Pool Shell Densifier – SD400

A non-hazardous, user friendly, permanent densifing/hardening sealer that waterproofs and prevents efflorescence on new and existing concrete pool shells and raised walls.

SD400 is a multi-phase penetrating lithium-colloidal based proprietary silicate treatment that reacts with concrete to produce insoluble calcium silicate hydrate that locks aggregate together and fills vacant concrete pores while building a water-resistant matrix. SD400 is an effective solution for preventing water seepage and efflorescence in concrete.

SD400 is faster and easier to apply than other pool shell protection products – it can be applied with a pump-up sprayer and in addition, SD400 eliminates the need for the pool owner to water the shell surface (hydrating) during its initial curing stage.
