No, salt water in a properly water-balanced pool will not damage grout, tile or concrete around the pool. Damage to such surfaces will come from improperly balanced water that will either scale (deposit onto) or will corrode (pit and dissolve) the calcium carbonate in grout and concrete. Water balance is determined by pH, Total Alkalinity (adjusted for Cyanuric Acid), Calcium Hardness, Temperature, and Total Dissolved Solids (TDS). For more technical info, go to http://www.corrosion-doctors.org/NaturalWaters/Langelier.htm I have a spreadsheet that calculates this and couldn't find a website that did it all right including TDS which for salt pools would make the index about 0.1 higher than reported by a website such as the following: http://www.aquachek.com/calculators.asp?action=lcalculator&CID=4

Grout is used to fill spaces concrete will not flow into. Grout is more watery than concrete and the expectation is that the water will be absorbed into the surrounding materials and the remaining grout will reach design hardness. Concrete, to the contrary, is expected to retain its water and the amount is carefully calculated.

if the salt water pool has a extreme high mineral content it ,could make the grout white, if the grout is new.

Grout is a material used to fill voids in concrete or tile structure. Grouting or Injection Grouting or Pressure Grouting invariably means the process of injecting grout into isolated pores or voids in a concrete or tile structure.Eg:- Injection grouting in a concrete water storage tank.

Concrete can be damaged by fire, orgonite, aggregate expansion, sea water effects, bacterial corrosion, leaching, physical damage and chemical damage (from carbonation, chlorides, sulfates and distillate water).

If you are using a concrete substrate as the base, the concrete should be free of any construction debris and any barrier [like paint or drywall texture] that may be on a surface. You should waterproof the host concrete material 1st before setting the bed. I recommend using a product called StableCrete to waterproof the concrete. This will give your mud superior adhesion to the concrete and will also prevent moisture from coming Up through a slab to cause bond problems at a later date. Cement based grouts are very porous and will absorb water and stains dropped on a floor surface. If you waterproof the grout joints you will see years of an original color joint not subject to absorbing contaminates. This also prevents moisture from migrating down into a grout and penetrating to the bottom if a tile where that moisture can compromise the tile to mud joint bond. If you have ever had to remove grout, pull up tiles, re-mud with thin set, reinstall your tile and then re-grout, you will appreciate your waterproofed bonding! [Not for use on Polymer based grout]. Essential for longevity and maintenance of any concrete or cement grout to waterproof it!

If grout is damaged by cleaning, it was a poor job to begin with. Usually the problem was too much water used when the grout was mixed. Ordinary grout can be cleaned with a mild solution of bleach and water and a medium stiff bristle brush-a floor scrubbing brush.

User Avatar

You should only use a mild soap and water solution for cleaning grout on floor tile. If it was properly sealed this should work fine. If it was not sealed and the dirt has worked its way down into the grout, you can either use a grout renew which is sort of like a paint for grout, or you will have to have the grout replaced.

One way to clean grout is to make a mixture of baking soda and water and applying with a scrub brush or toothbrush. One can also make a mixture of bleach and water, apply to the grout, and let it soak for 15 minutes before scrubbing. There are also commercial products meant to clean grout, including MK Tile and Grout Clean.

The best acid mixture for cleaning grout off of tiles is muriactic acid and water. Great care must be applied when using this acid as it is extremely dangerous. The acid must be added to the water and not the other way around.

Break away the concrete until you find the leaking area then repair. Re fill with new concrete.

User Avatar

Water damage repair costs depend on the type of water that was leaked. The more polluted the water is such as grey or black water, the higher the damage cost because this water contains toxins. But the typical cost for water damage repair is around $5000.

Water can damage the foundations of a house and they can suffer badly from the effects if they are made of concrete. While water damage to carpets and furniture is a pain, foundations that has been damaged by standing water can be a big problem as it can affect the structure of the building. This damage caused by flooding can not only weaken the foundations but in the worst cases, potentially cause the house to become unstable.

Not generally. If the concrete has a sealent on it no, but if you have a massive amount of water on unsealed concrete, the concrete will absorb the water and can make it swell and possibly crack. Answer The answer given above is totally incorrect. As far as only concrete is concerned i.e. plain concrete, the effect of water seepage is very little (depending upon the grade of concrete) whereas for RCC (reinforced cement concrete) water that seeps in corrodes the reinforcement and thus reduces the life of the structure. The defects that water seepage induces in concrete are as follows: 1) induces capillary formation (due tothe detiorating characteristics of water) 2) With this capillaries the concrete starts spalling out i.e the places where capillaries are formed, with even slight amount of stress that portion comes out and exposes the steel to the atmosphere 3) Concrete has a pH of about 12 -13. Thus it also reduces the pH of the concrete when salty water or when the concrete is exposed to marshy areas. 4) Reduces the overall strength of concrete 5) Reduces durability 6) Reduces permeabitlity to further water seepage 7) Results in ageing of structures

Grout was not properly mixed. It most likely mixed with to much water. Your water could be aggressive with a low pH attacking the grout and plaster. Test and adjust. If your pH is below 6.8 and has stabilized there your pool plaster should start to look copper color, aqua color, have black stains which look like graying spots. But once the damage is done you can't undo it.

rock salt is an old standby but has been known to damage the concrete over time. I've been told that the salt used in water softeners does a good job and doesnt harm the concrete.

User Avatar

Yes you can. Substitute 20% of the water for the cement mix with latex paint (Water based paint) and mix slow and thorough. Don't over used too much paint it will damage the integrity of the concrete.

The best flooring by far for a kitchen is ceramic tiles with an epoxy grout. They will last a long time won't take any water damage and increase your home value.

The material that is used before tiling a tub surround and ensure no water damage is known as concrete backer board, sometimes referred to as green board.

If you have never installed tile and grout before, it is pretty easy to learn how to do grout. The first thing you need to do is to look at the width of your grout lines. If it is going to be less than 1/8 of an inch, you want to use non-sanded grout. If the width is more than 1/8 of an inch then you want to use sanded grout. Make sure that you put all of your grout tiles in place first. Use spacers to make sure that there's an equal distance between all of the tiles. Then, you want to mix your grout paste and use a float to make sure you fill in all of the grout lines. the grout mixture should look like wet sand if you're using sanded grout, or it should look like thick cake batter if you are using non-sanded grout. Grout tends to hold better if it has just the right amount of water. It has too much water or too little it doesn't bond properly. After you are done filling in the grout lines, take a large damp sponge and wiped the tiles clean. That is it, you are done!

Not really a good idea. The water over time from the concrete will cause the board damage. If you use a good pad there is no reason you cannot lay the carpet over concrete.

The pH of water for making concrete is 6 to 8.The water should be free from organic matters.Sea water should not be used for making concrete.Potable water is used for making concrete.

Grout is porus and degrades after time, the proper item to use would be caulking ( non porus and waterproof) also degrades, but can be replaced easily. Grout is preferred because it lasts longer, is pourous to a degree and will let water evaporate so that mold will not grow. Caulk is used for more temporary bonds such as between the sink and a painted wall. Grout, if installed properly can last you a lifetime.

Concrete is corroded by salted water.

User Avatar

== == Water can very well find it's way through the floor. It is usually at areas where the tile meets a vertical area at a shower or tub. Movement can occur in these areas. It is best to caulk joints such as these, instead of grout. The caulking will flex, but the grout will crack and allow water to penetrate.

Grout is a construction material used to embed rebars in masonry walls, connect sections of pre-cast concrete, fill voids, and seal joints (like those between tiles). Grout is generally composed of a mixture of water, cement, sand and sometimes fine gravel (if it is being used to fill the cores of cement blocks). Sometimes color tint is applied as a thick liquid and hardens over time, much like mortar.
