3. What Materials and Tools are Needed for Installing Moldings?
Before starting work, make sure you have everything you need:
-
Tools:
- Tape measure, measuring tape, square, and pencil for marking.
- Knife or special saw with a fine blade for precise cutting.
- Spatulas for applying glue.
- Level or laser measurer to check the evenness of the installation.
- Vacuum cleaner or broom for cleaning the surface.
-
Materials:
- The chosen type of moldings (gypsum, polyurethane, polystyrene, or wooden).
- Glue for moldings: The choice of glue depends on the material of the moldings. For example, gypsum moldings require special gypsum glue, while polyurethane ones need universal acrylic glue.
- Sealant for filling joints and providing additional strength to the installation.
4. Choosing Glue: What to Use to Glue Moldings and What is the Best Surface to Glue Moldings To?
The correct choice of glue is the key to successful installation. Here are some recommendations:
- Gypsum Moldings: Use special gypsum or cement glue. It provides strong adhesion and takes into account the weight of the material.

- Wooden Moldings: It is best to glue using PVA glue or mounting glue for wood, which guarantees the stability of the attachment.
- Special Cases: If you need to glue moldings to tiles or other smooth surfaces, pay attention to special adhesive systems that provide reliable adhesion even to nylon or ceramic coatings.
5. Step-by-Step Instructions: How to Glue Moldings
Below is a detailed instruction for those asking: how to glue moldings and how to attach moldings to different surfaces.
Step 1: Surface Preparation
- Cleaning: Thoroughly clean the surface of the ceiling, walls, or tiles from dust, dirt, and old coatings.
- Base Preparation: If necessary, apply primer or putty for better adhesion.
Step 2: Marking and Measuring
- Marking: Use a tape measure, square, and pencil to accurately mark the places where the moldings will be attached.
- Calculation: Measure the length of the walls and ceiling, leaving extra material for cutting and corner joints.
Step 3: Preparing the Moldings
- Cutting: Using a saw or special scissors, cut the moldings into segments of the required length. If you are working with gypsum or wooden moldings, it is important to consider the corner joints.
- Edge Treatment: If necessary, trim or sharpen the edges for a perfect joint.
Step 4: Applying Glue
- Glue Application: Using a spatula, evenly apply glue to the back of the molding. Pay attention to what to use to glue moldings – choose glue according to the material.
- Control Quantity: Do not use excessive glue to avoid overflow beyond the molding, but do not skimp either, as this affects the strength of the joint.
Step 5: Installation
- Gluing: Carefully apply the molding to the marked surface, pressing it evenly. If you are wondering how to glue moldings to a wall or how to attach moldings to a ceiling, it is important to follow the exact markings.
- Fixation: Use a level or laser measurer to check for horizontal and vertical alignment. In some cases, temporary fastening may be required using special brackets or clamps.
Step 6: Finishing Touches
- Sealing Joints: After installing the moldings, fill the joints with sealant or a special mixture to give a finished look.
- Final Treatment: If necessary, perform painting or varnishing to match the color of the moldings with the overall design of the room.
6. Features of Installing Moldings on Different Surfaces
6.1 How to Glue Moldings to the Ceiling
- Tips: Before installation, check the evenness of the ceiling. Use a laser level for accurate marking. Pay special attention to corner joints – they should be perfect for a flawless appearance.
- When to Glue: It is best to glue moldings after completing the main renovation work (painting, puttying) to avoid disturbing the fresh finishing layer.
6.2 How to Glue Moldings to the Wall
- Tips: Wall surfaces should be even and clean. If the walls have irregularities, they need to be leveled beforehand using putty.
- Features: When working with wooden or gypsum moldings, follow the manufacturer’s instructions for glue to ensure a strong connection.
6.3 How to Glue Moldings to Tiles
- Tips: For tiles, use special glues that provide reliable attachment to smooth and ceramic surfaces. Before installation, treat the tile with a special primer.
- Importance: Surface preparation is key – without it, even the highest quality glue will not provide the necessary adhesion.
7. Additional Tips and Recommendations
- Work Planning: Always plan your work in advance, measure the area, and calculate the necessary amount of material.
- Glue Testing: Before the main work, conduct a test gluing of a small sample to ensure the compatibility of the glue with the molding material.
- Surface Protection: Use painter’s tape to protect adjacent surfaces from excess glue.
- Temperature Conditions: Avoid gluing in high or low temperatures, as this can affect the drying process of the glue.
- Safety: Work in a well-ventilated area and use eye and hand protection.
