Finishing putty “Sheetrock”: properties and applications in construction

Production-blended Sheetrock putties are ready-to-use. The use of such mixtures saves time, eliminates defects, and minimizes the risk of waste. You don’t need water for mixing. You can simply open the bucket and start the filler process. This article will tell you about the characteristics and use of Sheetrock putty for finishing in construction..


For fast and high-quality work with drywall, it is recommended to use only first-class finishing materials, use auxiliary tools from trusted companies and additional accessories. Combining all of these factors increases productivity and improves the bottom line. One such product is Sheetrock putty..

The advantages of such solutions are obvious:

  • improved technical characteristics;
  • increased operational life;
  • homogeneity and uniformity controlled in each batch;
  • prolonged use (compared to self-prepared fillers).

The product is available in packs of 28 and 17 liters. You can rest assured of the quality of the composition, since it goes through 10 freezing / thawing phases during experimental tests and does not lose its properties at all.

If Sheetrock is exposed to frost, try to thaw gradually. Never use hot water and heaters for heating. Let the mixture stand indoors at room temperature.. Then stir the product until a homogeneous mass is obtained, simultaneously getting rid of air bubbles.

Preparation for work

Stir the contents of the container, you do not need to add water. Apply solution to corner protectors, fastener heads. For sealing joints with construction tape, it is allowed to add a small amount of water (it varies from 50 to 60 ml).

In this case, you need to ensure that the solution is not too liquid..

Terms of Use

There are several basic rules for using Sheetrock Superfinish Putty..

  • The tool is intended only for internal work.
  • A new application of the putty is carried out only on a completely dried previous layer..
  • The putty is sanded with 240 grit sandpaper.
  • To successfully paint and apply decorative finishes, you must strictly follow the manufacturer’s instructions. In order for the paint to lay down well, the coating must be dry, dust-free, matte, and should not stick to hands..
  • The application of a thin leveling layer of putty to the drywall sheet helps to level the water absorption of the material. In the future, this will help to avoid stains on the treated surface..
  • Don’t overdo it when dry sanding. Do not process the top of drywall and putty tape. Used in conjunction with Sheetrock putty, paper tapes, metallized liner tapes and protective corners.

Features of paper tape:

  • makes the structure uniform, strong;
  • has a fold in the middle for easy handling;
  • does not need the use of adhesives;
  • has good strength indicators;

Purpose of metallized paper tape:

  • strengthening of corners;
  • reinforcement of structures when installing drywall.

Features of Paper Backed Metal Corner Guard (Corrosion Resistant Steel Busbars Paper Backed):

  • gives strength to the corners;
  • does not need additional fasteners;
  • adhesion of the finished composition to the paper base is higher, which ensures ideal surface smoothness.

Drywall seams

The heads of the fasteners (self-tapping screws, screws) should be sunk into the surface of the drywall so that they do not protrude. To do this, you need a screwdriver or screwdriver. Then apply a continuous layer of Sheetrock with a stainless trowel, filling the joint between the drywall sheets. Slightly sink the paper tape into the filler layer. While tilting the spatula, slide it over the tape. Press down firmly on the tool to release the excess solution.

A putty layer of about 1 mm should remain under the construction tape. Then another coat of the mixture should be applied to prepare the substrate for the next finishing step and to protect the tape from edge curling. Wait for the joint to dry completely.

After the entire surface has got rid of moisture, you can proceed to the next stage of puttying. Take a wide spatula (about 20 centimeters) and start the second step of application.

When everything is dry, “walk” with the trowel again to form the finishing layer. This time, use a 25 centimeter tool.

Corner processing

To process the elements, the mixture is applied to both sides of the corner. The Sheetrock tape is folded in half and applied to the mortar. Apply a thin layer of putty on one side of the corner, wait until it is completely dry and apply the same layer on the other side. Tape first one, then the other side of the corner, removing the excess with a spatula.

Machining fixing screws or screws

Apply the finished undiluted mixture to drywall before and after gluing the joint with paper tape. Fill the grooves that formed in the places where the screws are fastened with the ready-made solution. Run the putty tool over the places where the screws are screwed in with pressure to level the layer of putty and drywall sheet. This process should be repeated several times until the grooves are flush with the surface to be treated. Multiple coats may be required.

Application to paper corners

Construction professionals strongly advise not to mix ready-made putties with water. The consistency should be the same as the manufacturer intended, otherwise the technological process will be disrupted.

Work the edges of the corner with Sheetrock with a medium trowel (about 12 centimeters). Wait until dry. The next application should be about 5 cm wider in width.And only at the end of the work, in order for the finishing layer to be smooth, you can add a little liquid to the putty.

Using protective corners made of metal on a paper base

Paper-backed corners have the same function as conventional metal busbars or PVC corners. But they are used when the connecting tapes are glued, and not when the drywall is being installed to the base. Their plus is that the paper base in any case has better adhesion characteristics than the usual metal one. Such a corner creates a stronger and more homogeneous structure, increases the resistance to cracking, which can occur as a result of natural shrinkage of residential buildings and industrial premises..

The difference between these corners and conventional metal and vinyl corners is that the Sheetrock corners are glued with putty, and the normal corners are simply put on. Paper-backed corners ensure that subsequent layers of putty, decorative plaster and other materials have good layer-by-layer adhesion. The corner is pressed into the putty layer, after drying it is putty.

Finishing stage of finishing

After applying the finishing layer, you must wait until all the applied putty layers are dry. Then you need to smooth out the “bumps” with a spatula so that the surface becomes even. The rest of the mortar is applied to the seams and fasteners. At this stage, a slight addition of water to the mixture is allowed. The applied layers must be well leveled. This will shorten the surface treatment time with a sanding float. It is also worth “walking” with putty on all noticeable defects.

Ready putty mixtures are an ideal option for preparing gypsum plasterboards for further painting.. When applying glossy paints, all irregularities and depressions can be visible on the wall. The use of Sheetrock finishing putty eliminates the possibility of such situations..


It is important to be careful when sanding the seams. It is not recommended to grab the surface of the drywall sheet, only the seams need to be sanded. The grater peels off the surface of the gypsum board, and paper fibers can ruin the finish..

It is recommended to apply a finishing coat over the entire surface to be treated in order to minimize the appearance of defects..


Users confirm that Sheetrock ready-mixed mortars are versatile helpers in finishing work. Reviews about the quality and usability of the mixtures are mostly positive. At the same time, many consider the correct determination of material consumption per 1 m2 to be the main condition for a successful purchase..
