READ this entire installation guide before beginning your installation. LICO is not responsible and will not be held liable for project failures if installation guidelines are not followed. ACP recommends that you install these tiles over an existing substrate to ensure proper structural integrity. Signature Plus panels are not intended to be attached to raw concrete, poured concrete walls or concrete block basement walls.

FOR SHOWER, TUB OR DIRECT WATER ENVIRONMENTS

Although Signature Plus panels are 100% waterproof when used with sealant in the seams, we recommend you follow your local building codes for wet environments like shower and tub enclosures. In a tub or shower area, existing ceramic tile walls can be covered with no additional preparation. Otherwise installation over a waterproof substrate is required, such as Cement Board®, Schluter Kerdi Board®, GP Densheild®, JohnsManville Go Board ®, Hardiebacker®, WPBK Triton®, Fiberock® and equivalent products. Always follow manufacturer's installation instructions to create a waterproof enclosure.

NOTE:

Lico is not responsible or liable for any labor costs or damaged product incurred as a result of improper installation. All product defects are covered under our 10-year limited warranty.

Due to manufacturing variations. we cannot guarantee an exact color match from lot to lot. Prior to installing Signature Plus panels and trims on your walls, please unpackage & lay out all purchased product to ensure color consistency.

Preparation for installation

Before starting, make sure all surfaces are clean, dry, smooth and free from dust, grease, wax, etc. Wipe the back surface of the panels with a clean cloth to remove dust or debris, Perform a "dry layout" prior to applying adhesive.

Measure walls & check for level and square. depending on dimensions and room construction, you may need to trim some panels accordingly.

Install the back wall panels first, from left to right (1&2). Next, install the side wall panels (3 & 4). Note that panels 1 & 2 will connect together with tongue and groove, so pay attention ahead of install so that connections works.

Apply adhesive to the back of the first panel.

Using recommended adhesive, apply a 1/8″ bead around the perimeter of the panel, about 1″ in from the edge. Then, apply rows of adhesive every 4-6″ apart in a typical "S" pattern.

Insert sealant from end to end into the deeper channel of the first inside corner trim. Panel 1 will be inserted into this channel.

Slide the inside corner trim onto panel 1.

Make sure it is tight into the corner. Before installing panel 2, be sure to put a bead of sealant along the tongue and groove edge of panel 1. Like with panel 1, apply adhesive to the back of panel 2.

Insert sealant into the second inside corner trim from end to end. Slide the inside corner trim on panel 2. Like panel 1, make sure it is the deeper channel as that is the one that panel 2 will go into.

Make sure the corner trim and panel is tight in the corner. Detail showing the tongue and groove connection.

Slide the panel to the left so the tongue and groove of the panel edges click together. Wipe off any sealant that squeezes out or add more if needed.

There is enough depth to the inside corner trim to allow plenty of panel movement to fit the panels together. Also, check for any sealant that may squeeze out of the inside corner trims. That will need to be wiped off or if lacking, you may need to apply more.
