Unfortunately, since creating this video, Sika has decided to discontinue this product. Due to the production difficulties they had during 2020 and 2021, this product had to be shelved. Every time I have the opportunity to meet with Sika higher-ups, I ask them to bring 1A Artic back. It was that good. I am hopeful that after the Master Builders acquisition is completed, they will find room in their production and market to reintroduce 1A Artic. But only time will tell. Until then, we still have 2C Artic, a fantastic product we will continue to utilize once the weather turns cold for the year.
Take a look at our overview video of SikaFlex 2C Arctic here. If you need to place urethane sealant in the cold, it is your best bet.
If you perform sealant work in the cold, take a moment to watch our video on Albion B-line Caulk Guns. This goes over the differences in thrust ratios on their caulk guns, and which are better for what materials and weather conditions.

Efflorescence is the gift that keeps on giving. Like pyrites to precast, efflorescence is an unsightly condition that can ruin the appearance of your masonry structure or even damage it to the point of repair. What causes efflorescence? A recent article published in July 2019 Masonry Magazine takes an in depth look at the issue at hand, the following is a excerpt from that article, the full article can be accessed by members of Mason Contractors Association of America.
Concrete surfaces form cracks; thermal changes and ground settlement are some of the common reasons why . This is inevitable with all types of concrete and concrete surfaces, ranging from smooth and split-face concrete block to poured-in-place, precast, and tilt-up walls.
Leaving existing joint sealant in place and installing an overlay of new sealant can be an option if the conditions allow. While this could be considered a cost saving technique, the majority of existing conditions would not be acceptable for this technique. While it would save the installer time, in addition to material, by not removing the existing sealant, it mostly results in improper joint design and extremely premature failing of system.
J.S. Goray Inc recently returned from a week long trip to Las Vegas for World of Concrete 2018. Six representatives from our firm were in attendance, including both field and management personnel.
THE SIGNIFICANCE OF THE INITIAL RATE OF ABSORPTION IN BRICK MASONRY WALLS
Masonry mortar must bond well to the masonry units in the wall. Brick absorption, including initial rate of absorption (IRA), is an important property affecting the bond. IRA also is a property for which a standard test method exists.
The pricing of building restoration work is more of an art than a science. An accurate estimate and proposal is critical to both the contractor and owner. Under bidding of projects will result in a very low Bid - Hit ratio. This would seem to work to the owners advantage but unfortunately the opposite result is more likely.
