Bead blasting paint from a concrete curb by a worker wearing hearing protection. Mixing particles with water substantially reduces dust. Bead blasting is the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface.
Soda blasting can be used for cleaning timber, wood, oak beams, oak floors, doors, stairs & banisters, cars, boat hulls, masonry, and food processing equipment. Soda blasting can also be used to remove graffiti [2] and to clean structural steel. Soda blasting is very effective for mold and fire/smoke damage cleanup as it cleans and deodorizes.
Whitewash can be tinted for decorative use and is sometimes painted inside structures such as the hallways of apartment buildings. A small amount can rub off onto clothing. In Britain and Ireland, whitewash was used historically in interiors and exteriors of workers' cottages and still retains something of this association with rural poverty ...
The effect copper slag has on concrete compressive strength was found by performing compressive strength test on various 7- and 28-day concrete mixes. The ratio of copper slag to sand in each mix varied by 20% increments from 0% to 100%. With each mix having a unique amount of copper in it the effects of cooper slag on concrete are observable.
Concrete floor polishing works by smoothing out peaks and valleys in the surface; if the concrete is not strong enough, this abrasion will remove micro-chunks that decrease the surface uniformity and quality of shine. Concrete surfaces face two major obstacles to polishing: bleed water and pores.

Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
The lime makes the render more workable and reduces cracking when the render dries. Any general purpose cement can be used. Various additives can be added to the mix to increase adhesion. Coarser sand is used in the base layer and slightly finer sand in the top layer. The application process resembles the process of applying paint.
