Does the filter sand need to be changed every spring when starting the pool?

Changing the filter sandshould be done to get your pool ready for the season latest after 2 to 3 years.
Sand-grains lose their cleaning power over time and cause insufficient cleaning power of the filter.

Old filter sand can lead to problems to get and keep the pool water into the clear and clean state you like to have for your family.

What is the difference between underwater adhesives?

pool repair underwater

Let us explain some wording…..

1. suitable for underwater use
Means that a product can be used underwater.

2. fresh-, and saltwater resistant
Means a product is suitable for rain- and pure seawater

3. made for fresh-, salt- and swimming pool water
This is what you are looking for as a pool owner, since it is the only
solution for swimming pools since all swimming pool sanitizing systems
use chemicals for a good pool water quality.

Swimming pool chemicals destroy products of 1. and 2. in a matter of days or a few weeks and leaks will come back, tiles will fall of again, patches peel off or pool lights will fall off again…

Underwater Magic is made for swimming pools and works perfect for pool-, sea- and fresh water applications of all kinds like horizontal-, vertical applications, for heavy items like large format tiles or special tasks like expansion joint’s, grouting and leak sealing with out any mechanical support during curing……..

Does your Pool need a repair in the middle of the summer

The worst case scenario for all pool owners in the summer:

The pool needs an urgent repair!

Leaking skimmers are often the reason for a water loos in a pool and  is big problem for any pool, since this can lead to a structural damage.
Lowering the water level to do a repair in dry conditions cost a lot of water and chemicals.

Loose or broken tiles are the main reason for cut feet in swimming pools,  but emptying the whole pool in the middle of the summer is not an option but needs to be done, in conventional repairs, to prevent swimmers injuries.

Screws of drain covers, lights or ladders are getting lose and it is impossible to get them tightened.

Pool vinyl of above ground pools got damaged from pet’s ,lawn mowers etc. or the bottom seal got loose over time.

There are many reasons for pool repairs when the summer is in full swing and the pool can’t be emptied for commercial reasons,  family peace and / or it is simply too expensive.

There are even countries where you have to apply for a permission to empty and fill a pool from the government and that takes time or get denied for reasons like drought, disposal of the water issues etc.

A repair underwater is the only solution to save the summer, but is there a way that underwater repairs in swimming pools last?
Due to the pool chemicals attacking the repair all the time even in a saltwater pools or with one of the new sanitising systems where it seems no one has experience if a repair would last.

The answer is yes!

Scientists and pool pros have developed a magical product  which is made for underwater swimming pool repair and sealant work.

Lasting results was what they had in mind when they started the project and in 2010 Underwater Magic adhesive and sealant has been launched on the market.
