# Bostik Freeflow

Bostik Freeflo 5L Waterproofer & Retarder waterproofs is a liquid admixture which waterproofs, retards, and plasticises cement-based mixes.  
  
It provides protection against driving rain and damp conditions and extends the mix setting time to allow larger areas to be worked in a single application. It also improves the workability of the mortar. It has been specifically designed for use in pebble dashing & rendering and general above-ground waterproofing work.  
  
**Benefits**  

-   Slow setting time makes it ideal for covering large areas in one application
-   Reduces water penetration without acting as a vapour barrier
-   Creates smooth, easy-to-work-with mortar
-   Can be used for rendering, roughcast, pebble dashing, harling and above-ground waterproofing
-   Aid workability by entertaining air
