Q. What does pH mean?

A. pH stands for the presence of Hydrogen. It is a scale from 1-14 that indicates how acidic or alkaline a material is. A pH of 7 is neutral, materials with lower pH’s are acidic and higher are alkaline. Materials with very low ( <4) or very high (>10 ) pH’s can present serious personal health risks like causing chemical burns, that require appropriate safety equipment such as gloves, glasses, goggles or face shield and chemical resistant clothing.

Q. What does the solids content of a floor finish really mean?

A. The solids content of a floor finish represents the amount of material that is left behind to protect your floor, after all of the water or solvent that it is carried in evaporates away. For example, a finish with a solids content of 25% will dry to film thickness which is 1/4 of the wet film applied. 

A good “rule of thumb” to use when applying any finish is that “it comes out of the bottle white, but spread it until it is just turned clear“.

Q. Are higher solids content floor finishes better than lower solids content finishes?

Short Answer:  It depends.

Although the solids content does play a role in performance, the determining factor is actually the quality of what the solids are made of.

A finish made from cheap raw materials will perform poorly no matter how high a solids content it has.

A finish made from quality raw materials will perform better and be less expensive to use, because it will last longer and be easier to maintain.

Q. What is the difference between a regular and no-rinse floor finish stripper/remover?

A. Regular floor finish strippers which often display a corrosive label are made from powdered ingredients such as Sodium or Potassium Hydroxide, Sodium Meta-silicate that can leave an alkaline (high pH) residue that can negatively affect the performance of floor finishes, unless they are removed by rinsing the floor. No rinse strippers are generally made from water soluble solvents or other materials that evaporate without leaving a residue, so they don’t usually negatively affect floor finish applications.

Q. Should I use hot or cold water when diluting my floor finish stripper?

A. With modern floor finish strippers usually cold water is preferable. With no rinse strippers it is required because hot water will cause the active ingredients to evaporate out of the solution rendering them ineffective.

Q. What do the different dilution ratios on cleaner labels mean?

A. Dilution ratios are guidelines for how much of a cleaner to mix with water to perform a particular task. Dilution ratios are usually presented in one of two ways, a ratio of parts (1:64) which can be any unit of measure, or specific units of measure like ounces per gallon (2 ounces/gallon.).

To convert a ratio to a specific unit of measure simply requires knowledge of that unit and simply division. For example, to convert the ratio 1:64 to ounces per gallon, you need to know that there are 128 ounces in a gallon and then divide 128 by 64 = 2 ounces per gallon.

Q. What are fisheyes and what causes them in floor finishes?

Short answer: It depends.

While it can be an indicator of an incompatibility between products (like a stripper and finish), it is generally indicative of a problem with application – like insufficient rinsing before coating, or not allowing sufficient drying time where VOC gasses from a stripper are still escaping from the vinyl tile substrate.
