Polished concrete is strong, durable and low maintenance, while the earthy texture of stone with a glaze like granite. Here's how.
It 'is comparable with traditional polished terrazzo, which is very flat and launched as a special mix to achieve the goal even more successful. Concrete floors can also see almost rough and little or no representation of aggregate. Flatness and polishing are not necessarily the same thing to clear up a good point, before it isYour project.
Angle Grinder
It costs more time and wear diamonds cut with a concrete floor grinder until the batteries are low. You can completely polished flat to expose the unit as a terrace, or the drive may be partially exposed, or the rings of concrete can not reveal more than the fine sand on the surface. Often it takes skill and experience to the process of concrete floors polished and the quality of the original concrete work is also a controlling factorin the quality of the surface. If the total amount a feature special materials on the wet concrete mix, such as colored stones, metals and glass to improve the final appearance will be added.
Most people are not aware of the fact that it takes 10-15 points for polished concrete floors for a long time to complete and can be very expensive.
Usually it takes a lot of grinding going on a gloss piano, although there are other ways, as will be explained later. The general ruleAnd 'the size of diamond grains in the concrete grinder double for each step at a party with very coarse grain may start 16 or 32 diamonds, then use the diamond grit 60 120, then again with a resin 50 grit diamond pad instead of a Metal segment. With resin pads, just steps 100, 200, 400, 800, 1500 and finally 3000 grit. That would be ten distinct steps of grinding, not to mention the other two major phases.
Two other important Steps:
Hardening the surface 1
Concrete floors usually have treated the surface with a first chemical step of the second, third or fourth amendment. The chemical penetrates into the ground from a few millimeters (up to an inch) and causes a chemical reaction that polish the floor harder and easier to take part in a high luster. These floors are very strong and durable, with no solid surface.
Holes 2 Fill
After the first results> Grinders pass the top layer of concrete to add the millions of tiny air holes is set. If these are not filled prior to hardening, the final polished concrete floors, these unsightly defects. The holes are usually with an acrylic adhesive tiles type of product, both the abrasive dust and cement powder to deliver the floor is scraped with a spatula, filled mixed. The best way is to fill the holes, the acrylic adhesive splashSchleifer, so that the mixture into the holes with the diamond powder polishing step on the third or fourth to about 120 grit. This method is faster, and the dust is the color of the soil around the holes better than to hide the use of cement dust.
Very polished flat or slightly irregular?
Some floor sanding machines are designed to be a very shallow soil are developed by the truncation of the highlights, while others, the contours of the land to produce more children. If 'Surface, without necessarily exposing the aggregate then, only the finest resin pads is located on a concrete grinder that allows the movement of the pad, so that they can follow the contours of the surface are used for polishing. This is a polished floor, without the model and the structure of exposed aggregate in concrete, which is faster and cheaper results. Hardening can still be beneficial for the durability of the surface and produce a finalGloss.
Problems with concrete aggregate
Sometimes the surface of exposed concrete aggregate can be irregular if the concrete mix was poured unevenly or poorly finished. Marks the start or marker board in the knee can occur suddenly pressed it to further reduce the unit, which may require sanding or two or three millimeters (one centimeter), which will cost more than was quoted. Loop can not be, as far as what the customer wanted and then it could be aRisk.
Single head or multiple head machines
The original terrazzo floor grinding wheel to make a single head of global production in three cars headed. Planetary means that every head turns in one direction, while the turntable, which is independent of both the heads of the houses in the same direction or opposite direction. Some mills may change the direction of the plate and the heads and some can vary the speed of each. There are alsomulti-head machine with four heads or more planets.
The planet-heads can better follow the contours of a single or dual-head-grinding machines are faster and with less effort, eliminating the need to physically move the mill from page to page, or use it in a circular motion. Single terrazzo grinder head must be avoided in a circular motion, grinding shoulders or lips move.
Border
As should be completed at the edges of wood flooringseparately on the main floor space, because the big machines can hurt and damage the walls, if used too close. For the grinding passes first nine inch angle grinder is used, equipped with a diamond disk of dust collection shroud, fixed to remove the dust. The sit-down-to-use on-board mills are more controllable and knees to get up-to-use grinder mills have good control, but tiring.
Cut after the first two or threedifferent dust collection shroud with a characteristic angle is polished with a polishing or seven inches in a five-inch multi-speed grinder with resin pads and used in confined areas.
Simple concrete floors polished "look"
The number of processes for polishing concrete is up to 60%, but a similar appearance by sanding and painting with a clear sealant. The first step is to work with 30/40 grit diamond grinding to expose the aggregate, thenfill all the air vents just as described previously (10 to 15 steps before a second ....) grind with gravel or sand 60/80 80/100 diamonds.
The smooth surface is sufficient to coat it with a sealant. Polyurethanes are kept very hard with high gloss and can be used as UV-stop yellowing be purchased (usually twice the price of non-UV stable urethanes) are not as clear epoxy sealant and smooth plaster and worse when the light the sun and acrylic sealants are exposed to a much shorterTheir lives because of their poor wear resistance. Two coats are necessary to give a high gloss.
Various types of "polished concrete" to get
The first is to cut the floor with diamonds, all the high points have been removed to produce a flat bottom and then every 12 to 15 steps at last polished or as it is sometimes called, will improve. This is the real polishing system.
A variant of the above, perhaps half the height of cutPeaks of growth with a medium grit diamond in the rough and guide to polishing with a car that can drive and smaller.
A third alternative to a piece of ground is covered with fine diamonds and relatively easy to polish the surface after curing without beginning from the very top of the concrete. It 's easier to do if the floor is laid flat and smooth.
Finally, a look "polished" by sanding with coarse receiveDiamonds and diamond well then, prior to coating with a clear sealant.
Only very polished floors will maintain their shine with little maintenance, since all levels with scratches and wear lose their luster. Special polishing pad polisher to a standard that may contain very fine diamonds are used to maintain the cleanliness and the high gloss polished concrete truth. Carers can be made available with this and keep the soil in good condition, with no specialTreatment.
Some car rental companies offer the grinding equipment for the do-it-yourself concrete polishing and have all the pads for the purpose. This is perhaps not the most efficient, but because the pads can not be half worn when you're done, depending on the affected area.
