Contract a pool contractor to refab your pool. Will cost you extra for removal, but leave it to the professionals. Get multi bids from big and small companies. Never give a huge deposit up front.
sand it or grind it out depends on what finish you want
Be more specific please- what about removing it? cost? difficulty? What type of pool is it? fiberglass? vinyl liner? concrete?
here is no way to actually remove it other than light sanding then finish off with a clear coat hard paint. Krylon spray is best.
I don't know about fiberglass but I got wood stain on my nearly-white carpet and it came right up using hydrogen peroxide. It didn't bleach out the carpet either! Hope that helps.
You can remove dried barnacles from a fiberglass boat using a stainless steel scrubber or a pressure washer for large barnacles.
by using "BANG"
You have to NAME the glue before we can answer that.
no it does not
Baking soda is the best way to remove acid stains from concrete. Dawn may remove grease stains from concrete. Vinegar is another great solvent for grease stains.
No. An older (possibly better) type of Fiberglass pool was constructed in this manner, with a concrete/Gunnite/Marcite trowled bottom and Fiberglass panels at the side of the pool. Panels are caulked together along vertical joints. Actually not a bad deal, but caulked joints must be maintained. Once the concrete starts showing through at the bottom of the pool, its time to drain and resurface. Bottom of pool should be acid washed every 3-5 years to keep it sparkling and remove mold, mildew, stains. If bottom surface is chipping off, its getting close to time to resurface bottom of pool. Bottom is treated just like any concrete/gunite/Marcite pool surface. Sides are simply brushed, caulked in timely manner.
scrap it off with a knife or sharp object
Many stains can be removed with alcohol.
