Preventing Open Seams
Open seams can occur for a variety of reasons during wallpaper installation. Fortunately, most are easy to prevent with proper preparation and installation techniques. Below are the most common causes and how to avoid them when installing Hannah Langford Designs Luxe Traditional Wallpaper.
1. Improper Wall Preparation
A properly prepared surface is essential for a successful installation. Walls with old paint, uneven patches, excessive porosity, or poor surface preparation can affect adhesion and create tension as the wallpaper dries, causing seams to separate.
To avoid this: Ensure walls are clean, smooth, dry, and properly primed before installation. Remove loose paint, repair imperfections, and follow all recommended wall preparation guidelines.
2. Wallpaper Drying Too Quickly
If the room is excessively warm or exposed to drafts from open windows, fans, or HVAC vents, the wallpaper may dry faster than the adhesive can properly cure. This uneven drying process can place stress on the seams, causing them to open.
To avoid this: Install wallpaper in a temperature-controlled room and avoid direct airflow until the adhesive has fully cured.
3. Insufficient Adhesive Along the Seams
Paper-based wallpaper requires even adhesive coverage, especially along the edges. If too little paste is applied—or if the edges begin to dry before installation—the seams may not bond properly.
To avoid this: Apply an even coat of wallpaper paste across the entire back of each panel, paying close attention to the edges without overapplying. When booking (folding) the wallpaper, carefully align the edges to keep them fully covered and prevent them from drying out. Follow the recommended booking time before installation to ensure proper adhesion.
With careful wall preparation, the correct amount of adhesive, and proper installation conditions, your wallpaper will have the best opportunity to achieve beautiful, long-lasting results.
