What materials are used for roofing brick joints

It is best to use soft materials such as plaster to caulk the roof square bricks, and the cement mortar will shrink due to its own reasons, and the ointment will avoid this problem, and the square bricks have a certain waterproof effect.

Exterior wall tile caulking can generally use pure cement slurry or caulk or caulking glue, but if the expansion joint depth is deep, the width is generally about 20mm, the innermost part is filled with polyethylene foam rods, and the surface is sealed.

During construction, there is a professional exterior wall tile grout machine, and the outer convex ribs of the portable trowel board move in the gap between the tiles or marble veneers of the exterior wall during the work, and the cement mortar in the cylinder is sent to the slurry outlet to flow out and fill the gaps, and form a concave cement joint by dragging.

There are also special (special for external wall insulation) ceramic tile grouting powder for exterior walls, (special for external wall leakage) ceramic tile grouting powder and other special grout materials, if there is no professional machine, you can use professional materials to hook the joint.

General exterior wall tile joints, are made of cement construction when there is a professional exterior wall tile jointing machine, when working, the outer convex ribs of the portable trowel board move in the gap of the tile or marble veneer of the exterior wall, and the cement mortar in the cylinder is sent to the slurry outlet to flow out and fill the gap, and form a concave cement joint by dragging.

There are also special (special for external wall insulation) ceramic tile grouting powder for exterior walls, (special for external wall leakage) ceramic tile grouting powder and other special grout materials, if there is no professional machine, you can use professional materials to hook the joint.

What to fill the gaps in the bathroom tiles can be waterproof, and the joint material must be selected to ensure that the bathroom does not leak.

Hello, the roof and floor tile grout method is 1Before caulking, clean up all loose animals and stagnant water in the gaps, and for porous tiles, the brick joints should be thoroughly moistened before caulking; 2.Add the caulk to a container with clean water in a mixing ratio:

Water can be added to each bag of caulk (2kg), stirred thoroughly until there is a uniform paste without cornstarch orange dough, let stand for 10 minutes, and then use after stirring; 3.Use a clean rubber ash knife or scraper to fill the gap with the stirred glue, taking care not to leave the bottom of the gap empty; 4.Clean the tile surface with a wrung out damp cloth or sponge in time.

It is best to choose a sewing agent of the same color, or similar color.

It is impossible to pave tiles seamlessly, so we need to deal with the gaps of the tiles when laying tiles, and there are many ways to deal with the gaps in the tiles. Among them, the commonly used materials are white cement, putty powder, grout, and beauty sewing agent, so which one is better? Let's take a look.

1. Grout.

The ingredients are white cement, trace polymers and pigments; The whiteness of white is about 86, and the surface strength is slightly higher than that of white cement; There are many colors of color caulk, but they are dull and dull, and the effect of antique brick hooking is generally slightly better; For ceramic tiles with bright colors and high gloss, especially for mosaic tiles and mosaics, the joints of these types are wide and many, and the use of colored caulk obviously affects the overall effect of the wall and ground from a distance, and the difference between the light and dark of the bricks and joints is too large and uncoordinated; The color caulk is easy to pollute the surface of the tile during construction, and it is more troublesome to clean, so most of them have to use white caulk to hook the joint; After the use of colored caulk, the brick joints are very easy to get dirty like white cement, which is why people often choose black caulk when they hook the floor tiles, because the use of other colors will quickly bloom and be difficult to scrub clean. Second, the beauty sewing agent.

After curing, it is composed of polymers and high-grade pigments and trace additives, with rich colors and bright colors, and has gold, silver, pearlescent and stainless steel colors, which are suitable for matching with various color tiles; White white or the degree of reading is about 95, the surface strength is high and the toughness is good, its surface is smooth, easy to scrub, easy to clean, waterproof and moisture-proof, avoid sanitary dead ends, can often maintain the original color, and will not pollute the tile during construction; It is the most cost-effective to use a sewing agent.

3. White cement.

The color is single, divided into ordinary white cement and decorative white cement, the former has a slightly higher intensity, whiteness is about 80, and the latter has a lower intensity, whiteness is about 84; In short, the whiteness of white cement is low, the paste strength is low, the chalking phenomenon is serious, the brick joints are easy to yellow and dirty, and it is a mold breeding ground in a humid environment.

Fourth, putty powder.

Also known as binder, it is the most critical component of putty, mainly playing various roles such as bonding. The most commonly used binders for putty are cement and organic polymers, which are divided into emulsions and latex powders. Cement is a binder with good cohesiveness, resistance to base sensitivity and reasonable cost performance, but it has poor tensile strength and crack resistance.

Organic polymers can be modified and toughened to improve putty performance.

It can be seen from the above introduction of what is good for tile joints, the four materials have their own characteristics, and we can choose the right tile caulking products according to their own needs when paving tiles.
