How to cut the foam after installing windows

How to cut the foam under the window sill

Today it is already difficult to imagine construction or repair work, where installation foam is not used. With its help a lot of problems are solved, because the foam acts as a thermal insulator, sealant, or used as a fixing substance.

Installation foam is highly durable and can not change its useful characteristics for many years, but if certain conditions. no ultraviolet rays. If you do not hide the foam from ultraviolet light, it quickly deteriorates, as a consequence, loses its useful properties.

Properties of assembly foam

This chemical product is a sealant based on ponopolyurethane, which includes isocyanate and polyol. It is a base, but different manufacturers may include different additives, such as catalysts, stabilizers, foaming agents and the like. The foam has high adhesion and expandability, allowing it to fill the entire space. The materials with which this foam forms a strong bond are as follows:

At the same time plastic or greasy materials, as well as wet surfaces adhere to such a foam to a much lesser degree. This, in turn, ensures that we do not apply it to places where it should not be. Although, to scrape away such a foam from such surfaces is still not easy.

Drywall

This material is fixed with metal or wooden profiles. In order to fix the drywall, you must first make a special framework. Sheets should be cut to size and fastened to a special frame. Crevices should be glued with reinforcing tape, and then putty these areas so that they become flat.

You don’t need any special skills to use assembly foam for this kind of work. It is enough to know how to insert the gun correctly and carefully spray the foam. The variety of materials makes it possible to choose the material to close the assembly foam, which is most suitable.

foam, installing, windows

Due to the variety of materials and their colors there is an opportunity to choose the material that will blend perfectly with the window and fit into the interior of the room.

The main thing is to take into account the characteristics of each material, as some of them do not withstand high levels of humidity, some do not like low and high temperatures. In order to get a quality job that will have a long service life, you need to take into account all the nuances.

If you are not confident that you can not work with the foam and close it yourself, it is best to seek help from professionals, who will do everything quickly, beautifully and efficiently. They can also tell you which material is best suited to cover the assembly foam in a particular room.

Putting process

Wait for the foam to expand and dry completely. When ready for work, it is wave-shaped and excess foam often appears in unusual points and positions. It is not possible to hide such fragments with plaster, so they are removed beforehand. For these purposes, the excess foam is trimmed with a small step deep into the wall to use putty.

Cut the assembly foam no earlier than 12 hours after application, but it is better to make sure of the drying time. These are indicated on the spray bottle.

Before applying plaster, apply ordinary masking tape around the areas to be worked on, in order to protect a clean, unmodified surface from the appearance of stains. Remove the tape after the plaster is completely applied and has dried.

Expediency of building foam processing

This insulation is a high quality sealant, whose main task is to fill all the voids and bond the surfaces together. Polyurethane perfectly connects two surfaces, among which can be brick, natural wood and even concrete. This material can be used as a reliable waterproofing and a means to combat extraneous noise.

High density and strength only show up in certain operating conditions. Due to the effects of rain, snow and the rays of the bright sun, the final characteristics will gradually deteriorate. After a few years of use under improper conditions, the foam will simply begin to delaminate, and voids of different diameters and cracks will form in the joint.

This situation is fraught with complete resolution. That is why experts recommend caulking joints with special solutions. After final curing, the foam acquires a characteristic light beige hue. If the material has become brown after some time, the process of gradual destruction can be considered complete. In such a situation it is necessary to clean the window opening again from the previously used sealant and carefully close all joints.

Sealing of joints

Principle of protection

If the master has decided to use putty to cover the foam material, then you need to follow a certain algorithm of action. Any manipulation can be carried out only after the foam is completely dry. This process usually takes 10 to 12 hours. If there are areas that protrude above the level of the insulating glass unit, then they must be carefully cut away with a sharp knife.

During this procedure, it is worth going a little deeper into the base. The surface must be cleaned of debris and coated with a layer of primer. When the applied product dries, you can apply the putty solution, but not a thick layer. After complete curing, the prepared construction mixture is applied again.

Strengthening

The surface must be grinded with emery paper, primed and painted. If a craftsman does not plan to use putty, the excessive protrusions are cut off flush with the PVC window. Use emery paper to remove any irregularities. In the final step, the only thing left is to paint the surfaces. For this purpose, it is desirable to use a compound based on acrylic.

The product is applied only upwards, gradually approaching the corners of the frame. If putty or paint is applied to the surface, the final service life of the formed joint will certainly not be inferior to the operation of the building itself.

Important! To putty the foam it is better to choose a frost-resistant material, which is freely available in modern building departments. Many of them are a powder, in which a certain amount of pure water is necessarily added, in order to obtain a solution of the desired consistency.

The filler is applied to the surface to be treated and carefully smoothed out. If the layer is too thin, then over time it can be covered with numerous cracks. The thickness of the finishing material should be at least 3 mm. To make the seams aesthetically appealing, it is better to use a construction mesh.

Classic mesh to improve adhesion

Using plastic panels

Caulking foam after the installation of plastic windows can also take place with other materials. One of the popular materials for finishing is plastic. Panels made of it are sold in ready-made form. All that is required is to saw off the desired length piece and fasten it to the wall. Such work will take much less time than using plaster, will not cause difficulties for the amateur. To accomplish the task, you will need to do the following:

  • Cut the necessary size pieces, which will be fixed with a lath of plastic.
  • Install the side panels. They are fixed at an angle of 90 degrees to the window, you can do 110 degrees. For better insulation the gaps can be filled with installation foam. The remnants of the foam must be cut off after it dries.
  • The gap between the slopes and the wall is closed with a f-rated rail.

Wondering what to close the foam outside the window, as well as inside the structure, it is worth knowing that in fact assembly foam, it is also a sealant from the subgroup of polyurethane foam.

But as part of it is still and stabilizers, foaming, and other additives such as catalysts, which assign it a unique characteristics.

The main indicators by which the foam for installation, is its viscosity, the primary, and the secondary expansion, viscosity, adhesion, in other words, adhesiveness to the surface, and the final yield volume.

It turns out that in order to understand what to fix the foam outside the window, we must first understand what exactly is this foam, and most importantly, what are the dangers and hazards may be unsafe for its functionality.

At the same time the foam can be in the form of a consistency with one component, and two-component compositions also have a place on the market. For better understanding is also worth saying that the assembly foam can also be summer and winter, professional and consumer, etc.д.

  • If you want to know how to cover the foam on the windows, especially outside, it is worth thinking about how to prevent it precipitation. Running into the large pores of frozen foam, the action of frost will inevitably freeze the water, and, properly, expand, tearing your insulant. Therefore it is purposeful to use waterproofing.
  • It is also important to protect the foam from water penetrating into it from the inside, which is especially dangerous in winter, in the form of condensate. In other words from the inside of the window is certainly worth installing a vapor barrier, though the market is full of a variety of materials.

However, the question of how to caulk the foam around the window, sometimes puts many in a baffle, because it tends to expand and go far beyond the limits that it is allotted. But in fact, this is not a problem at all, because even a child can cope with the task.

Wondering what to seal the foam on the outside of the window, as well as inside the structure, it is worth knowing that actually the foam, it is also a sealant from the subgroup of polyurethane foam.

However, it also contains stabilizers, foaming agents, and other additives like catalysts, which give it its unique properties.

The main indicators by which to evaluate the foam for installation, are its viscosity, the primary, as well as the secondary expansion, viscosity, adhesion, that is adhesion to the surfaces, as well as the final volume of output.

It turns out that in order to understand what to seal the foam outside the window, we must first understand what this is the foam, and most importantly, what the risks and threats may be dangerous to its functionality.

  • It is clear that nothing has been invented by mankind to be perfect, so the assembly foam needs to be protected from the environment. It is not very well tolerated a regular and continuous exposure to moisture, and from the UV light, that is direct sunlight, it can even crumble into dust and ashes.
  • If you need to understand how to cover the foam installation on the windows, especially outside, it is worth thinking about how to prevent precipitation on it. Getting into the large pores of solidified foam, the frost will inevitably freeze the water, and therefore expand, tearing your insulation. Therefore it is advisable to use waterproofing.
  • It is also important to protect the foam from moisture inside, which is especially dangerous in winter, in the form of condensate. That is a window inside the mandatory installation of a vapor barrier, the market is full of a variety of materials.

The appearance of the window, with an assembly joint open to all winds, is also simply not aesthetically attractive, the window will be untidy and unkempt, and the entire design in this case will go to hell, and this is yet another reason to search and understand what to seal the foam on the windows inside and outside.

How and how to scrape the assembly foam from a plastic window: start over

But it is necessary to begin from a little differently, in fact at first it is necessary to find out what to wash out the assembly foam from plastic windows because it holds firmly enough, sticking to the glass pane itself, and even more tenaciously, to a plastic profile of a window frame. It is clear that it would be optimal to remove the foam before it finally dries, but if the moment is missed, you should not get upset, because a good sawmaker can always find a way out of such a complicated situation.

Also on the market there are a variety of special purpose flushes, such as “Macroflex”, which do an excellent job.

But there are a lot of nuances, and that’s why real professionals recommend to make sure that the product won’t damage the plastic beforehand. Simply wipe an inconspicuous area of the window frame with the solution, and wait a few minutes.

If everything is in order, you can start cleaning, otherwise the idea should be abandoned.

Several difficult to handle, if the foam has hardened considerably and has become solid. But even in such circumstances there is no need to get upset, because there is always a solution.

You can try to soften the material with any solvents, and only then try to wipe it off. In addition, true craftsmen use generally simple ways, purely mechanically scrubbing off the foam, using a cut piece of plastic.

It will not be able to damage the frame profile in terms of hardness, but the foam will peel off quite easily.
