Gather your supplies and might want to put paper(cloth) down to protect surfaces.
The chalk line used in this guide. Find where you want to start. I decided to start in a square corner. The tiles are 24" wide. I measured from the wall out 24", made a mark and did this down the wall
Take the chalk line and stretch it from the first mark to the last, to see if any marks are outside the chalk line. If there is, find out what distance off the line and move chalk line out that much.
Now snap your chalk line to get a straight edge. This is where to align the tiles. I rolled the contact cement on the ceiling, a little bigger than the tile. Now wait about 15min to dry.
Now roll the contact cement onto the tiles and again wait about 15mins to dry.
Might as well get the row of tiles done so install can go faster.
Now line up one edge to the chalk line as close to the wall as possible. Make sure you are careful because once contact is made they stick. Start at the chalk line and press tile onto the ceiling.
Take the rest and start installing trying to stay as straight as possible on the chalk line. Once the first row is up now start the second. Roll contact cement on ceiling and tiles, wait 15mins.
At the end measure how much tile to cut and use the scissors to cut tile. Cement, wait, and install. To finish it off add some trim around the ceiling to hide gaps.
All done and it looks pretty good!! I'll finish the trim later once I figure out what type to use.
