Light sanding

Several coats of resin are applied to the prepared substrate at approximately 4- to 6-hour intervals, with one or more coats being dressed with colored paint flakes which are sealed in by the next coat and then lightly sanded. This type of flooring was widely marketed about ten years ago but, in the main, they were considered unsatisfactory due to rapid discoloration of the floor because of the lack of ultraviolet stability of the urethane resins used, which rapidly turned yellow-brown and looked dirty. However, ultraviolet-stable urethane resins that do not suffer this discoloration are now available, and this type of durable decorative flooring is gaining re-acceptance (for example, for kitchens, toilets and reception areas). 

After the bare metal is primed, the whole area is built up with primer-surfacer. After light sanding where necessary, the repair is completed with topcoat. The materials used in the primer-surfacer are matched to the selection of topcoat. Topcoat is chosen from four main types. 

When a deposit is tested with concentrated HC1, then made alkaline to precipitate iron, and finally the solution is filtered, the presence of copper is indicated by a clear blue color in the filtrate. Also, if a lightly sanded nail is inserted into the acid test solution, any copper present will plate out on the nail. 

In the mineral kingdom there is nothing but water, common salt, pure vitriolic salts, and light sand and stones in which the substance is little or not at all found. On the other hand, coal and bitumen are full of... 

In many cases a light sanding of the substrates in advance of application was found to improve the strength of the bonds. 

Substrate cleaning usually involves the light sanding of a clean, dry bonding surface. A primer (urethane or silane) is sometimes used to improve adhesion. Urethanes are generally bonded with a flexible epoxy or a urethane adhesive system. 

Lightly sand one surface of each silicone strip. This will aid in adhesion. Make sure to clean the surface of the rubber strips after abrasion. 

Lightly sand the areas where the PVC pipe coupler will be in contact with the surface of the inside of the top flange. Sand the contact surfaces on both the flange and the coupler. 

The test specimens were right circular cylinders of 1.27-cm diameter and 3.81-cm length, conforming to ASTM D695 standards [% To make these specimens, the commercial rods, as-received from the manufacturers, were cut to length, their faces machined parallel, then lightly sanded until smooth. All tests were made with compressive loads applied parallel to the longitudinal rod axis and hence parallel to the unidirectional fiber or cloth direction. The rods were tested in the as-received condition. 

The soil s character and the underground water level are important factors. High water levels and heavy soils could increa plant construction costs by 7%-12% in comparison with light sands with low w ater levels. 

If weathering causes color change or differential fading, the PVC member can be painted after proper preparation of the snrface by washing and light sanding.

Peas suit deep, free-working loams. Pea roots are very sensitive to the physical condition of the soil and compaction and waterlogging are very damaging so light sands and heavy clays are not suitable. Peas do not grow at temperatures below 4.4 °C so overwintered fresh peas are only suited to frost-free coastal areas in the south of England.

During the generative production, the component is supported from the surrounding powder must be removed by light sanding (post-processing). Thereafter it can be used. 

Other methods include vapor degreasing in methanol, sanding or vapor blasting, and alcohol-wipe and/or light sanding, plus vinyl, urethane, or silicone primer. 

Siliea Sand BX40 is an efficient and cost-effective abrasive medium except for the potential health problems. A vacuum-abrasive cleaned area on steel yielded results similar to those obtained with Starblast and Black Diamond. The surface profiles of metal and wood substrates after cleaning ranged from 0.5-1 mil, which requires light sanding before painting.
