Cement Modifier: Primer of Water-Based Waterproofing Works
Obaproof® CM-700WP Ready Mix cement modifier is a copolymer of styrene, modified from MMA and butadiene, Obaproof® CM-700WP Ready Mix is environmentally friendly with low VOC content. When added into cement and mortar, it permeates into the gaps between the cement and aggregate, filling the pores to create a finer texture in cement and mortar. This further enhances the waterproofing and durability of the cement and mortar.
When plastered onto the surface of engineering cement, it adheres firmly to the concrete and protects concrete from the osmosis of water contents, preventing reinforcement corrosion and cement aging.
Application on the joint between new and old cement can cure the light powder dust on the construction surfaces, enabling better film adhesion between the waterproof layer and construction surface, thereby enhancing the adhesive strength of the waterproof material.

Uses
Obaproof CM-700wp is a higher strength floor screed and improved flexibility and resistance to cracking. Obaproof CM-700WP can also be used as a bonding agent between new and old concrete.
Surface Preparation
All the surfaces must be clean, free from grease, oil, laitance, and remove all the dirt and contaminants, which might affect adhesion.
The impurities outside the structure body should be cleaned thoroughly.
Application
Use Obaproof CM-700WP for quality modification of cement and mortar. In the hydrolysis medium, the emulsion is a stable dispersed polymer. When used, this emulsion improves the combined characteristic of the softness with mortar. Add Obaproof CM-700WP to the mortar, which first softens, then cures, and finally becomes hard, wear-resistant, and durable with anti-bending properties.
Bonding Agent/Primer:
Dilute 1 part of Obaproof CM-700wp permeable primer with 3 parts of clean water, then plaster directly to the surface to be waterproofed to improve bonding.

Safety
Impervious gloves and barrier cream should be used when handling these products. Eye protection should be worn, In case of contact with eyes, wash thoroughly with plenty of water and seek medical advice if symptoms persist. If contact with skin occurs, it must be removed before curing takes place. Wash off with an industrial skin clearer followed by plenty of soap and water. Do not use solvent.
