Professional Corner Molding FAQ - All Objections Addressed
What makes this corner molding better than standard trim pieces?
Our professional 90° inside corner molding features precision-formed angles that ensure perfect corners every time, integrated splash guard protection for enhanced moisture resistance, and UV-stable color finishes that maintain their appearance over time. Unlike standard trim that requires cutting and fitting, our molding provides consistent professional results with easy installation.
Can I use this molding in wet areas like bathrooms and kitchens?
Yes, our corner molding is specifically designed with splash guard protection for wet area applications. It's perfect for bathroom shower surrounds, kitchen backsplashes, and other high-moisture environments. The integrated splash guard design provides enhanced moisture resistance and helps prevent water infiltration behind the molding.
How do I choose between White and Brown finishes?
Choose Splash Guard White (BM 92.5003) for modern, clean applications and to complement white tiles, fixtures, or trim. Choose Inside Corner Brown (BM 92.5980) for traditional, warm applications and to complement wood tones, earth colors, or bronze fixtures. Both finishes feature UV-stable coatings that resist fading and maintain their appearance over time.
Is professional installation required or can I install this myself?
Our corner molding is designed for easy installation with basic tools and skills. The precision-formed 90° angle eliminates the need for complex cutting and fitting. However, for best results in critical applications like wet areas, professional installation is recommended to ensure proper adhesive selection, surface preparation, and waterproofing integration.
What adhesive should I use for installation?
Use professional-grade construction adhesive or polyurethane-based adhesive for permanent installations. For wet areas, use waterproof adhesive specifically designed for bathroom and kitchen applications. Mechanical fasteners can also be used in combination with adhesive for enhanced security. Contact us for specific adhesive recommendations based on your application.
How many pieces do I need for my project?
Count the number of inside corners in your project area. Each corner requires one piece of molding. For typical bathroom projects, you'll need 4-8 pieces. Kitchen backsplashes typically require 2-6 pieces. Add 10-15% extra for potential mistakes or future repairs. Our 10-piece bundles are perfect for most room projects with cost savings.
Can I mix White and Brown pieces in the same project?
Yes, mixing colors can create interesting design effects and help coordinate with different elements in your space. For example, use White pieces with white tiles and Brown pieces with wood elements in the same room. Our bundle options allow you to specify custom color ratios to match your design requirements.
What shipping options are available for corner molding?
We offer both local Damascus pickup and nationwide standard shipping. Local customers can pick up same-day or schedule delivery within the Damascus area. For nationwide shipping, we provide standard 3-7 day delivery with professional packaging to prevent damage. Express shipping options are available for urgent projects.

Do you offer bulk pricing for contractors and large projects?
Yes, we offer professional bulk pricing with significant savings on 10-piece and 25-piece bundles. Contractors can save 20-30% per piece with our multi-pack options. We also provide custom pricing for large volume orders and regular customers. Contact us directly for contractor accounts, volume discounts, and special pricing arrangements for commercial projects.
What's your return policy for corner molding?
We offer a 30-day return policy on unused corner molding in original packaging. Custom color orders and cut pieces are non-returnable unless defective. For defective products, we provide immediate replacement or refund. We work closely with customers during planning to ensure accurate quantity calculations and proper color selection to minimize returns and ensure project success.
