The basis of high–quality repairs is smooth and smooth walls. When leveling them with plaster, you can not do without a building rule. In Harbor Freight Ad Kentucky, we will look at what types of this tool exist and the technique of working with them.
By its design, it is a rigid metal or wooden rail up to 3 m long with a sharp edge.
The applied plaster layer is leveled with a rule, excess mortar is removed, the correctness of the installation of lighthouses and the flatness of the surface are checked. This tool can be used as a ruler in the process of marking walls. It allows you to determine the differences and deviations from the level and perform high-quality plastering of the surface for subsequent putty.
aluminum – modern and high-quality tools are made of light metal. They have a low weight, which is important for large volumes of work. But aluminum does not provide durability, and when working with plaster (especially with cement-sand mortars), the edge of the rule wears off over time. Irregularities and scratches form on it, which worsen the quality of plastering;
There are tools of various sizes on sale. The usability of the rule is affected by its length, which must be chosen depending on the width of the wall and the distance between the guiding beacons.
The rule should fall on two lighthouses and go beyond them by 10-20 cm. This is necessary in order to pull the tool not only up, but also left and right when leveling the plaster.
Manufacturers offer a standard size range of finished products from 1 to 3 meters in increments of 50 cm.
Long rules are convenient to use when working in pairs, which speeds up the process of plastering the wall. The tool with the largest size checks the diagonal of the plastered wall and reveals hidden defects.
Any plaster tool can be truncated, i.e. cut off in the right place to fit the width of the wall.
Types of forms
Manufacturers offer 3 forms of rules. They differ in functionality and ease of use.
Tools with an h-shaped cross-section are convenient for distributing plaster on the wall, leveling along lighthouses. the h-shaped shelf serves for a convenient grip of the tool with your hands. If necessary, a level can be placed on it, with the help of which surface errors are detected.
The advantages of this type of products include:
- good bending stiffness;
- a wide working surface on which a lot of mortar is placed;
- easy to clean – the prepared mixture is easily cleaned off with a spatula from the surface of the sole of the tool and can be applied to the wall again.
The main disadvantage of this model is its high cost.
This kind of rules is used for trimming plaster. They work perpendicular to the wall, remove a small amount of gripped mortar.
Along the surface on many models there is a chute for easy grip. On both sides, the rule is closed with removable plugs. When choosing this tool, it is necessary to pay attention to the presence of reinforcing elements inside the structure, which come in the form of struts or tubes.
Wedge-shaped samples have a number of advantages:
- lightness – due to the hollow structure, it has less weight compared to analogues;
- the difference in price is much cheaper than samples of other models.
The disadvantages include:
- insufficient bending stiffness (especially for cheap models without reinforcement inside);
- inconvenience when stretching the solution.
This model has all the advantages of the above product variants and is practically devoid of disadvantages due to design features.
In shape, it is an h-shaped rule with a trapezoidal working side. A versatile tool that combines the advantages of both of the above forms and has excellent rigidity.
A tool with this shape is not very common, and finding it in hardware stores is a great success. On the other hand, the price of such a rule is higher than the usual one.
How to use it
You can align the plaster on the walls with or without lighthouses. With the help of these devices, control over the evenness and smoothness of the future surface is ensured.
The solution is leveled by lifting the h-shaped rule from the bottom up. The excess mixture accumulated on the sole of the tool is removed with a spatula and thrown onto the wall in unfilled places. The resulting irregularities, sinks and voids are filled with mortar and stretched again until the wall becomes smooth.
After completion of this stage of work, the beacons are removed from the plaster, the cracks are sealed with mortar.
Two hours later, after the surface of the wall “grabs”, they begin to trim the excess with a trapezoidal rule.
How to make with your own hands
Simle way to buy at Harbor Freight Ad Kentucky. But… If the evenness of the walls is not important, then you can distribute and pull the solution with any board or bar, sharpening and polishing the working edge of the product.
But homemade rules will not be able to compete with factory ones in terms of the quality of plastering, so you should not waste your time making them if you want perfect walls.
