SuperChink is Vimasco’s premium chinking material designed to fill and seal the spaces between the logs of a log home. It is formulated with a pure acrylic latex and is formulated to provide the highest possible quality in all regards, providing a high degree of durability, flexibility, resistance to mechanical damage, and resistance to cracking caused by log movement or shrinkage. This product is particularly recommended on applications involving gaps which are very wide or very deep, or where it might be exposed to very low temperatures for extended periods. SuperChink will maintain its integrity for many years even when exposed to a wide range of environmental conditions. SuperChink has a creamy consistency that makes it very easy to apply with no thinning or pre-mixing needed. It provides a tight seal between the logs and also provides a decorative textured appearance which looks good with just about any log home design.
SuperChink is a water-based emulsion that is completely safe and nonflammable. Because it is an acrylic it applies very smoothly and easily. It can be used in a gap of any size, but when being applied at more than 1/2” wet thickness it should be done in more than one application to minimize sagging and to facilitate better drying of the product. SuperChink should normally be applied over backer rod to eliminate an air space behind the chinking which can create some problems. Also, in applications where it is appropriate, a “bond breaker” tape should be used underneath the chinking. It can also be applied directly over wood or most other building materials. It is good for exterior or interior use.
SuperChink will maintain a soft and slightly pliable nature after it has cured so it never becomes completely hard or rigid to the touch. It may take several weeks for the product to dry completely, but is normally dry to the touch within 24 hours. It should not be subjected to rain or to freezing temperatures until it has dried for at least this long, and possibly longer depending upon the temperature and humidity at the time. The applicator should observe the drying speed of the SuperChink in relation to the ambient conditions and protect the product with plastic or heat as needed if it has not cured adequately. Once it has cured, though, it becomes virtually impervious to weather conditions.
