1. Cut the sheet vinyl using the techniques described for Perimeter-bond Sheet Vinyl (steps 1 to 5), then lay the sheet vinyl into position, sliding the edges underneath door casings.

2. Pull back half of the flooring, then apply a layer of flooring adhesive over the underlayment or old flooring, using a 1/4" notched trowel. Lay the flooring back onto the adhesive.

3. Roll the floor with a floor roller, moving toward the edges of the sheet. The roller creates a stronger bond and eliminates air bubbles. Fold over the unbonded section of flooring, apply adhesive, then lay and roll the flooring. Wipe up any adhesive that oozes up around the edges of the vinyl, using a damp rag.

4. Measure and cut metal threshold bars to fit across doorways, then position each bar over the edge of the vinyl flooring and nail it in place.
