Formica® Laminate is a durable and functional surface suitable for any room of the home or commercial space. Formica® Laminate, when installed properly, can be used around sinks without any damage to the laminate. The step-by-step instructions below outline the proper tools and procedure to install a drop in (also known as top mount) sink.

 

Step 1: Obtain the proper tools

Drill
Drill bit
Jig Saw
Screwdrivers
Waterproof Caulk and Caulk Gun
Tape Measure
Ruler
Pencil
Safety Glasses
Gloves

Step 2: Measure and cut the hole for the sink

Place the sink upside-down on the counter top where it is to be installed
Allow clearance on all sides of the sink
Trace around the outside of the sink with a pencil 
Depending on the type of sink, determine where the cut line is inside of the traced outline
Follow directions from the sink manufacturer
Drill a hole on each corner of the cut lines
Using a jigsaw, cut straight down the cut lines

 

Step 3: The most important- gluing and attaching the sink

Apply a heavy bead of waterproof caulk along the entire edge of the hole for the sink
Drop in the sink and apply even pressure to each side
Follow the instructions for sink installation and attachments from the sink manufacturer
Remove any excess caulk

Proper sink installation is important to keep laminate looking great.  Also be sure the right type of glue is used for applying laminate to MDF to make a countertop.  A waterproof PVA or Contact Adhesive is recommended to keep edges sealed tight.

Formica Group has created videos on our YouTube channel to educate and inspire homeowners and professionals how to use Formica® Laminate.

Expert Tip: Currently, Karran offers several styles of undermount sinks that can be installed with a laminate counter.  Formica Group recommends that these undermount sinks be installed by a professional to ensure that the sink is installed properly and keeps a waterproof seal.
