GGCL Guide On How to install a preformed countertop

Installing countertops is easier than you might think, especially with preformed models. When it comes to kitchen remodelling, installing your own countertop is an opportunity for self-expression – and money savings. To help you do the job efficiently and with style, we’ve listed the nine simple steps for installing your new countertop, as well as all the essential materials you will need.

Materials required
here are some essentials for a typical L-shaped kitchen countertop with a cut-out for a sink or range top installation:

  • Countertop sections; order standard lengths. Your dealer should be able to mitre cut and machine the fastening-bolt T-slots (underside of the joint).
  • Fastening bolts (for drawing mitre joints tight)
  • Tube of sealant (for caulking joints)
  • End splash and/or end caps (kits, as required). These should be available from your dealer.
  • Non-flammable contact adhesive (for fastening end caps, unless kit has pre-applied adhesive for "iron-on" method)
  • White glue (for fastening "build-up" blocks)

Tools Required:

  • Jig Saw
  • Drill and Drill Bit
  • Block Plane
  • Belt Sander
  • Smooth File
  • Hand Laminate Trimmer with carbide cutter
  • C-Clamps (for holding "build-up" blocks and end caps or splash to glue and screw)
  • Safety Glasses
  • Tape Measure
  • Rubber Mallet
  • Level
  • Square
  • Hammer
  • Handsaw
  • J-Roller
  • Scriber-Compass
  • Adjustable Wrench
  • Screwdriver
  • Sandpaper
  • Caulk Gun
  • Heat-Conductive Aluminium Tape


Step 1: Fitting to Length
Check for proper length. Allow desired overhang. End caps should be used on all exposed ends (end cap kits). End splashes should be used where top butts wall (end splash kit). Additional material should be allowed to scribe for a tight fit to end wall.

Step 2: Cutting
Cover the area to be sawed with a strip of masking tape and draw a pencil line on the tape to serve as your cutting guide. Use a fine-tooth handsaw (10 to 12 point) and always cut into the laminate surface to avoid chipping. Sand or file the cut to ensure a smooth surface.

Step 3: Build-up
Place your countertop upside down on a flat surface. Choose strips of wood thick enough to allow the countertop surface to match the front build-up. Glue strips around perimeter of

Step 4: Applying End Caps
To apply end caps, set household iron at medium heat. Iron cap onto the end of the
countertop with a back-and forth motion. Let set for one minute, and then tap the cap carefully with a rubber mallet. Finish trimming with a fine file, applying pressure only on the up strokes. Complete instructions are included in the end cap kit. To apply end caps using non pre-glued end caps, apply a contact adhesive to both the substrate and the laminate. Roll laminate with a J-roller. Finish trimming with a fine file, applying only pressure in the up strokes. If using a Laminate trimmer with a flush trim carbide router bit, remove excess laminate and file smooth applying only pressure in the up strokes.

Step 5: Making Cutouts for Sinks or Range tops
Place the sink or range top rim on the backside of the
countertop, where the appliance is to be located. Mark all the way around the edge of the rim. Use a jig saw to cut the hole 1/4" to 3/8“smaller than the line. All cutout corners should have clean, chip-free radii. Apply two layers of heat-conductive aluminium tape around range topcut out.

Step 6: Joining Mitres
If your kitchen requires an L- or U-shaped top, pre-cutmitres should be joined at this point in the installation. Apply a bead of sealant to each mitred edge. Tighten fasteners only enough to hold them in place. Align front edges and tighten fasteners. Tap surfaces to align (use wood blocks to avoid damaging the surface). Then tighten fasteners securely.

Step 7: Scribing
countertop can be scribed to match the wall surface. The top is provided with a scribe edge on the backsplash for this purpose. Place the top on the cabinet. Use a scriber-compass to mark the top edge of the countertop, then belt-sand or block-plane to the line. This will contour the countertop to the wall. Put top in place, check for level and stability, and then secure to cabinets with wood screws.

Step 8: Installing Sinks
you may find it more convenient to install the sink faucets, 3/8“supply tubing and basket drain now, before dropping the sink into place. This is important if space behind the installed bowl is too tight for easy connection of plumbing fittings. All sinks must be sealed with sealant to avoid water damage to base material.

Step 9: Finishing Installation & Care
Remove excess sealant from sink area or end splash of your new countertop is highly resistant to staining, wear and heat. It is not, however, completely impervious to chemicals, scratches and hot objects.
