⚠️ CRUCIAL APPLICATION RULES (HOW TO US THE SEALANT)
Read Before Applying

Because this is an advanced engineering weather-resistant adhesive, it binds extremely hard. Please follow these exact steps for maximum results:

  • 1. The Surface Must Be 100% dry: Wipe away all grease, water, or oil from the surface before applying the glue. If the surface is wet while applying the sealant, it will not seal properly. To seal watertanks, storex or buckets, apply the sealant IN & OUT.
  • 2. Wear Protection / Nylon: Always protect your bare hands by wearing nylon bags or hand gloves. This product is incredibly tough and very hard to wash off your fingers once dry—except by scrubbing hard with raw sand and soap.
  • 3. Leave to Dry for 3+ Hours: Do not rush it or pour water on it immediately. After application, leave it completely untouched for at least 3 hours. Remember: Just like cement. The longer it dries, the stronger the bond becomes!

Here’re few questions you might probably have in your mind right now and their answers.

Will this sealant damage my car paint, tiles, or water tank surfaces?

Absolutely NO.

This 9900 engineering adhesive is strong on cracks but safe on structural surfaces. It is designed to tightly seal leaks without corroding or scratching plastics, glass, metals, granite, quartz, ceramic, or wood.

So you can fix your home and car assets confidently without fear of damaging anything in your property.

Why does the surface need to be perfectly clean before application?

For the industrial chemical compounds to create a 100% airtight seal, they must directly bond with the target material. Dust, grease, water droplets, or old dirt particles form a barrier that will weaken the grip over time. Always clear and dry the area completely first!

What happens if the adhesive touches my bare fingers?

Because it is optimized for heavy-duty weather resilience, it dries into a highly stubborn skin. If it touches your skin, it will not cause burns, but it is extremely difficult to wash off with standard soap alone—you will need to firmly scrub your skin with fine sand and soap to clear the residue. Always wear nylon protection while using it!

How long must I leave it to dry before using the item?

The initial chemical set requires a minimum of 3 hours completely untouched. However, the compound continues to crystallize and strengthen over a full day cycle. Always remember the professional rule: The longer you leave it to dry, the stronger it becomes.
