Wall decoration moldings are mainly used in three areas:
Ceiling Decoration:100-150mm wide plaster cornice moldings are used, adhered with quick-setting plaster adhesive, to cover pipe joints and enhance the spatial layering.
Wall Transition: 12mm thick wooden moldings are installed at the junction of the wainscoting and the painted wall, fixed with a pneumatic nail gun and white glue to prevent material expansion and contraction cracking.
Door and Window Finishing:U-shaped metal moldings are used to finish the aluminum alloy sliding door track grooves, typically 8-10mm deep, with an electrophoretic coating finish.
The installation of decorative moldings requires four steps:
Substrate Treatment: The moisture content of the concrete wall surface must be controlled below 8%, and the wooden substrate must be coated with a sealing primer.
Positioning and Laying Out: A laser level is used to mark the installation baseline, leaving a 2-3mm expansion joint at the joints.
Installation and Fixing: Plaster moldings are applied using a spot-bonding method with plaster adhesive, with no fewer than 3 bonding points per meter; wooden moldings are fixed with nails.
Joint treatment: Fill the joints of plaster moldings with joint compound; wood molding joints need to be beveled at a 45-degree angle.
