Works in Wet Conditions: Unlike many other sealants and adhesives, CT1 can be applied even in damp or underwater conditions. These prices were taken from the CT1 official online shop shop.ct1.com and the Adiseal official online shop https://guglue.com on 05/10/23. Yes, CT1 can be painted over once it has fully cured. It’s important to allow the sealant to dry completely, which typically takes about 24 hours, before applying paint. Make sure the surface is clean and dry before painting, and use a suitable paint that is compatible with the type of material you’ve applied CT1 to. How long does it take for CT1 to cure? Allow the sealant to dry and cure according to the manufacturer’s instructions. This process may take several hours or longer, depending on the sealant type and environmental conditions. Cheaper clear silicone and mastics can appear almost white instead of truly clear. In contrast, Adiseal Ultra Clear maintains a crystal-clear appearance both when applied and after drying. Silicone clear is cloudy compared to Adiseal Ultra Clear which is crystal clear.

Bodywork Repairs: CT1 is perfect for repairing bodywork, providing a strong and flexible bond even in high-stress areas. If you’re looking for a powerful sealant and adhesive that retains its colour without turning yellow in the future, you’ve come to the right place. CT1 Clear is one of our most popular colour variations because unlike other “clear” sealants, CT1 clear stays clear. Ideal for clear gutter sealing, it effectively seals gaps, joints, and connections while preserving your gutter system’s aesthetics. Adiseal Ultra Clear offers confidence in roofing and gutter projects with its flexibility, UV resistance, and exceptional waterproofing capabilities. Both products were applied to new clean plastics cups then filled with tap water half way. They were then both covered by plastic to make sure the cups were sealed. Both cups were kept next to each other in a dark location at room temperature (cool). This clear test in water was started on 13/07/23. The image was taken on 06/08/23 after the water was removed. The lot number of the CT1 sealant clear was 3843320 which we were told by C-Tec was manufactured in April 2023. The batch number of the Adiseal sealant ultra clear was 2253-0927.Application: M etals (including lead), Wood, Glass, Mirrors, MDF, Polystyrene, Fiberglass, Tiles, Concrete, Most stones, Most synthetic materials, Plastics (excluding PP, PE and PTFE) As can be seen in the image, Adiseal is better than CT1 in the clear sealant test in water. CT1 sealant clear has turned white above and below the water line whereas Adiseal ultra clear sealant has remained clear. CT1 sealant turned more white where it was exposed to the water below the water line. Both products were kept in the same water for 24 days. With TRIBRID® Technology, it is scientifically proven to have excellent colour retention – white stays white and clear stays clear. TRIBRID® Technology: A groundbreaking formulation that combines the best qualities of silicones, polyurethanes, and acrylics. UV resistant and Scientifically proven to have excellent colour retention – white stays white and clear stays clear

Adiseal Ultra Clear is a versatile waterproof sealant for both interior and outdoor use. Its flexibility and adaptability suit various sealing and bonding applications. With UV resistance, it maintains clarity and performance under sunlight, making it reliable for roof sealing and gutter repairs. It creates a transparent and seamless finish that effectively protects roofs from water damage. C-TEC has another CT1 grab adhesive with higher grab called CT1 Power Grab n Bond. Both CT1 Power Grab n Bond (PGNB) & Adiseal Hi-Grab are products with even higher instant grab adhesive.

Interestingly when we carried out this test with a number of different clear sealants on a previous occasion on 5th May 2020, the CT1 clear sealant old formula performed better than the CT1 clear sealant new formula.

Not all sealants or mastics are truly transparent when applied, often appearing cloudy instead. However, Adiseal Ultra Clear stands out as the top choice for a waterproof clear sealant. Unlike other products like clear silicone or mastic, Adiseal delivers exceptional clarity both during application and after drying, ensuring a crystal clear finish. Although CT1 adhesive was not tested by Ultimate Handyman in the above adhesive strength test, he did test the old formula of both CT1 adhesive and Adiseal adhesive in a previous adhesive strength. In that test, the old formula of Adiseal adhesive was shown to be stronger than the old formula of CT1 adhesive.

CT1 is the ultimate solution for sealing and bonding.

Some manufacturers often make exaggerated claims about their products, boasting about being “360% stronger”. However, it is important to question the validity of these bold assertions. Without supporting evidence, such claims can be dismissed as mere marketing hype. C-Tec also have another product called BT1 sealant but in a previous test in 2019, Adiseal was shown to have stronger mould resistance than BT1 sealant as well. Images of that test are available if required. Window Installation: It is widely used for installing windows, ensuring a weatherproof seal. Automotive CT1 was introduced in 1998 by C-TEC, a UK-based corporation. It was created as a one-of-a-kind hybrid polymer formulation to satisfy diverse bonding and sealing needs in construction and DIY projects.
