Downlighter cut out repair and liner systems
WHAT SIZES DO C-FIX COME IN?
C-FIX REPAIR comes in 60, 65, 70, 75, 80, 85, 90mm diameter cut out sizes.
C FIX LINER comes in a STANDARD (depth 9.5mm) or a DEEP (depth 12.5mm) both in 65,70,75,80,85mm diameter cut out sizes, if you are in-between diameter sizes, always use the size up.
HOW DO I KNOW WHAT SIZE C-FIX TO USE?
C-FIX REPAIR sizes are measured by the diameter of the cut out needed and are adjustable to your ceiling depth (up to 15mm).
C-FIX LINER sizes are also measured by the diameter of the cut out needed but come in a choice of two depths: STANDARD (9.5mm deep) and DEEP (12.5mm) according to the minimum thickness of you plasterboard ceiling.
HOW LONG DOES IT TAKE TO FIT C-FIX?
C-FIX LINER only takes seconds to fit and C-FIX REPAIR only takes a matter of minutes to fit. You will however have to wait for your filler or adhesive to become fully dry before use.
DO I NEED ACCESS TO THE CEILING SPACE TO FIT C-FIX?
No you do not need access to the ceiling space for either of our products. They are designed to fit from below.
WHAT TOOLS DO I NEED TO FIT C-FIX?
For C-FIX REPAIR you will need a drill/screwdriver, a small straight edge or ruler, a pair of pliers and a filling knife. You will also need some structural filler e.g. one coat plaster (not lightweight filler). All other materials are included in your kit.
For C-FIX LINER you don't need any tools, just some adhesive (decorators caulk is best).
HOW DO I USE C-FIX REPAIR TO REPOSITION DOWNLIGHTERS?
If you need to move your downlighter slightly (e.g. to align downlighters or if you are too close to a joist /obstruction) then C-FIX REPAIR allows you to move your cut out by up to 30mm. If you need to move your cut out more than 30mm we recommend using a small batten inserted and fixed into the ceiling space for support in the enlarged area you will need to fill.
DOES IT MATTER IF MY C-FIX LINER DOESN’T COME FLUSH WITH THE CEILING?
No, it doesn’t matter if your C-Fix Liner doesn’t come flush with your plasterboard, just choose the depth of your C-FIX LINERS (STANDARD or DEEP) so that they do not protrude past your ceiling.
C-FIX LINERS are designed to protect your ceiling from downlighter springs from above, they are protecting the top edge of your cut out the inside the ceiling.
