Gypsum putty can be properly prepared by following a few simple steps. Here are the detailed instructions:
1. First, pour water into a bucket, 1/3 of its capacity. Gradually, in a thin stream, add the powder to the water until the powder level exceeds the water level by 1/3.
2. After adding the powder, let the mixture stand for half a minute to allow the powder to settle into the water.
3. Then, using a special drill attachment, stir the solution for 1-2 minutes. It is important to carry out this process continuously and vigorously to achieve a homogeneous consistency. If the mixture seems too liquid or too thick, a small amount of water or powder can be added in the appropriate proportion, while continuing to stir the mortar throughout.
4. After completing the first step of kneading the mortar, leave it for a few minutes to allow the mixture to begin its reaction and acquire the desired consistency. Mixing the second time is carried out in the same way as the first time, again for 1-2 minutes.
5. It is important to check the viscosity of the mixture to make sure it has the right consistency. The ideal putty mixture should be viscous enough to adhere well to the wall when applied, but not remain on the trowel. If the mixture is too thick, you can add a small amount of water and mix well again.
6. It is important to note that when kneading the mixture, do not use high speeds on the power tool as this can introduce air into the mixture and create bubbles during application to the surface. Maintain a medium speed of immersion of the tool into the mixture.
By following these simple steps, you can properly prepare gypsum putty for a surface leveling job. It is important to keep an eye on the proportions and consistency of the mixture to achieve optimal results when applying it to the surface.
