Masonite provides a range of doors, including solid core, flush, molded panel, and wood panel varieties, designed for both interior and exterior applications. Proper installation and finishing are crucial for maximizing performance and maintaining warranty coverage. This article details recommended procedures based on Masonite’s published resources, covering preparation, installation considerations, finishing techniques, and storage guidelines. The documentation emphasizes precise measurements and adherence to manufacturer instructions to ensure a successful outcome.
Door Selection and Specifications
Masonite doors are manufactured to precise tolerances, necessitating careful measurement during the selection process. The company offers architectural specifications for most of its doors, available for download to aid in project planning. These specifications detail recommended use, product construction, delivery, storage, handling, and regulatory compliance information. Selecting the appropriate door unit for a specific application is key to achieving optimal performance. Masonite doors are available in various styles, including solid core interior doors designed for sound reduction, and exterior doors featuring AquaSeal technology for enhanced weather resistance.
Pre-Installation Preparation
Before beginning installation, it is essential to ensure the job site is properly prepared. Doors should be delivered to the site after plaster, drywall, and concrete have fully dried. Storage requires a flat, level surface in a clean, dry, and well-ventilated building, protected from dirt, water, and physical damage. Adequate air circulation must be maintained, and the top door should be covered with a moisture barrier. Doors should not be exposed to extreme temperature fluctuations, humidity, or direct sunlight. Masonite recommends maintaining a humidity level between 25% and 55% relative humidity (RH) and a temperature range of 50°F to 90°F (10°C to 32°C). Doors should be stored at least 10 feet away from any heat source to prevent uneven drying.
Finishing Procedures
Field finishing of interior doors can be accomplished using various methods and materials. A clean, well-lit, dust-free, and climate-controlled work area is required. The work area should be protected from paint or stain exposure, particularly on carpeted surfaces. All necessary materials should be assembled before starting the finishing process.
For doors with AquaSeal technology, inspection of the sealant around panels and glass is necessary. Any wood dust or wood chips present on the sealant should be removed prior to applying paint or stain. Removal can be achieved using a soft to medium bristle brush or a rag dampened with mineral spirits.
Masonite notes that some paint and stain products may require additional coats to achieve adequate coverage and color matching on the AquaSeal sealant. If additional applications are needed, a cotton swab or thin foam/bristle brush can be used for precise application. It is crucial to follow the coating manufacturer’s warnings and instructions on all product labels. Masonite does not warrant coatings unless applied by Masonite directly, and any damage resulting from stain or paint application will void the door warranty.
Stain and Paint Recommendations
Masonite provides recommendations for finishing based on door panel type. The documentation categorizes doors into the following types: flush, molded panel, MDF panel, wood panel, French, and louver. The documentation indicates that all door types should be professionally finished.
Installation Guidance
The provided documentation highlights the importance of following installation instructions carefully to ensure a correctly installed door. While specific installation steps are not detailed within the provided source material, it is stated that Masonite offers installation instructions covering required tools, necessary measurements, and finishing procedures. These instructions are intended to align with Masonite’s warranty requirements. Replacing exterior doors with Masonite fiberglass doors or upgrading hollow core interior doors with solid core doors are cited as examples of projects where these instructions are applicable.
Warranty Information
Masonite offers comprehensive warranties on its doors, varying based on application (interior, exterior, or Entry Systems with sidelites/transoms). The company has over 80 years of experience in the building products industry and aims for customer satisfaction. Warranty details are available for download and cover energy efficiency, ENERGY STAR® compliance, and regulatory requirements. Doors installed correctly can meet ENERGY STAR® requirements by region.
Energy Efficiency and ENERGY STAR®
Masonite is committed to energy efficiency and works with the ENERGY STAR® program. Energy-efficient doors can potentially save families approximately one-third on their energy bills. Masonite doors, when installed correctly, can meet ENERGY STAR® requirements, with specific requirements varying by region. Charts detailing these regional requirements are available from Masonite.
Post-Installation Considerations
All doors must be finished within seven days of installation. This timeframe is critical for proper adhesion and performance of the applied finish. The documentation reiterates the importance of adhering to manufacturer instructions for both installation and finishing to maintain warranty validity.
AquaSeal Technology Specifics
Masonite’s DuraStyle wood doors feature AquaSeal technology, which incorporates a silicon-based sealant around the perimeter of panels and glass. This technology is designed to provide long-term performance and aesthetic appeal. However, the documentation emphasizes the need to remove any wood particles from the sealant before applying paint or stain to ensure proper adhesion and finish quality.
Conclusion
Masonite doors require careful attention to detail throughout the selection, installation, and finishing processes. Proper preparation of the job site, adherence to manufacturer instructions, and timely finishing are essential for maximizing performance, maintaining warranty coverage, and achieving a high-quality result. The availability of detailed specifications, installation guides, and finishing recommendations from Masonite supports a successful project outcome. The company’s commitment to energy efficiency and ENERGY STAR® compliance further enhances the value of its products.
