fleck area.
Considering we're using a round blade to cut a directly inside corner cut, if we didn't go slightly past our template line intersection (on just the back - the round blade ways it's where it needs to be on what will be the top side of the sill), or if the piece broke off before we got that close, we sometimes had a pocket-size burr left in the corner when the small marble corner slice came costless.
We used the Dremel and a lilliputian rotary accessory (dry) to gently clean up the inner corner burr as well as on an angle to soften upward the freshly-cut marble edges. Before install, we wiped down the marble with a dry rag, dry fit the marble on the window ledge and used the Dremel to brand any slight adjustments needed to brand the marble fit tightly, but easily.
Installing the marble
We used a fair corporeality of marble construction adhesive to advisedly mucilage down the marble onto the window ledge. And so nosotros practical some adept force per unit area to the top of the marble past hand to get good contact. The weight of the marble itself kept information technology in place, and nosotros kept the dogs off of the sills while the agglutinative dried.
Finishing the expect
We used paintable caulk to make full the gaps in the drywall and where marble met with the wall and the piece of decorative "support" moulding we have underneath each sill. Don't worry if yous notice a larger than ideal space in the drywall.
The gap in the photos beneath was by far the worst, and as nosotros establish out when we were cleaning up the window frames the metallic corner support, spray texture, "drywall" and "wooden" window sill were non-existent and it was all just filled with caulk!
Since we didn't have a dorsum gap to fill and weren't going to paint it, nosotros used a very minor corporeality of clear silicone in the seam where the marble meets the actual metal window frame. It's so thin and clear it's practically invisible, as you tin can barely see in the photos below where the black window meets the marble. The white caulk nosotros used to fill the larger gaps effectually the wall stands out far too much against the softer, gray-white of the Carrara marble, specially at present that we have blackness windows, and we want the beautiful natural marble to be the star of the bear witness.
One time the caulk stale, we put down some painters record to get a clean edge and touched upward the wall pigment color.
Before + later on
My favorite part – seeing the side-past-side transformation!
I just love the manner our trees reflect in the glossy marble...
And how no two patterns in our natural marble sills are exactly alike.
What do you think? Is this await a hit or miss?
