There are certain jobs that have to be done absolutely correctly in order to be successful. One of those is waterproofing. If sub-par workmanship or a faulty sealant is used, the seal could fail and lead to big problems. Many of our customers trust Sikaflex sealants to do the job quickly and effectively. Here’s a closer look at their polyurethane / elastomeric sealant.
- Where to use
Sikaflex-1a is just about any type of joint where the maximum depth of sealant isn’t more than 1/2-inch. That makes it ideal for windows, door frames, roofing details, and it can even be used as an adhesive strong enough for many construction applications. Sikaflex can even be applied in submerged conditions on a canal or reservoir.
- Why to use
There are a number of advantages offered by Sikaflex-1a. It’s among the most efficient products on the market, which means time, effort and equipment needed to mix, fill cartridges, pre-heat and clean is all minimized. The tack-free and final cure times are also fast to enable you to move on to the next task quickly. It’s suitable for even the toughest of climates and will stand up to aging and weathering and is even jet fuel resistant. Sikaflex also offers high elasticity and cut and tear resistance. As for adhesion, it’s able to bond to most materials without the need for a primer.
- When not to use
While Sikaflex has many advantages, it’s not the right choice for every application. The depth of sealant should fall between 1/4-inch and 1/2-inch. The expansion and contraction of the joint it’s applied to shouldn’t exceed 25-percent of the average width. While you are able to paint over Sikaflex after curing, compatibility and adhesion testing should be done with any type of oil and rubber based paints. Environments with high levels of chlorine are typically not conducive to the use of Sikaflex. In total water immersion environments, up to one week is required for the product to fully cure and be paintable.
- How to use
If Sikaflex is right for your project, start by preparing the surface area. The joint should be thoroughly cleaned and chemicals and other substances removed completely. A roughened surface will actually enhance adhesion so take necessary action before applying. Take care to use materials like bond breaker tape to prevent bond at the base of the joint and any other unwanted areas.
Priming is not typically necessary, except when the sealant will be submerged in water after cured.
Apply between the temperatures of 40-degrees and 100-degrees. Ideal application should occur when joint is at midpoint expansion.
