How Masons Actually Use BS Drycrete at Site
BS Drycrete is very simple to use. It is mixed in the water used for mortar or concrete.
Follow this method for best waterproofing performance.
For External Wall Plaster (Most Common Use)
For 1 bag cement plaster mortar
Typical plaster mix:
1 Bag Cement + Sand as per site mix
Add:
200–250 grams BS Drycrete per cement bag
Mixing Method
-
Take the required mixing water in a bucket.
-
Add 150–200 grams BS Drycrete into the water.
-
Mix the liquid properly in water.
-
Use this water for making plaster mortar.
Important
Reduce total water by 10–15% compared to normal plaster.
This produces dense plaster that resists rainwater seepage.
For Concrete Works (Terrace / Water Tanks)
For 1 bag cement in concrete mix
Add:
300–350 grams BS Drycrete per cement bag
Mixing Method
-
Add BS Drycrete to the mixing water of concrete.
-
Mix properly before adding to concrete mixer.
-
Reduce water by 10–15%.
This helps produce dense waterproof concrete.
Site Tips for Better Waterproofing
-
Do not add BS Drycrete directly into dry cement.
Always mix it in water first. -
Do not increase water to make mortar loose.
More water reduces waterproofing performance. -
Proper curing is essential.
Keep plaster or concrete wet for at least 7 days. -
Use good sand and proper mix ratio for best results.
Example from Site
Without BS Drycrete
Normal plaster absorbs rainwater through micro pores, causing:
• damp patches
• paint peeling
• internal seepage
With BS Drycrete
Capillary pores become smaller and denser, resulting in:
• lower water absorption
• stronger plaster
• improved waterproofing
