Q1: Can I get samples prior to placing large project orders?
Absolutely. We offer test samples so you can verify adhesion, material compatibility and waterproof performance at your jobsite. If you want to compare multiple sealant formulas, mixed sample packs are available.
Q2: How much time is needed for sample preparation and mass‑order production?
Samples get ready in 2‑3 working days once confirmed. After your deposit arrives, mass production will be completed within 5‑7 working days.
Q3: How many cartridges do I need as minimum sample for testing?
Just 1 cartridge meets your testing needs. It is sufficient for laboratory compatibility tests and basic waterproof inspections on construction sites.
Q4: What shipping methods do you use for samples and bulk orders?
We ship full‑container bulk orders by sea to keep your total cost competitive. Small test samples are sent out by DHL or FedEx for fast international delivery.
Q5: What does your typical ordering process look like?
Send over your project parameters, application scenarios and technical requirements. We prepare a custom quotation for you. After sample approval, submit deposit payment, we start mass production and arrange shipment for you.
Q6: Do you support OEM private label with my brand logo on tubes and outer boxes?
Yes, OEM branding service is available. You need to provide high‑resolution logo files plus written confirmation before we start production.
Q7: Does this mid‑grade sealant carry long‑term warranty for building projects?
It comes with standard product quality warranty for general construction sealing applications. Long‑term engineering warranty for building facade projects is not applicable for this product.
Q8: May I use this sealant on swimming pools, fish tanks and glass water tanks?
It is suitable for non‑pressure decorative aquariums and landscape glass features. Avoid using it on swimming pools, pressure‑bearing water tanks and areas permanently under water.
Q9: Can you make special colours for my decoration projects?
Standard colours include transparent, white and black. We can perform custom colour matching according to your construction drawing references.
Q10: What is the shelf‑life for unopened sealant cartridges?
Unopened cartridges can be stored for maximum 18 months when kept dry at 5℃‑27℃.
