It should be recognized by the user that not all sealants meeting this specification are suitable for all applications and all substrates.
The sealant shall be composed of latex formulated with appropriate fillers, pigments, and chemical additives. Every manufacturer of quality products tests their products and labels the caulk tubes accordingly.
The following are the type and grade of sealant under this specification: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Is it an inside or outside application? PaintPRO Archives pg 1 of 2. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Sealant types Generally, caulks and sealants are members of one of the following types of chemical families. Silicones are also reactive-curing compounds, but they offer easy gunning ability. Sealants used in commercial construction may be specified by the owner, architect or engineer; however, the contractor often has final say on brand and type.
The physical properties of the sealant shall conform to the specified requirements according to x834 and grade.
Because they are hard to remove completely, especially on porous surfaces, repairs and future painting can be difficult.

Typically, the higher the cost, the greater the performance you can expect.
asttm These are the most common in the paint industry and come in a variety of formulations that affect cost, durability and adhesion. Sealant selection is very much performance-based. They are low in cost and come in a wide range of performance grades.
New silicone may not stick to old silicone, so proper surface preparation is the key to successful sealant repairs where silicones have been used. Some must be applied to a primed surface, but in general they adhere well to a variety of surfaces.
Many are available in colors to match substrate, eliminating the need for painting. The inch-pound in parenthesis are provided for information purposes only. Even if the aztm degrades with heavy traffic, the compound will still maintain an effective seal. They maintain their properties over a wide temperature range. If tests are required using substrates in addition to or asgm than standard, they should be so specified for testing.
Sealants are tested to federal specifications or standards set by ASTM.
