P3 Water Stop:

Our most frequently asked question is: ‘What would YOU recommend’

Here at East Riding Koi we work on the theory of trying out as many of the products we sell as possible, and the ‘P’ range of products are all by far our number one favourites!

This P3 Water stop is a blend of Cement, Polymers and Graded aggregates....You may ask what is the difference between P3 and other cements - P3 will set in 60 seconds at 20 degrees C

Another product that we are confident in recommending, with excellent reports since this product became available we are sure it will continue to succeed...

Please note that P3 is a registered brand trade mark and it is only sold under the brand name of P1 and it has no connection with any similar, and inferior products that are being advertised using a similar product .......






Key Factors:

  • Fast Setting Speed makes P3 ideal for stopping leaks in waterfalls.

  • P3 can be used on any Concrete base.

  • P3 allows an over coat of P6 Pondalite and P1 Pond coating.

  • P3 can be used on render - Good for hair line cracks.

  • P3 can be mixed with a small amount of water to create a paste before applying - Remember P3 sets fast!
