The amount of stain needed to cover a 900 sq ft deck typically depends on the type of stain and the surface's porosity. On average, one gallon of stain covers about 200 to 300 sq ft. Therefore, for a 900 sq ft deck, you would likely need 3 to 4.5 gallons of stain, so purchasing 4 to 5 gallons is advisable to ensure full coverage. Always check the manufacturer's instructions for the specific product you are using.

Yogurt contains mostly lactic acid bacteria, which are Gram-positive bacteria. This means they will stain purple under a Gram stain.

By which type of stain colors it.
If iodine is not applied, both the gram-positive and gram-negative stains will appear to be gram-negative. The iodine acts as a mordant that helps to fix the crystal violet stain in the gram-positive bacteria, making them appear purple. Without iodine, the crystal violet stain can be easily washed out of both gram-positive and gram-negative bacteria, resulting in a pink or red color.
A negative result for a spore stain indicates that the organism does not form endospores. Endospore formation is a survival mechanism for some bacteria to withstand harsh environments, so a negative result suggests that the organism may be more susceptible to environmental stressors.
Bacteria stain either gram-positive or gram-negative based on the presence or absence of a cell wall. Viruses do not pick up a gram stain.
Bacteria are gram positive or gram negative. Serratia happens to be a gram negative bacteria. They appear pink on a gram stain. Gram positive bacteria stain to a purple color on a gram stain. We can classify and ID bacteria using their gram stain and shape. Some antibiotics only work on gram negative bacteria and some only work on gram positive bacteria. It helps a doctor know which antibiotic to use.
