Applications
Forms a waterproofing and protective coating for cement-based surfaces, decorative fired bricks, water-paint surfaces, etc. BestSeal AC404 effectively blocks water ingress from capillary penetration or tiny cracks, while preventing chemical, biological or mechanical-abrasion attack to reduce chalking, dusting, soiling, mold and algae, etc. throughout service under harsh weather. BestSeal AC404 can be applied directly onto concrete, cement render, fiber-cement cladding panels, etc., for factories, warehouses, parking garages, gutters, rooftops, enclosure walls, etc.
Mixed directly into water paint to improve the paint film's quality, waterproofing, dust resistance and adhesion, etc.

Application instruction
Surface preparation:
The surface to be waterproofed must be dry and free of dust, oil/grease or similar materials.
Burrs or spilled cement-mortar patches, etc. must be chipped off and thoroughly cleaned.
For highly absorbent and friable surfaces, up to 10% clean water may be added to BestSeal AC404 and stirred well before application.
For flat, dense surfaces with medium roughness, no dilution is needed, but at least 2 coats of BestSeal AC404 must be applied after the surface has been cleaned by suitable means.
At least two coats of BestSeal AC404 should be applied to ensure absolute waterproofing.
When using BestSeal AC404 mixed directly into water paint, add 15 - 20% by weight of the paint for application.
Mixing:
The product is pre-mixed; stir or shake it well before use.
Application:
Use a brush, short-nap roller or pressure spray gun to apply the product. For high waterproofing effectiveness, ensure the product is distributed evenly with no missed areas.
Do not let the product pond on the surface.
Notes:
When applying the next coat, work in a diagonal or perpendicular direction relative to the previous coat.
Cleaning:
Use water and soap to clean tools immediately after use and before the product cures.
Safety guidance:
BestSeal AC404 may cause irritation to sensitive skin on prolonged contact. Wear a mask, gloves and safety goggles when using the product.
If splashed into the eyes, nose or mouth, rinse immediately with plenty of clean water several times before going to the nearest medical facility for timely and proper treatment.
Dispose of excess product at locations designated by local regulations.
