Abstract
Background
This project was included in Lonny Grafman's Practivistas summer program through Humboldt State University HSU. It took place from May 22-July 4, 2015 in the small community, Las Malvinas, located in the outskirts of Santo Domingo, Dominican Republic. The task at hand was to finish the botica popular, which was built in summer, 2013, by other Practivista students Las Malvinas botica popular hullkrete 2013. Working with the community, seven Practivistas students designed and implemented this project based on the current criteria at hand. The project team was composed of a group of six students studying at Humboldt State University, all members of Lonny Grafman's Practivistas program. The project entailed making and applying plaster to the botica, laying out a floor for it, and providing materials needed for the electric plan of the building.
Objective
The objective of this project is to complete the botica popular in Las Malvinas in a way that best fits the criteria discussed, while hopefully providing the community with a finished product of what will become a reliable source of much needed medicine.

How To
Apply Plaster
Below is a table describing a common method for plastering a wall. This table is built on the assumption that one has already gathered materials/supplies and have already made the plaster being used. Also note that there are many different methods of applying plaster to a wall; the following table describes one of these ways.
How to Plaster a Wall | |||||
---|---|---|---|---|---|
Steps | Instructions | Instrucciones | |||
Step 1 | Level Wall. This is done often in doorways and the tops of walls so that the applied plaster will be evenly distributed along the wall of interest's perimeter. | Ponga Nivel. Esto se hace en las puertas y arriba de las paredes para que el yeso aplicado será distribuido nivelado en el perímetro de la pared. | |||
Step 2 | Use the trowel to mix the water in with the plaster to ensure the correct consistency; Use the trowel to lift some of the plaster and drop it. Do this three times until you have a smooth consistency. | Usa la plana para mezclar el yeso para saber la consistencia correcta. Usa la plana para levantar unos del yeso y deja caer. Hágalo tres veces hasta que tienes una consistencia suave. | |||
Step 3 | Water down wall. This can be done easily by poking a hole through the cap of a water bottle and then spraying the wall. | Ponga agua en la pared. Esto puede hacerse pinchándola un aguajero a través del tapón de una botella de agua y luego rociar la pared. | |||
Step 4 | Use the trowel to lift some of the plaster and drop it. Do this three times until you have a smooth consistency, now scoop some plaster onto the backside of a trowel and place against wall at an upward, acute angle so that the plaster is in between the wall and the trowel. Apply pressure while pressing upward (sometimes at a diagonal direction) along the wall. Plaster should stick well to the wall. | Usa la plana para levantar alguno del yeso y después, bajalo. Hace este tres veces hasta tiene una consistencia suave, ahora ponga algunos del yeso en la parte posterior de la plana y póngalo en la pared en una ascendente ángulo agudo para que el yeso está entre de la pared y la plana. Aplica presión mientras se presiona hacia arriba (a veces en una dirección diagonal) a lo largo de la pared. Yeso debe pegarse a la pared. | |||
Step 5 | Smooth out small areas of plaster on the wall with a flat/rectangular trowel to give the plastered part a smoother/cleaner look and then repeat this and Step 4 until the entire wall is covered in a layer of plaster. | Suavizar las áreas pequeñas del yeso en la pared con la llana para dar a la parte enyesada una mirada más lisa y luego repita esto y el paso 4 hasta que la pared entera sea cubierta en una capa de yeso. | |||
Step 6 | When the wall is covered in plaster, let it dry a little bit for approximately 20 minutes. Less, the wall might be a little too wet for the next step; but more time, the wall will be too dry, making the next step difficult to tackle. | Cuando la pared está recubierta de yeso, déjele secar un poquito durante aproximadamente 20 minutos. La pared ppuede ser un poco demasiado mojada para el siguiente paso; con más tiempo, la pared será demasiado seca que hace el siguiente paso difícil para hacer. | |||
Step 7 | Smoothing time for the wall. When smoothing, the wall must be wet to use the wood float, but it's much easier to use a sponge to both wet, and smooth the wall. Using this method, push a wet sponge against the wall in circular motion. Little pressure is needed, but it depends upon how wet the sponge is (more pressure if less wet). The plaster should look blended together and well-distributed, giving the entire wall a smoother/leveled look. During this step, the plasterer must look out for uneven indents or spots on the wall and fill them using Step 4 and 5, if needed. The entire wall needs to be evened and mixed using this sponge method. | Tiempo del allanamiento para la pared. Cuando alisa, la pared debe ser mojada para usar la flota, pero es mucho más fácil usar una esponja para mojar y alisar. Usando este método, empuje una esponja mojada o húmedo contra la pared en el movimiento circular. Poca presión es necesaria, pero depende de qué mojado la esponja es (más presión si menos mojada). El yeso debería parecer mezclado juntos y bien distribuido, dando a la pared entera una mirada más lisa/nivelada. Durante este paso, el yesero debe buscar para marcas y llenarlos con el paso 4 y 5, si es necesario. Toda la pared debe ser nivelado y se mezclado con este método de esponja. | |||
Step 8 | When the plaster is dry, the wood levels can be taken down, and the wall can then be admired for eternity. | Cuando el yeso es seco, la estructura de madera pueden ser bajados, y la pared puede ser admirada entonces por la eternidad. |
How To
Plaster Test
The following table describes the two main tests performed on a dry, plastered wall. These tests will determine whether the plaster will be sufficient in providing enough strength and resilience to use on the wall.
How to Perform a Plaster Test | |||||
---|---|---|---|---|---|
Steps | Instructions | Instrucciones | |||
Step 1 | The first of two tests performed for checking if the plaster used is sufficient, is called the "water test". Using a water bottle with a hole in it's cap or side is most useful. Stand in front of the wall and apply pressure to the water bottle so that it is hitting the same place on the plastered wall for about 60 seconds. The duration and distance from the wall are dependent upon the pressure of the water source. The most important thing is to keep these parameters consistent between tests, in order to make meaningful comparisons. If there is no significant indent made in the plaster, the plaster passed the water test. If the water burrows a hole in the plaster, the size of the indentations can be compared. | La primera de dos pruebas funcionó para comprobar si el yeso usado es suficiente, es llamado la "prueba de agua". Usando una botella de agua o refresca con un agujero en la tapa o en el lado es el más útil. De pie frente de la pared aplica la presión en la botella (de agua o refresca) de modo que golpee el mismo lugar en la pared enyesada durante aproximadamente 60 segundos. La duración y la distancia de la pared son dependientes de la presión del agua. Lo más importante es mantener estos parámetros consistentes entre las pruebas, con el fin de hacer comparaciones significativas. Si no hay marca significativa hecho en el yeso, el yeso pasó la prueba de agua. Si el agua penetra un agujero en el yeso, se puede comparar el tamaño de los agujeros. | |||
Step 2 | For the scratch test, the second test performed, one must use a metal brush to apply a consistent pressure on the wall while pressing up and down 100 times. If this creates an indent or hole in the plaster, then the plaster used will not pass this test. As with the water test, the degree of failure can be compared to determine the most promising recipes to iterate upon. | Para la prueba de raya, la segunda prueba funcionó se debe utilizar un cepillo metálico para aplicar una presión constante en la pared mientras presiona hacia arriba y hacia abajo 100 veces. Si esto crea una marca o agujero en el yeso, entonces el yeso usado no pasará esta prueba. Como con la prueba del agua, el grado de insuficiencia puede compararse para determinar las recetas más prometedores para iterar sobre. | |||
Step 2 | Scratched the wall 100 times with the wire brush. Almost all of the plaster came off. | Rayado la pared 100 veces con el cepillo de alambre. Casi todo del yeso se cayó. |

Operation
This is how to operate. It should have a brief introduction and very useful images with labels. Also it may work best for your project to use the step by step how to template {{How to}}. See #Troubleshooting for an example.
Maintenance
Maintenance for the botica is fairly straight-forward. Since this building is so significant in the community, giving them access to cheap medicine locally, the utmost care must be given to the building. The building should be monitored for leaks on a consistent and normal basis... especially since the inner wall is covered in natural plaster, which didn't pass both plaster tests, so if exposed to weather, it can be degraded. Taking care of locking up the door at night and not letting children come play inside of the building can extend the life of its features as well.

Discussion
Both types of sand performed well when the recipe included secante and excluded a fiber. However, none of the recipes passed the water test adequately for outdoor use. It was decided that the fine sand recipe would be used for the indoor plastering, and a cement recipe would be used for the outside work.
