- Features
- Watertite JS is a specially designed formulation for use with concrete and steel expansion joints, up to maximum of 3 ½ (8.9 cm) in width. The adhesion to concrete and steel is chemical, ensuring a permanent bond. Rain, snow or water will not effect the sealant. Pot life and curing time may be adjusted to suit any particular job situation without changing or affecting the physical properties and performance of the cured sealant. Watertite JS offers many advantages.
- The sealant keeps water and moisture out indefinitely. Being a liquid when applied, it finds its own level and thereby fills small cracks and imperfections, giving a perfect seamless seal and bond to all surfaces. Because of its excellent adhesive properties, moisture will not be able to penetrate the seal.
Applications & Uses
- Markets
- Applications
- Uses
Watertite JS is used for treatment of joints and cracks in new or existing structures.
- Design Limitations
Watertite JS is not to be applied to surfaces that are either wet, oily, frosted, dirty or contaminated in any way. Watertite Surface Conditioner should be used on all surfaces. The depth of the sealant in the joint should never be greater than the width of the joint. Preferably, the depth should equal ½ of the width. NOTE: Consult PennKote Limited for specific data on applications not detailed in this literature.
- Applications
- The two pre-measured portions should be thoroughly mixed by means of a double bladed agitator attached to a low speed electric drill. Mix the material for a period of not less than eight minutes.
- Improper mixing will not allow material to cure properly. Watertite JS may be applied either by pouring or caulking gun at temperatures as low as –18oC (0o F). The quality of the sealant is not changed by freezing temperatures. In order to obtain the best mixing and application results, Watertite JS should be used or mixed at approximately 16oC (60o F), whenever possible.
- A power brush and compressed air should be used for cleaning joints or cracks. Use a gas torch to dry out any wet surfaces. For expansion joint backup install a closed cell PE foam, or other suitable supporting material.
