How To Make A Window Sill

Awindow sill is the bottom piece oftrim, or the ledge at the bottom of thewindow. Information technology's both decorative and serves the purpose of roofing the framing and blocking out drafts and gaps at the window ledge.

How far should a window sill stick out from a wall? Thesill should overhang from the front edge of the wall or window frame at to the lowest degree 3/4 inch. You lot tin can get in hang over more if you'd like. Proceed in mind the sill should fit the scale of the window and reverberate the style likewise.

What style of window sill is all-time or most popular? Information technology makes most sense to add trim that fits the style of your habitation and moulding if yous have it. In my stance, modern window sills await best with squared ends. Traditional, transitional or eclectic homes can have rounded or square ends. Craftsman window trim, like ours, fits a wide variety of dwelling styles and it's actually piece of cake to add. Specially since information technology's all flat square boards and cuts.

Do I need to add an frock to my sill?  The answer is no. The trim under the window sill is called an apron and calculation that is optional. It does take a purpose though, many times and apron volition cover a gap. It besides adds a decorative impact and helps ascertain the fashion of a window.

I'll show y'all three styles of window trim today. A craftsman, i with no frock and a uncomplicated frock made with moulding. Yous'll get a lot more detail in the how to build a window sill video I made.

Supplies needed:

• 1 ten 6" or one x eight" select pino board depending on the depth of your window. 1″ x 6″ will be the most common.
• Super Finish Max Pigment Sprayer
• Extra Super Finish Max pigment container
• Paint
• Miter saw
• Jigsaw
• High TPI count jigsaw blade
• Construction adhesive – this is my favorite
• Sander
• Tape measure – this is my favorite one!
• Drop material
• Safety goggles – these fit over prescription spectacles!
• Respirator  or face mask

Step ane. Remove existing window sills.

Our dwelling had tile window sills and a few poorly made wood sills.  I tried to bit the tile off but that was an impossible task then I added my new ones right over them.

If you're removing old woods sills or trim, utilise a box cutter to break the caulking seal and and so pry them off with a mallet and chisel or a heavy duty flathead screwdriver.

Step 2. Mensurate the depth and width of each window.

If yous're working on several windows, it helps to make a list or diagram of each one. Cheque for items that volition limit the choices of calculation an apron or touch the size of your window sill like wall or tile trim that is in the way.

Step 3. Cut the window sill length with a miter saw.

What's the all-time material to brand a window sill? Always use the best quality wood, which is select course. It shouldn't have knots in it and you won't demand to do much sanding. Always cheque that it is not bowed or warped when picking out your lumber.

A miter saw gives the best and cleanest cut but y'all can too accept your local big box store cut each board to lengths you lot'll demand.

Choose the best side of the wood for the front and marker the dorsum of the lath so y'all know which window information technology was meant for. Marking which window the sill belongs to is a huge assistance when working on more than one.

Footstep 4. Cut the window sill ledge with a jigsaw.

Mensurate and mark the length of the sill that will extend beyond the window.  Example: my Craftsman style window sill extends 5" beyond the window frame.

Next, measure and marking the depth of the window sill, mine is 4 ¾". That leaves a three/4″ sill overhanging my window frame.

If your DIY window sill will accept a square terminate than y'all're fix to cutting. If information technology will have a rounded sides, and so mark the rounded edges now. Apply a cup or something rounded to trace the shape. It's pretty basic only works keen!

Use a high tooth jigsaw blade for fine cuts to cut out each side.

Meet how well each windowsill fits in it's window.  You lot may need to clean out more than of the sill area to allow the sill to lay flat or you may need to shave off a petty on the sill.  If you need to trim your wood window sill, be bourgeois and only accept a pocket-sized amount at a time.

Also, keep in mind windows and walls are often non square, especially in older homes.

Step 5. Lightly sand whatever edges or rough ends before painting.

I used my random orbital sander with 220 grit sandpaper.  Be certain to wipe everything downwards before painting to remove sawdust.

Step vi. Spray the pigment when possible.

I used my Super Finish Max paint sprayer because I wanted a perfect cease without brush strokes. I also wanted to save time painting. Especially since it'southward been about 100° outside hither in FL!

Below are my favorite tips for using a Super Finish Max paint sprayer. You'll see how I painted and go more tips in my video.

Larn more about HomeRight'due south family of products and the Super Finish Max on their Website.

• Drag the window sills on boards over a driblet material in a well ventilated surface area.  I used minor blocks of wood under my sills so the edges wouldn't pool paint and wreck the finish.
• Ever exercise a exam spray before painting.
• Pigment with deadening back and forth movement using your arms instead of your wrists to move the pigment sprayer.
• Run articulate water through the Super End Max to rinse and set it aside while you wait for the first glaze to dry.
• Once the first coat is dry to the touch, put the paint container back on, run a test spray to articulate out the water and apply a 2d coat of pigment.

Step 7. Install the sill into the window ledge.

Use construction adhesive to the window sill and place the sill in position. I added shims to the chipped off areas of my window frame for more than surface and support simply you lot shouldn't demand this. Unless, of form, you have chipped tile sills like mine…haha.

Place the sill in the window making sure it lays flat.  You lot can add a few brad nails if your widow is framed in wood.  Ours is block and concrete so the construction adhesive is all I needed.

If you're adding a window apron add together that now. Y'all can see my Simple DIY Craftsman Window Trim projection to see how I fabricated and added craftsman aprons and framed my windows.

Step 8. Fill blast holes with woods filler, caulk the residual.

 Use forest filler in the boom holes if you've added trim or used nails. Use painters caulk around the sill edges and underneath.

It's that easy. Here are the three styles of piece of cake window sills I made.

Do you lot remember what my office liked before?

I'grand going to go out on a limb and say this is a large improvement!

This is the Craftsman window ledge and trim.

Here's the other ii styles of window sills I made. The first is a simple apron under the ledge. It worked great with the tile trim. Normally, it would be as wide equally the window ledge but the tile trim stuck out and so I had to nestle it into the space available.

In hindsight, I recall I should have cut the sill ledge a little shorter.

I recollect it turned out well though. and much better than what was at that place, which was nothing but loose tile.

The other homemade window ledge I congenital has no frock at all. The bathroom has tile all around the wall and the fashion it sits, I idea it would look better just plain.

OK, and so at present that I've shown you how to make a window sill are yous set to tackle your own?
