Gross errors when mixing plaster

Errors in mixing the plaster mortar do not seem obvious in the process, but seriously affect the repair result. Incorrect mixing of the solution can in fact result in an unstable and cracked coating. In general, adherence to mixing technology will save time and money. So, the basic rules that do not comply.

We study the instruction

Read the instructions on the packaging of the mortar before the mortar is prepared. Carefully read the sequence of manipulations, prepare the necessary measuring containers or scales. Manufacturers write instructions briefly and readily.

Shelf life

Surprisingly, building bulk mixtures should be stored under certain conditions and for a very specific time. If one of the storage requirements is violated, then the plaster will not turn out homogeneous. And most likely will change the time of full seizure. Working with such a composition is extremely difficult, but the result is not predictable. The coating may begin to crack or peel off.

Pour the mixture into water

The preparation of any plaster occurs in the order of rash in small portions of dry matter into water. If you do the opposite, add water to the dry mixture, the solution will turn out to be heterogeneous, of different density, with lumps. These lumps of the mixture will prevent smoothing the surface. At a minimum, you have to impose an additional layer of putty to get a flat surface.

Do not add

In order to adjust the density of the solution, you can enter only water. Therefore, see paragraph one and study the instructions, understanding the proportions of kneading. If you introduce a dry mixture into an already prepared solution, the composition will not only be heterogeneous, it will have different setting times. It is difficult to work with such a solution, and the result will be of poor quality. In order not to miss the water, experts recommend taking a little less than the required amount at the beginning of mixing.

Do not mix different types

From the previous repair, only a few mixtures remained. They can be developed, but separately. Do not pour the mixture together. Most likely they will have different setting times, and the components may even conflict with each other.
