How do I apply the PUR adhesive on concrete properly? The first thing to do is clean the concrete surface thoroughly. It should be free from dust, dirt, grime and grease. The surface should also be dry.
For the best results, apply the adhesive onto the concrete when the temperature is between 65?°F and 95?°F. If the concrete is too hot or too cold, the adhesive will not be as efficient.
Read and follow the adhesive manufacturer’s instructions carefully to make sure that you get the best bond between your two surfaces. Then apply the adhesive evenly onto one surface only, using a notched trowel.
Slowly and carefully bring your two surfaces together, clamping them in place if appropriate. If you have split any adhesive it is essential to remove it immediately with a damp cloth before it sets. Next (and this is almost the mort important step), leave the surfaces alone for at least 8 hours, preferably 24 hours. This will ensure that the adhesive on concrete has totally set.
How fast you want the bond to be created is quite an important determinant of the type of adhesive to purchase. The fastest bonding adhesives are superglue and hot glue. Water-based contact cement sets immediately and takes roughly half an hour to dry. White glue and carpenter’s glue take a number of hours to dry. You will however need to wait for a full day before a silicone based adhesive dries completely.
You can choose a suitable one from plenty of adhesive options to create bonds that need to be waterproof. Your choices include water-based contact cement, silicone based adhesives, two-part epoxies, or superglue. Most wood adhesives don’t take too well to even relatively low amounts of moisture.
In terms of heat resistance abilities the aforementioned types of adhesives will also be most effective.
Different adhesives offer varying degrees of cleaning ease, a factor that is dependent on their individual constitution.
Adhesives that can be easily cleaned up using water alone include wood glue and white glue, silicone sealers, and water-based contact cements.
Other adhesives require the use of a solvent like acetone to clean up. In this category we have non-water based silicone adhesives, two-part epoxies, and superglue.
