That’s *Dr. Fixit Pidiproof LW+ 101* — same product as the yellow bucket you sent earlier, just a different size/container.
*What it’s used for:*
It’s an *integral waterproofing admixture + “tonic for cement”*. You mix it directly into concrete or mortar while batching.
*Key benefits from the label:*
1. *Provides integral waterproofing* - Makes concrete/mortar itself water-resistant, so structures like water tanks, basements, bathrooms, parapets, and terraces don’t leak.
2. *Increases concrete strength* - Gives higher compressive strength to the mix.
3. *Delays corrosion* - Reduces water/chemical ingress, so the steel reinforcement inside concrete rusts slower. Very important in Nigeria’s humid/rainy climate.
