On the underside of your worktop, measure the area to be protected by the moisture barrier - this should correspond to the placement of your appliance. Add a small margin to your measurements - this will ensure that the moisture barrier covers the entire area exposed to radiant heat.

Step 2: Prepare your surface

Thoroughly clean the underside of your worktop using a lint-free cloth. Strong adhesion requires a clean, dry surface - ensure you remove any dust and allow to dry completely.

Step 3: Cut to size

Unfold the Unika Heat and Moisture Barrier aluminium side up and cut (or tear) to size using your measurements, making sure to include the additional margin.

Step 4: Check the fit

With the backing paper still attached, position the moisture barrier on the underside of your worktop to check the fit before applying. Use masking tape or a pencil to mark the edges of the barrier – this will help you align the moisture barrier accurately once you have removed the backing.

Step 5: Peel & position

Start your application by peeling back a small portion of the release paper from one short edge - do not remove all at once. Align the exposed adhesive to the appropriate edge on the underside of your worktop - use your marks as a guide. Gradually peel away the rest of the backing paper while pressing the sheet into place - work from one side to the other to avoid trapping any air.

Step 6: Smooth & press

Use a rubber roller or flat block to fix the sheet firmly in place. Apply even pressure across the entire area to activate the pressure-sensitive adhesive bonds - check that every edge is firmly secured to your worktop and trim any excess barrier with scissors or a utility knife if necessary.
