When the grout is poured directly on the pavers, the wood float or a steel trowel is used to force the grout into the joints, using semi-circular motions. Generally, a steel trowel is used on larger areas. Once the joints have been completely filled, the float or trowel is held on edge and moved over the surface in directions that are diagonal to the joints to remove as much excess grout as possible from the surface.
If the joints are too pliable to finish properly, a small amount of the dry mix used to make the grout can be sprinkled over the area so a proper finish can more readily be obtained. Spread the dry-mix into the surface evenly, then scrape off the excess. After the joints have dried to thumb-print hardness, wipe off the grout left on the paver surface with a piece of dry burlap material.
If the area paved is a large open area, the "ragging-off" method of cleaning and dressing the joint is generally suitable. This is done with a wet blanket or a piece of burlap about six feet long which has been doubled over. This section now is "ragged-off" with a wet blanket or a piece of burlap about 6 ft. long which has been doubled over. This ragging-off method is generally suitable to large, open areas. The mason pulls the burlap or blanket toward himself, and diagonally across the joints, as he walks backward.
It is important that the rag be wet enough to make its weight equal at all points to provide a smooth, even joint finish. It should be soaked in water long enough to make it soft and pliable. It will generally be necessary to repeat the "ragging-off" operation several times in the same area, thoroughly rinsing the blanket or burlap regularly. Each time the "ragging-off" operation is repeated on the same section, the blanket or burlap should be wrung out slightly drier.

SAFWAY has designed a new guard rail retention system for use on standard SAFWAY manufactured scaffolding. The new system, called a "G-Lock"" (patent pending), is not interchangeable with existing guard rail posts. The purpose of this announcement is to urge all users of SAFWAY products to convert their existing guard rail retention systems to the G-Lock system.
The existing guard rail system, which utilizes a threaded stud and wing nut to hold the guard rail in place, is safe when the scaffolding is properly constructed and used. However, it has come to our attention that improper construction and misuse of the existing guard rail system has resulted in a number of accidents, some of which have caused severe injuries. The G-Lock system is designed to minimize such improper construction and misuse.
For this reason the new G-Lock has been incorporated into all SAFWAY inventory and newly manufactured SAFWAY equipment. In addition, we are offering to convert all other existing SAFWAY manufactured equipment to the G-Lock system at our expense.
We urge you to replace your existing SAFWAY guard rail system with the G-Lock system. You simply need to bring your SAFWAY guard rail posts to your SAFWAY dealer for a no cost modification or exchange for modified SAFWAY guard rail posts.
If you have any questions regarding this announcement, contact your SAFWAY dealer or Robert Freuden, Manager, Customer Service, Safway Steel Products, P.O. Box 1991, Milwaukee, WI 53201 (414) 258-2700.
