Installation & Handling Guidelines
⚠️ IMPORTANT: NATURAL STONE PRE-SEALING & MORTAR PROTOCOL
-
Pre-Sealing Essential: Carrara marble is a natural porous stone. Apply a penetrating natural stone sealer to the trim pieces prior to grouting to prevent grout haze and pigment absorption.
-
Pure White Thin-Set Mortar Required: Set Carrara marble trim using a polymer-modified pure white thin-set mortar (ANSI A118.4). Gray mortars will shadow through translucent light marble and permanently discolor the stone.
-
Mitering Corners: Cut 45-degree corner miters carefully using a wet tile saw equipped with a continuous-rim diamond blade designed for marble.
-
Grout Joint Placement: Butt trim pieces neatly along the finished edge of the main tile field, maintaining a consistent 1/16" to 1/8" grout line.
Care & Maintenance
-
Routine Cleaning: Clean regularly with warm water and a neutral pH natural stone cleaner. Avoid vinegar, bleach, lemon juice, or abrasive scrubbers, which will etch polished marble surfaces.
-
Periodic Resealing: Reapply a quality penetrating stone sealer every 1 to 2 years (or more frequently in heavy shower wet areas) to maintain water repellency and stain defense.

Frequently Asked Questions
Does Carrara White quarter-round trim require sealing?
Yes. Being natural marble, it is porous and should be sealed with a penetrating stone sealer before grouting and maintained periodically.
Can this quarter-round trim be used in wet areas like showers?
Yes. It is widely used to trim shower niches, window returns, and wall edges, provided it is set with white thinset mortar and properly sealed.
Why is white mortar required for installation?
Carrara marble is slightly translucent. Gray thin-set mortar can show through the stone, causing dark discoloration or shadows along the trim.
