One、What adhesive should be used to fix the door without paint?
The frame of a paint-free door can be attached to the wall using polyurethane foam + sealant. Specifically, when dealing with large and irregular gaps, polyurethane foam should first be applied (avoid overfilling to prevent distortion of the frame due to expansion), and then the remaining gaps should be filled with cement mortar. The surface should be level, and 1 cm deep grooves should be left on both sides. Finally, apply glass sealant.
Two. How to fix a door frame without paint using adhesive.
1. First, thoroughly clean the primed door frame and the wall sections where it is attached, ensuring that no water stains or dust remain. This is crucial for proper adhesion between the door frame and the wall.
2. Apply the prepared adhesive to both ends and the middle of the door frame moldings, applying extra adhesive to the ends. Then, attach the moldings to the door frame and press firmly for several minutes.
3、only release the pressure after the door frame strip is completely secured, otherwise the bonding effect will be poor.
4. After applying the ready-mixed putty paste to the door frame of the paint-free door, proper maintenance is required. It is crucial to avoid moisture and external stimuli, as this can affect the adhesive's effectiveness.
