Q1: Are free test samples available prior to placing large project orders?
Yes, we provide test samples for customers to verify adhesion strength, material compatibility and waterproof performance. Mixed sample packs are also offered, allowing buyers to compare the performance of different sealant formulas before bulk purchase.
Q2: How fast can you prepare samples and complete bulk production orders?
Our team can finish sample preparation within 2 to 3 working days. Once we receive your deposit payment, mass production will be completed within 5 to 7 working days.
Q3: How many samples do I need for testing?
A single cartridge is sufficient for both laboratory performance tests and on-site construction evaluation, which helps you save testing cost.
Q4: How do you ship samples and bulk goods?
For large bulk container orders, sea transportation will be adopted to minimize your shipping cost. Small sample parcels are delivered by DHL or FedEx to achieve fast worldwide delivery.
Q5: What is the complete ordering process?
First, send us your project details and technical requirements. We will prepare a customized quotation for you. After samples are tested and approved, you arrange deposit payment, then we start production and arrange shipment.
Q6: Can you print my logo on tubes and boxes?
Yes, OEM private label service is fully supported. You only need to provide high-definition logo files and confirm the artwork before production starts.
Q7: Does this low‑grade sealant have long‑term project warranty?
This low-grade silicone sealant comes with standard quality warranty for general construction applications. Extended engineering warranty is not available for facade projects due to product positioning.
Q8: Can I use it for swimming pools and water tanks?
This sealant is suitable for non-pressure decorative fish tanks and landscape glass sealing. It is not designed for swimming pools or pressure-bearing water facilities.
Q9: Can you make custom colors for my projects?
We keep standard colors including clear, white and black in stock. Custom color matching service can be arranged to meet special project requirements.
Q10: Is there any surface preparation requirement before application?
The substrate surface must be fully cleaned and dried. Dust, grease and residual old sealant need to be removed to obtain stable bonding.
