Plaster and putty foam – what you need to know?

Plaster and putty foam are essential tools for priming surfaces for painting. These supplies are necessary to create even, smooth surfaces that guarantee perfect paint application and appearance. Comprehending the distinctions between putty foam and plaster, along with their respective applications, can greatly enhance the caliber of your painting endeavors.

A classic material for coating walls and ceilings is plaster. It is composed of sand, water, and a binding agent—typically gypsum. Plaster makes a great paint base because it has a hard, durable finish that is sandable smooth. It works especially well for covering large surfaces and can be applied thickly to fix significant surface flaws.

Conversely, putty foam represents a more contemporary approach. It’s a handy tube or can product that’s lightweight and simple to use. For patching up tiny holes, cracks, and other flaws, putty foam is perfect. As it dries, it slightly expands, guaranteeing a smooth finish and tight seal. Because of this, it’s ideal for touch-ups and intricate tasks requiring accuracy.

The condition of the surface and the extent of the repairs required will determine which material is best for your project. Because plaster is stronger and more durable, it’s usually a better option for larger, more extensive damage. Putty foam is more useful and effective for minor repairs and fast fixes. Your painting endeavors will look more professional if you know when and how to use each material.

The ability to finish the foam

Foam is made up of simple foam, also known as foam or ostral foam. Foam gains the following qualities when it is processed using a unique thermal method:

  • High strength, which is several times higher than the usual foam.
  • Smooth coating and homogeneous structure.
  • Almost complete lack of moisture absorption.
  • High level of vapor permeability.

Penoplex adheres to surfaces less firmly than polystyrene. This means that using standard technology to apply such a material will be incorrect. This will result in the reinforcing mesh and insulation putty lag. The foam is plastered even though it isn’t meant to be used for wet lining. The technology of decoration has been developed by experts, ensuring high strength and a quality outcome.

Stages of plastering

The following steps make up the foam complex’s cladding process:

  1. Preparatory work.
  2. Surface reinforcement.
  3. Approaching a leveling layer.

Since each step is crucial to the implementation, it must be handled carefully.

Preparatory work

The first thing you need to do is decide which plaster is going to be used for the foamyplex. Experts advise utilizing generic blends of well-known brands. Nonetheless, specific formulations are available for use with polystyrene foam plates. A plaster-red Ceresit mixt is one of these items.

The composition is made in accordance with the directions on the package, but there is one very crucial detail regarding consistency that should not be overlooked. The composition consistency for the installation of a reinforcing grid should be marginally less than what the manufacturer advises.

The solution needs to be as liquid as possible for alignment. You will need roughly 4 kg of composition per 1 m2 to install the reinforcing mesh and 6 kg for the leveling layer.

You must get ready the following supplies and tools before plastering the foamplex:

  • glue for polystyrene foam and the connection of the reinforcing mesh;
  • deep penetration primer;
  • fiberglass reinforced mesh;
  • two spatulas of different sizes and a grinding grater;
  • perforated corners.

In order to remove any potential irregularities and surfaces, foam grout is also used during the preparation stage. Work should not be rushed because the preparation work directly affects the final outcome.

Reinforcement process

The installation of a plastered grid is a crucial step. Their life will be greatly impacted if plastered walls crack without it. In order to install the mesh, you must first apply a layer of glue to the foam, about 3 mm thick, and then glue the product to it. Additionally, while carrying out this kind of work, the following details need to be considered:

  • It is necessary to press the grid into the plaster no more than half, but the entire surface of the product should be immersed in the adhesive composition. A plaster solution is applied in several stages. Often this is done by stripes no more than 1 m, since it is such a width that has a facade grid.
  • The reinforcing mesh should be glued only on a fresh solution, it must be immersed with a smooth spatula.
  • The lanes of the product are overlapped, with a allowance of at least 10 cm. You need to work especially carefully with the corners, from which reinforcement usually begins. To properly glue the angle, you need to use a strip of 30 cm wide, bend it in half, crush it to the corner and press it into the adhesive solution.

The entire surface needs to be grouted after the reinforcing layer dries. You can use a grater with sandpaper or a grinding machine for this. Grouting is done in counterclockwise circular motions with little to no tool pressure.

It is important to remember that the weather has a direct impact on when the solution dries. It is best to wait at least a day in cold weather; in hot weather, it will be sufficient to wait a few hours before beginning the grouting process.

Approaching a leveling layer

Plaster alignment is the next step in the process. The same universal solution that is used for reinforcement is applied here. Using a spatula, the composition is applied and evenly distributed across the wall. The layer’s thickness shouldn’t be greater than 3 mm.

Foam grouting is the last process. It is only done after the solution has dried completely and is done in the same manner as when reinforcing. It will require at least one day to completely dry, and possibly longer in the winter. However, you shouldn’t wait too long because the grout won’t work and the solution won’t harden after 4 days.

Plastering is thought to be finished when the entire surface has been worked on, at which point you can putty the rooms.

A smooth, polished finish is the result of knowing the functions of putty foam and plaster when working on any painting project. While putty foam works well for filling in cracks and crevices and providing a perfect surface for painting, plaster is usually used to create a solid, even surface on walls and ceilings. Understanding the differences between the two materials and their respective applications can save time, money, and greatly improve the appearance and longevity of painted surfaces. You can navigate their uses, advantages, and best practices with the aid of this guide.

The choice of putty for the foam

Using particular putty mixtures, surfaces are finished by cladding them with putty. The surface that putty will be applied to determine which kind to use. Certain compositions come in powder or paste form. Past-shaped mixtures are separated into oil, silicone, and acrylic and then mixed together.

Powder or acrylic-based compositions will work best for a foamyplex. You can consider silicone options for internal cladding.

The degree to which the putty’s connecting elements are high-quality is another factor that must be considered when selecting it. The quality of the binding components directly affects the solution’s resistance and ability to withstand cold, moisture, and different types of atmospheric precipitation.

It is advised to speak with the seller when selecting putty on foam. He will assist in selecting a solution that can bear the weight better. Additionally, keep in mind that facades cannot be painted with facing mixtures, so it is best to avoid saving money because doing so would require redoing the entire project.
