XPS Backer Board Fixing Kit – Screws, Washers & Sealing Tape

Overview

Every failed wet-room schedule has the same 4 pm moment. The box of washers runs dry. The tape got left at the depot. Someone drives to the hardware store for drywall screws because they are “close enough.” They are not close enough, and the fix is not discipline. It is arithmetic. Count the fixings before the job starts, put them in one carton, and the problem stops existing.
That is what this kit is: the whole fixing layer of the board system, counted against your order, in one carton. Self-tapping screws and stainless washers for the 300 mm field grid. Anchors for masonry and concrete backgrounds. Elastic sealing tape and self-adhesive mesh fabric for every joint. Tell us your sheet count and stud layout when you order, and the carton arrives matched to the wall, not to a round number from a catalogue. Plan on one kit per ten sheets at standard spacing.
Working with thick panels? Add the textured fixing pins. They are made for the one job screws do badly: joining two boards at right angles. The coarse thread bites into the board edge and compresses the foam around itself as it drives, so the grip comes from friction over a wide surface instead of a thread hanging on by its fingertips. On a 20 mm stack or thicker, they are simply the faster, steadier tool.
So the kit, or the singles? For a whole room, the kit. It is counted so nothing runs out on day two, and one bundle order beats four separate ones. For everything else, buy the single. Extra screws for a repair. A roll of tape for one shower. An anchor set when the wall is solid and no stud is in sight. Each part of the system has its own page with the full spec if you want to check an item on its own.
What the kit does not do: it does not include the sealant, because joint length varies and sealant goes by the cartridge, not by the carton. And no carton of fixings rescues a bad substrate. Chalky render, timber rot, out-of-plumb framing. Fix the background first, then count the screws.

Fixing

One kit per ten sheets is the planning number. Set your lines at 300 mm, seat a washer under every screw, drive until flush (firm, not crushed), then tape and seal every joint. The full sequence is in our installation guide, free with a sample request.
