DESCRIPTION
CemGuard is a two-component, polymer-modified, cementitious waterproofing and protective hightest mortar for concrete. It is slightly flexible to tolerate fine cracks and suitable in both interior and exterior applications.
ADVANTAGES
Never apply > 2mm total thickness which will cause delamination
Can be applied on damp substrates.
No application of primer is needed on the receiving substrate.
Premixed to ensure high consistent quality.
Non-toxic and odourless, highly suitable for confined areas
CemGuard is able to withstand foot traffic when cured.
Premixed to ensure high consistent quality.
Non-toxic and odour less.
COMPLIED STANDARD
• ASTM D412
• BS EN 14891
WHERE TO USE
• Waterproofing and protection of concrete structures, renders and cementitious screeds.
• Waterproofing of concrete basins used for containing water.
•Waterproofing bathrooms, showers, balconies, terraces, swimming pools, etc. before laying ceramic tile finishes.
•Waterproofing of plasterboard, render or cementitious surfaces, lightweight cement blocks and marine-grade plywood.
• Flexible smoothing layer for light-sectioned concrete structures, including those subjected to minor deformation when under load (e.g. pre-cast panels).
• Protection of renders or concrete with cracks caused by shrinkage, against the infiltration of water and aggressive atmospheric elements.
• Protection, against the penetration of carbon dioxide, of concrete pillars beams, and structures with an insufficient layer of concrete covering on the reinforcement rods.
METHOD OF USE
Surface Preparation
Ensure all surface where CemGuard is to be applied must be free from oil, grease, wax and loose materials. For area where water absorbent is expected to be high, damp surface before applying CemGuard.
Mingxing
Pour Part B (liquid component) into a clean container. Add Part A (powder component) slowly that allows mixing with a low-speed mechanical (350-450 rpm) until CemGuard is a homogeneous paste and is free of lumps.
Application
CemGuard can be applied with a stiff brush, a roller and can be trowelled on. For trowel application, the substrate should be leveled and free of any undulation (e.g. Potholes). During application ensure that air is not entrapped within the membrane. After application of the first coat of CemGuard, allow it to cure for about an hour and ensure that the first coat has initial set before applying the second coat. Thickness of each coat can be between 1mm – 2mm.
Curing
• Natural air curing is sufficient
• Paint, tiling, mortar or render should be applied after 2 days curing
• Water ponding test can be carried out after 2- 4 days curing
Cleaning
CemGuard can be removed from tools and equipment with clean water. When CemGuard is cured, it can only be removed mechanically.
Handling
CemGuard should be stored in a dry place under shade, free from moisture contact. CemGuard is non-hazardous. During windy conditions, wear a filter mask to avoid inhaling powder component from part A. Remove splashes from skin with water. in case of eye contact, wash with plenty of water. If irritation persists, seek immediate medical attention.
