3. Cut off the sealant seal, install the glue nozzle, and put it into the glue gun;
4. Apply the sealant evenly on the joints, the thinnest part is greater than 1mm; when using the pneumatic gun, the air pressure is controlled at 0.3~0.5Mpa;
5. The product can be colored by traditional methods after surface drying, including epoxy resin and acrylic paint.


Matters Needing Attention
1. Avoid construction under 5℃ and humidity less than 20%
2. Pneumatic pressure is strictly prohibited to exceed 0.5 Mpa, if it exceeds 0.5 Mpa, gas will enter the hard packaging tube, and colloidal bubbles will occur.
3. Because the coating contains high solvent content, the glue surface will become soft. In order to obtain the best appearance and performance, the glue should be colored after curing for 24 hours.
