Technology of plastering columns: types and device, description of the plastering process

Column plastering is a specialized task that calls for dexterity and meticulousness. Columns, which are typically regarded as decorative or structural components, can become magnificent features with the appropriate plastering methods. Whether you’re working with more contemporary, angular designs or traditional round columns, knowing the steps and materials required will help you achieve an impeccable finish.

There are different kinds of columns, and plastering each one has its own set of difficulties. The methods employed can differ greatly, from guaranteeing a smooth surface on cylindrical columns to managing sharp edges on square ones. However, even complex shapes can be mastered with the right tools and a methodical approach.

This post will discuss the various kinds of columns you may come across, the tools and supplies you’ll need, and the thorough plastering procedure. Regardless of your level of experience or desire for do-it-yourself projects, this guide will give you the knowledge and advice you need to confidently take on column plastering.

Construction, types of columns

Purlins and floor beams, which are made in a variety of shapes including round, polyhedral, tetrahedral, and elliptical, are features of extended architectural elements.

There are other comparable structures that have a nearly identical appearance in addition to pillars, or columns, which are typically used to distribute weight. These consist of pilaster posts and half-columns. A column’s top, base, and main trunk are always present.

The pillars are almost entirely composed of one section, which occasionally grows or shrinks in closer proximity to the ceiling for aesthetic reasons. The cylindrical concrete column of the classic design progressively gets smaller as it gets closer to the top.

Fascinating! Fluted columns are almost universal; their purpose is to visually shorten the column and lengthen the trunk. The first people to make them were the Egyptians.

Semicircle-shaped slots are found in fluted columns. They finish with a smooth groove and run the full length. The spaces in between them are level.

Rustication is another method of finishing columns; it simulates the appearance of stones running the length of the column. Brick, concrete, metal, and wood are used to make pillars.

How to plaster columns

The composition’s application and distribution technique is determined by the columns’ shape and the presence or absence of extra decorative elements. Also, they devise reasonably priced ways to use the product based on its design.

A particular method must be used when plastering columns to guarantee their long-term strength and visual appeal. This post will walk you through the various kinds of columns, the supplies needed, and a detailed explanation of the plastering procedure. These techniques will help you create polished, silky columns that improve any room’s overall look.

Preliminary hanging

Hanging is used for plastering geometric-shaped columns. Processing these forms calls for extreme precision because any leakage will show up right away. The beginning of hanging out on the street is any extreme column. It is carried out in phases:

1. A self-tapping screw is placed at the top and a hole the size of a layer of plaster is made in its head.
2. A plumb line is lowered through it.
3. At the bottom, the second screw is fixed so that the head touches the thread.
4. It is tied tightly and several more elements are placed along the length to align the column.
5. The same tension is performed on the other extreme column, and on all intermediate structures, screws are placed, focusing on the auxiliary area.

Crucial! Only when the auxiliary plane is parallel to the wall can something be correctly hung.

Stamp device

They are created by applying a gypsum solution along the thread. The top is severed so that it faces the plumb line. To make the piles look tidy, it is also taken off of the sides. Marks are also used to fill the beacon on round columns once the template has been fixed.

Installing lines around the perimeter of the structure is necessary for plastering a round pillar. Move one to one and a half meters apart.

A solution the size of your palm is applied to the column to create a stamp, and the top is then cut off along a vertical thread. The mixture is applied closer to the ribs in square columns because they require a more precise installation of the rule.

Columns with a curved contour

In order to plaster non-standard shaped round columns, start by inserting a self-tapping screw at the bottom, where the largest radius is located. The plaster layer’s thickness determines how the cap is adjusted. Subsequently, a small weight is affixed to the top in order to allow the thread to reach the lower screw. The second element is positioned there after the difference that results is measured from the upper suspension.

Beacons

Only round and semicircular columns and pilasters are appropriate for them. To fix them, a ring template that is installed across the column is needed. The shield, on which the column’s circumference is drawn, serves as the template. After that, two semicircles are cut out and it is sawed. After that, the building is joined, and mortar beacons are mounted on a ring.

Crucial! Because the diameter of the column varies in different places, multiple ring templates may be needed in certain plastering situations.

Plastering process

Depending on the column’s contour or shape, different composition application technologies are used.

Round

Making a template in advance, keeping an eye on the vertical in two directions, and carefully grouting are all required steps before plastering the column. You can skip creating a process map for this, as all you need to do is hang the structure, add markers and beacons, and remove the base. After the rule is applied and the excess is eliminated, the solution is tossed in between the installed guides.

Plastering involves first processing half of the column, then finishing the remaining portion and installing the strobe. In order to make the layer monolithic, everything is done at once.

Tetrahedral

The elements of tetrahedral columns are fixed to the front and rear planes of the extreme structures when they are suspended. The mortar’s thickness is determined by pulling the cord through the entire row. The lower and intermediate marks are then set, and the plumb lines are fixed. Beacons are affixed to the columns and mortar is applied once the plaster’s thickness has been determined.

Multifaceted

Here, a template is created beforehand, but each face is worked with independently. Every face is measured first, and then the beacons are set and hung.

Crucial! Multiple layers of processing are applied to multi- and tetrahedral columns while keeping an eye on the central axis and guides.

With a curvilinear contour

Plastering entasis columns involves following a number of guidelines and beacons. For the cylinder, a rectilinear rule is used, and for the tapering portion, a template. Immediately after, the entire column is covered with plaster, and it is leveled.

Finishing flutes

The hardest slots on a column to process are the longitudinal ones. Experience is required for this, particularly in calculating the running meter and determining how to apply the material evenly beforehand.

Tetrahedral

Working with a rectangular and tetrahedral cut is simpler. To do this, a template with slots that replicate the holes’ shape is used.

Multifaceted

It is done in the same manner as if you were making grooves in rectangular columns. Even when applying decorative plaster, the template is utilized.

Round

A manual metal template is made for round columns. In workshops, the template is occasionally ordered separately because appropriate tools aren’t always available.

Is plastering possible without a template

Plastering round structures with regular and decorative textures is appropriate without a template. The composition is applied in layers subsequent to the installation of beacons. After leveling it with a rule, it is led in a zigzag pattern.

Type of Plaster	Description and Process
Cement Plaster	Mix cement, sand, and water. Apply a rough coat for grip. After drying, add a smooth finishing layer.
Lime Plaster	Combine lime, sand, and water. Apply a thin coat, then smooth with a trowel for an even finish.
Gypsum Plaster	Mix gypsum powder with water. Apply in thin layers, allowing each to dry before adding the next.

A specialized skill that can significantly improve the durability and appearance of these architectural elements is plastering columns. A smooth and polished finish is ensured by knowing the various types of columns and the unique techniques for each. To get the best results, whether you’re working with round, rectangular, or square columns, the proper application and preparation techniques are essential.

Although the plastering process for columns is similar to that for walls, it still requires close attention to the particular shape and surface of each column. Maintaining the integrity of the column’s design can be achieved by properly fastening the base, applying the plaster in thin, even layers, and smoothing out any imperfections.

Plasting even intricate column designs can be accomplished with ease if the correct equipment, supplies, and time are available. By using these methods, you can make sure that your columns enhance the overall aesthetics of your area and not only look fantastic but also endure over time.
