Superior Alkalinity Control
Concrete naturally contains alkaline substances. Without proper sealing, these can migrate upward, causing topcoat failure and discoloration. Our high-efficiency anti-alkali formula creates an effective barrier, preventing alkaline seepage and protecting your finish coats.
Professional Adhesion Strength
We've engineered special functional groups into the formula. These create powerful molecular bonds with your concrete substrate, stabilizing even challenging base layers.

Mixing
Stir completely some time recently utilize. If weakening is essential, include no more than 5% clean water for roller or brush application.
Application
Apply one or two coats depending on substrate condition. For extremely compromised surfaces, a moment coat guarantees total fixing. Utilize roller, brush, or high-pressure airless splash equipment.
Environmental Conditions
Apply when temperature is between 5-35℃ and relative stickiness is underneath 85%. Maintain a strategic distance from application amid rain or when rain is estimate inside 24 hours.
Frequently Asked Questions
How does this sealer compare to oil-based alternatives?
Water-based sealers offer critical focal points. They're non-hazardous for shipping, contain negligible odor, dry quicker, and give comparable or prevalent execution. Furthermore, cleanup requires as it were water, not chemical solvents.
Can I utilize this on outside concrete walls?
This preliminary is optimized for insides applications. For outside ventures, if you don't mind contact our specialized group for fitting item recommendations.
How much sealer do I require for my project?
Calculate your divider range in square meters, at that point partition by 10-12 to decide kilograms required per coat. For two-coat applications, twofold this sum. We prescribe requesting 10-15% additional for squander and retention variations.
Will this work on exceptionally fine or chalky concrete?
Yes, this is precisely where our item exceeds expectations. The nano-sized particles enter profound into compromised surfaces, authoritative free particles and making a solidified base layer.
What's the rack life?
When put away legitimately in fixed holders at 5-35℃, rack life is 12 months from fabricating date.
Do you offer custom bundling or private labeling?
Absolutely. Chenyang gives OEM and ODM administrations counting custom bundling, private labeling, and equation optimization for particular advertise prerequisites. Least arrange amounts apply.
