Let’s explore the different methods and determine which one is most effective for you.

Why take off their putty

The old coating is frequently saved in its original location before plastering or adhering wallpaper to the walls. Sadly, there is a significant difference in the operational and technical qualities of newly completed work and previously completed work. Putty begins to lose its strength, resistance to abrasion, and ability to withstand changes in humidity and temperature after many years of use. Even seemingly trustworthy and long-lasting coatings can simply flake off during final work.

To guarantee the dependability and strength of the new finishing layer, the old putty must be removed. The master’s most crucial task is to remove putty from the walls because the quality of the finished product is determined at this stage. The ceiling is the most exposed area in the space because all of its flaws are more severe and its vertical surface has adhesion to finish violations.

It is nearly hard to make a new finish perfectly even if you do not save the walls and ceiling from the old putty. Serving and fresh material are not well connected to one another and have uneven plasticity over extended periods of time. Furthermore, it is challenging to remove flaws and irregularities from coating surfaces, even with careful grinding.

Plaster and putty consumption will rise as a result, and working hours will rise. The worst part is that all the manipulations will need to be redone if the new finish suddenly collapses in the near future. As a result, more attention needs to be paid to surface preparation beforehand.

The initial stage of work with putty

Prior to anything else, the putty needs to be inspected for quality and its removal need to be determined. Experts recommend using a spatula to gently tap the walls; if there is no sound, the finish needs to be removed. The subjectivity of the approach is the unity of complexity because not everyone can truly appreciate the extent of sonority and deafness. There is a chance of error with this assessment methodology because the audible tone will vary depending on the kind of material, how it is applied, and how thick the layer is.

It is imperative that the old putty be removed if:

  • The finish has gained an unpleasant, abnormal color;
  • there are bloating in several places;
  • traces of fungus, mold appeared;
  • When tapping, the pieces of material break off, crumble;
  • there is a desire and the ability to carry out the finish “from scratch” and make a new coating as durable as possible.

It can be left on the walls or ceiling if the repair was done recently and there are small chips, pits, and cracks in the new putty. The damaged areas need to be cleaned, primed, and then reapplied. When it is intended to continue cleaning their putty, specific steps are taken in advance:

  • All fasteners are removed from the walls, hangers, nails, brackets are removed;
  • Furniture is pushed or carried out, like equipment, other large things;
  • Everything that remains in the room is covered with polyethylene to protect objects from building debris and dust;
  • The floor is covered with a film or newspapers, attaching them to the skirting boards with painted tape;
  • The entrance to the room is closed with a wet cloth so that plentiful dust does not penetrate into the neighboring rooms.

Putty removal tools

In order to thoroughly and swiftly clean putty surfaces, you must first gather all required equipment and supplies:

  • spray;
  • ladder;
  • protective gloves, glasses, respirator;
  • sandpaper or grinding machine;
  • punch with nozzle-lobe;
  • grinder;
  • bucket;
  • acute metal spatula;
  • a chisel and a hammer;
  • roller or sponge;
  • scraper;
  • Metal brush.

With the correct techniques, removing putty from walls and ceilings can be a simple task. From using basic hand tools like scrapers and putty knives to using more sophisticated techniques like chemical strippers and heat guns, this guide covers all the necessary techniques. Additionally, we’ll offer advice on how to ensure a smooth, clean finish and prepare the surface for new finishes. Whether you’re taking on a minor fix or a large renovation, following our detailed instructions will help you finish the project with minimal hassle and professional-quality results.

Ways to clean the walls of putty

There are various approaches you can take when dealing with putty walls. Experts recommend using one of the appropriate approaches, but if necessary, utilizing sophisticated measures.

Mechanical method of removing putty

The manual wall cleaning method takes a lot of time. It is typically applied in these circumstances:

  1. The plaster layer is not too thick and easily removes with the help of simple tools. Typically, the material is scrapped with a hard brush, a blade of a spatula, a scraper. To reduce dust formation, the wall is regularly irrigated with water.
  2. Putty holds tightly on the basis and is poorly lends itself to separation by a spatula. In this case, it is better to use a chisel with a hammer. It is possible to cope especially well if the purified surface is not too large (less than 5 kV. m).
  3. The strength of the adhesion of putty with the base is low. Usually quite easily disconnected from the surface, the material on a gypsum basis. Acrylic or silicone mixture can be cleaned only with the help of power tools, since it is expressed with the substrate tightly.

The best method for getting rid of putty is to use a grinder or grinding machine. You can clean a sizable portion of the ceiling or walls in a brief amount of time. A perforator fitted with a specific nozzle can also be used. Having a pneumatic pistol will be beneficial in intricate areas as it can efficiently remove any leftover material from corners and crevices. A milling is used to remove particularly strong putty or coating that is applied in multiple layers.

Chemical method against the old putty

An order of magnitude faster removal of the old finish can be achieved with the use of water and various homemade methods. In this instance, the tools and devices you’ll need are a large plastic pelvis, a wide-nozzle sprayer, and a sponge or brush. Using regular starch is the most straightforward method.

It is applied to the wall using a brush, sponge (roller), or sprayer after being dissolved in warm water (about two tablespoons per liter of liquid). Using a spatula or tapping, remove the finish after impregnation. After working on the remaining surface, begin with the areas that are causing the most trouble.

The walls can also be cleaned with a copper sulfate-based solution in addition to starch. 50 g of sulfate powder and one liter of hot water are needed for its preparation. Using a sponge, the composition is applied to the wall, thoroughly soaking the finish. Putty needs to be saturated with a medium in order for it to effortlessly separate from the base.

Fast removal of putty

Measuring the putty layer’s thickness is a good idea in order to estimate the amount of work and select the best way to complete it. This can be accomplished experimentally by, for instance, sprinkling a tiny area of the coating with water and measuring the amount of wetness that results. It is preferable to use specific chemical solutions or move a power tool along the putty’s surface if plain water was insufficient to moisten the entire thickness of the material.

From the ceiling

Working with the ceiling is very awkward. To avoid spending a lot of time in agony with a spatula in an awkward position, you should remove putty chemically. After diluting the starch mixture and thoroughly spraying the ceiling with a spray gun, use a spatula to clean the putty. Working with a grinder will be much faster and simpler if one is stocked.

With a grinding machine, you must begin the main stage right away rather than wetting the base in any way. Because there is a lot of dust, you should protect your health beforehand by getting the best respirator and safety glasses.

From the walls

It is more difficult to repair new buildings in apartments in the old fund because the walls are coated with a thick layer of putty and plaster. The coating’s walls and surrounding area must be thoroughly cleaned in order for the finish quality to be at its best. The most troublesome spots, where the material is just slipping off the substrate, are where they start their work. Disconnect the plaster from the ceiling and plate seams using a spatula. Use a starch solution or water spray to finish the surface if needed. Sandpaper is used to clean the putty residues after the majority of it has been removed.

It is worthwhile to use power tools to clean areas where the material is excessively tight. A grinder with a diamond disk works great for this purpose because it can remove material layers that are uniform in thickness. Hold the tool so that the wall and the circle are parallel. Once the majority of the putty has been removed, a large grain is sandwiched between the remaining pieces. After the job is finished, use a damp sponge to wipe down the walls to get rid of any dust or leftover construction debris.

Removing old multilayer putty

Power tools, such as a grinder, a grinding machine, and a perforator with a special nozzle, will aid in the resolution of such a major issue. For instance, the plaster may be "tapped" by a perforator to cause it to separate, and the thick layer can then be removed with a chisel or nozzle-lobe.

Cleans the walls of the Bulgarian multi-layer coating no less qualitatively with a diamond circle. There is always a lot of dust involved when using a power tool, so you should plan ahead and consider wearing personal protective equipment.

Cleaning the walls of the new putty

Generally speaking, strong tools are not needed to solve this problem. All that is needed to separate the coating from the substrate is a light misting of water or starch solution on the walls. It can be cleaned with a spatula or metal brush after 15 to 30 minutes, and any residue can be wiped with coarse-grained sandpaper that is fixed on the bar.

After grinding

Putty typically settles with the base quite evenly and firmly following grinding. Using makeshift tools to remove such a coating is not always feasible. You must take drastic measures, like using specialized equipment. The following should be the order of action:

  • attach a chisel to a certain area, holding it at an angle of 45 degrees;
  • knocked down the chisel with a hammer, forming a swelling area of ​​putty;
  • Remove the chisel, once again carefully squeeze around the site with a hammer;
  • pick up a piece of coating with a sharp edge of a metal spatula and separate it;
  • Remove the remnants of putty.

An even quicker solution can be found if a perforator or grinder is present. The tool is installed at a slight angle to the surface, and a small notch is made in the wall. They grind all of the putty from the processed area slowly.

With GKL

Putty coating on drywall can be removed without much trouble. It will be sufficient to mist the sheets with clean water using a spray gun or to wipe them down with a damp sponge if they were covered in indestructible mixtures. The putty is cleaned using the spatula’s edge following swelling and impregnation, which occurs after approximately thirty minutes.

You must prepare a solution of starch and water that is about +35 degrees in order to create building mixtures with higher moisture resistance. The latter is added to the water and thoroughly mixed so that the mixture dissolves like liquid clayer rather than sinking to the bottom.

After removing any lumps, they use a macle-brush to apply the composition to the walls and then wait 20 minutes. If there are still individual putty sections, make a copper sulfate solution, wet the GCL, and let it sit for ten to fifteen minutes. Following this process, you can use large-grain sandpaper to thoroughly clean the walls.

From a tree

Wood is cleaned of old putty, mostly mechanically. Electrical tools work best for this kind of work. You can even use a standard electric drill with a flat nozzle. If that is not possible, it is advised to buy a wood wash; these are available at any building supply store. After brushing shuttings onto the surface, the putty softens for the duration of the temporary period specified in the instructions.

Conventional hand tools can easily remove it as it soaks into the material. The most important thing is to move slowly and deliberately to avoid damaging the foundation. It is preferable to begin work in the trickiest, hardest-to-reach locations before moving on to more accessible ones.

Method Description
Scraping Use a putty knife or scraper to carefully remove the putty from the surface. Be gentle to avoid damaging the wall or ceiling.
Sanding Use sandpaper or a sanding block to smooth out and remove the putty. This method is effective for small areas.
Heat Gun Apply heat with a heat gun to soften the putty, making it easier to scrape off. Be cautious with the heat to prevent surface damage.
Chemical Remover Apply a paint or putty remover according to the manufacturer"s instructions. This helps dissolve the putty for easier removal.
Water and Sponge For water-based putty, dampen the area with water and use a sponge to scrub the putty off. This method works well for fresh putty.

Putty removal from walls and ceilings can appear difficult, but it can be done with the correct method. Be it priming a surface for painting or repairing flaws, it’s critical to understand the techniques at your disposal. Every technique has a distinct set of benefits that address various requirements and situations.

For large areas and thick putty layers, mechanical techniques like sanders and scrapers work well. Even though they need physical labor, they work quickly, especially when paired with power tools. Wearing protective gear is essential to protect against dust and debris.

For intricate tasks or situations where using mechanical methods could cause surface damage, chemical removers offer a less labor-intensive alternative. By softening the putty, these solutions facilitate its removal with a scrape. But whenever you handle chemicals, make sure there is enough ventilation and always abide by the safety regulations.

Another option is heat guns, which work especially well with old, hard putty. The material can be peeled away because of the heat’s softening effect. Although this method works well, it must be used carefully to prevent damaging the underlying surface or creating fire hazards.

Depending on the circumstances, each of these techniques can be useful alone or in combination. Evaluate your putty removal needs, the state of your walls and ceilings, and your comfort level with each technique. With the correct technique, you can get a clean, smooth surface that is ready for the next treatment.

Recall that preparation and patience are essential. Assemble your equipment carefully, become familiar with the procedure, and proceed methodically. These techniques will help you remove putty and get your walls and ceilings ready for a beautiful finish.
