Which of the following is the recommended seam groomer after hot-melt seaming?

The recommended seam groomer after hot-melt seaming is the smooth or paddle roller. This tool is crucial in ensuring a proper bond between the seams by evenly spreading adhesive and providing adequate pressure. The smooth roller is typically used for its ability to create a flat finish that aligns the edges of the seams perfectly, ensuring there are no gaps where moisture can penetrate.

Utilizing a paddle roller, on the other hand, contributes to the same objectives but is less common specifically for this purpose compared to a smooth roller. The paddle roller often assists in other flooring applications, primarily focusing on different materials or textures.

Having a seamless appearance and adequate pressure on the seams after the hot-melt process is essential for durability and the overall aesthetic of the flooring installation. The combination of both smooth surfaces and the right amount of pressure helps secure the seam, thus preventing any potential lifting or issues in the future.
