Step 7: Cut in Around Moldings

Cutting in
Photography by Kolin Smith
«»
At doors and windows, let the paper overlap the molding by at least an inch.

Using the razor, make a relief cut in the paper. Carefully run the razor from the molding corner out to the edge of the paper. Use the molding as a guide.

Press the cut edge tight in the joint between the molding and the wall.

Trim the excess paper flap with a taping knife and razor, ABOVE. Smooth down the whole sheet.

Tip: Hide small cutting errors on darker papers by coloring the wall or the white edge of the paper with a marker that matches the paper. Some pros even color all the paper's edges so seams are not as evident should the paper shrink as it dries.

    Shopping List

    1. WALLPAPER

    Check the size of the rolls before calculating how much you need. Wallpaper is often priced by the single roll, but can be bought as a continuous double roll. Depending on the size of the pattern's repeat and the width of the rol, a double roll will cover anywhere from 36 to 50 square feet. Many paper companies and retail shops will calculate how much paper you'll need if you provide the square footage of your walls (subtract for windows and doors). Or you can use the wallpaper calculator in the Helpful Info section below.



    2. PREMIXED CLEAR WALLPAPER PASTE

    Paint that's not mixed correctly can ruin a wallpaper job. So for most papers, it's better to buy premixed products. One gallon is enough for 5 rolls.



    3. WALL PRIMER/SIZER

    such as R-35 by Roman Adhesives. These products make the wall feel tacky but actually extend the working time of wallpaper paste and make manipulating the paper easier. You'll need 1 gallon per 100 square feet.



    4. PAINTER'S TAPE

    or masking tape. For holding wallpaper onto switch plates and receptacle covers while the paste dries. One small roll is all you'll need.
