How to glue drywall to the wall using polyurethane foam

It is not always necessary to use strong adhesives or a complete framework to attach drywall to a wall. Polyurethane foam can be a useful and effective solution in certain situations. When dealing with uneven walls or needing a simple and fast installation process, this method comes in handy.

For a solid connection between the drywall and the wall surface, polyurethane foam serves as both an adhesive and a filler. It’s a flexible solution that performs well in a range of situations, from minor repairs to home remodeling. It’s also more manageable than conventional techniques, which makes it a great option for do-it-yourselfers.

We’ll walk you through the process of using polyurethane foam to securely attach drywall in this guide, guaranteeing a smooth and polished finish. This method will help you accomplish fantastic results with the least amount of trouble, whether you’re working on a big project or a small repair.

Polyurethane foam adhesive is a fast and effective way to adhere drywall to a wall that makes installation easier and guarantees a solid bond. When conventional adhesive options are too messy or time-consuming, this technique comes in especially handy. It is the perfect solution for both professional and do-it-yourself projects because you can achieve a secure attachment with little effort and cleanup by applying the foam directly to the drywall and pressing it onto the wall.

When can you glue drywall using polyurethane foam?

This approach should be used in the following situations:

• Quick installation is required. The final setting of the composition occurs within 24 hours, which is significantly less than that of many putty mixtures.
• Small amount of work. It is not recommended to lay on polyurethane foam if the total area involves placing more than 8 sheets on one surface. The fact is that fitting parts is the most difficult part of the technology.
• A small number of small areas. Blank walls are preferable for pasting, the presence of window and door openings significantly complicates the work. It is not always possible to place small sections in a single plane, which leads to the need to lay an additional layer of plaster.
• Minor surface irregularities. Polyurethane foam is well suited for small defects in the base and height differences of no more than 3 cm. To achieve perfect alignment of very crooked walls, it is better to use the frame method.
• The need to preserve area. Gluing eliminates the reduction of space, which is especially important for small rooms.
• Finishing concrete or brick bases. The technology is used on flat walls that are not suitable for independent decorative cladding.

Professional adhesive foam is advised for drywall boards that have a minimal amount of expansion. The composition is applied with a specialized gun; it is available in tubes.

Installation methods

Depending on the state of the surface, various techniques are used to glue gypsum board to the wall.

The first step in any method is to prepare the base:

1. The surface is cleaned of old decorative material, if any, dust and dirt are removed.
2. The condition of the coating is assessed. It is recommended to dismantle all layers of plaster that pose a risk of collapse.
3. Cracks and fissures are sealed, special attention is paid to damage on load-bearing walls. If the defect is through, more effort is required to completely eliminate the appearance of cold bridges.
4. Areas damaged by mold and mildew are cleaned and treated with special compounds.
5. A primer is applied. The mixture will improve adhesion. This procedure is especially relevant when working with a concrete wall, in such a situation a deep-penetrating solution is used.

You can start the main work after the surface has dried.

Guidance! Although laying on foam is a good way to level gypsum board slopes, it is not recommended in high-humidity regions.

Perfectly flat walls

Attaching a sheet of drywall to nearly perfect bases is not difficult at all. You can complete the task with just your hands and no sophisticated machinery or tools.

1. The starting area of ​​work is determined. It is advisable to start fastening the slabs from the corner.
2. For the process, it is necessary to prepare wooden spacers. The structure consists of a bar and a flat board about 100 cm long, to which several pieces of the slat are screwed, the bar will rest against them.
3. A sheet of plasterboard is laid next to the place where it is supposed to be fixed. For greater convenience, the slab is placed on an elevation from the floor. Wood fragments or bricks are suitable as a spacer.
4. A can of polyurethane foam (it is better to use Giprok) is shaken well and installed in the gun. If a simple tube is used, then a distribution nozzle is screwed on.
5. The mixture is applied evenly in a thin layer to the edges of the part, and then in a zigzag pattern to the rest of the surface and kept for 10-15 minutes so that the composition reacts.
6. The slab is carefully lifted, placed in place and glued. Using a level, alignment is immediately carried out.
7. Stops are set until the material is fixed.
8. The remaining areas are covered similarly, with an orientation towards the first element. It is taken into account that gaps are formed between adjacent parts.

You can complete small areas quickly thanks to technology. For this, each wall’s work is completed in parallel.

Surfaces with minor defects

Plasterboard panel installation takes longer on bases with small flaws or height variations.

1. Sheets are pre-drilled for dowels. It is necessary to make about 12 holes at the same distance from each other.
2. Fixation points are transferred to the wall and also drilled.
3. The facing material is placed in place and screwed onto self-tapping screws, under the heads of which washers are placed.
4. New holes are drilled next to the existing holes at a distance of 5-8 cm, equal to the diameter of the device for distributing the polyurethane foam.
5. The solution is carefully introduced inside. It is taken into account that excess will contribute to expansion.
6. Using a level, the part must be aligned, for this, the screws are tightened in the right direction.
7. Self-tapping screws are freed from washers and fixed flush. Protruding sections of foam are cut off.

Although this method requires a lot of work, it can correct even significant elevation changes.

It is a useful and effective technique to attach drywall to walls using polyurethane foam. Even individuals who are new to DIY projects can accomplish this simple process because it doesn’t require advanced skills. Compared to more labor-intensive methods, this technique saves time because the foam sticks quickly and firmly.

The superior insulating qualities of polyurethane foam are yet another benefit of using it. It facilitates the formation of a strong bond between the drywall and the wall, which can enhance the room’s overall insulation. This technique works particularly well on slightly uneven surfaces because the foam can fill in any gaps and imperfections to produce a smooth finish.

You can improve the look and use of your space by installing drywall with stability and durability by following the suggested steps. To guarantee the best outcomes, always remember to measure precisely and work carefully. Using polyurethane foam, you can successfully finish your drywall project and prepare your walls for the subsequent finishing steps.
