Hi good day. I would like to place a plastic pool on a material platform (attached photos) but first I want to provisionally fix a crack that exists next to it. Would you tell me how to do it? In the center there is also one from the wall forward but it is very finite; I would rather not touch it (if I would not have to do the new platform and it is not what I am looking for and I can at this moment). plataforma.docx [3.11MB]

If you are going to place a plastic pool, what is the point of worrying about a crack? I do not know how thick it is because in the photo it is not seen in detail but if it is 5 cm thick it will hold the weight well.

you would first clean the surface after filling with this product http://www.beissier.es/es/productos/producto_2438.html which is a joint sealant for tiles and then apply concrete barnis or concrete floors and ready salu2
