Preparation & Installation Procedure Technical Memo
Q. Can Moisture-Fix be applied to wet surfaces?
A. Yes, providing there is no free or pooled water. This means that you can pressure clean and still apply after the free water isgone.
Q. What coverage rate do I get with one litre?
A. Approximately 4m2 per litre, however, some very porous poor quality concretes may require more product to enable the sufficient chemical reaction to achieve total results.
Q. Will one coat be sufficient?
A. Yes in the majority of cases. It may require an additional coat where Hydrostatic Pressure is evident or on old concrete where there is unusually high moisture readings.
Q. Can I install on concrete that is less than 14 days old if I am forced to?
A. Yes, however contact Protect Crete for further information and advice.
Q. Do I have to remove curing membranes?
A. Yes, as you would with any other material and as laid out in the Australian Standards. Surface must have some porosity to allow penetration. Pour a little water on surface to test for porosity.
Q. Does treated concrete require special primers or Prep. before applying floor prep. materials?
A. Generally no, as most leading brands have been successfully applied. Contact Protect Crete or the leading brand Manufacturers for their recommendations. Floor must be sanded and vacuumed to remove all the possibility of alkaline laitance purged, excess dried material or any other contamination.
Q. What is the shelf life and can I reseal the pail for further use in the future?
A. Moisture-Fix has virtually an unlimited shelf life and comes in pails with re-sealable lids fitted with re-sealable and retractable spouts (20 litre only) for easy dispensing. The long shelf life allows for product to kept on hand for convenience and just in case an unexpected moisture job comes up.
Q. Does Moisture-Fix require mixing and special clean up procedures?
A. Moisture-Fix is ready to use, no messy mixing or clean up required. Simply wash with water.
Q. Is Moisture-Fix safe to use?
A. Moisture-Fix is totally user and environment friendly, odorless, zero VOC. MSDS sheet available.
Q. What precautions if any should I take?
A. As Moisture-Fix is alkaline, like so many other products commonly used in the building industry such as wet concrete, cement mortar, cleaning chemicals etc. may cause some slight surface etching effect on glass or polished aluminum if allowed to dry before rinsing with water. Best to mask or protect from product drying on the surface. If contact is made wipe off with water and dry with clean cloth.
Q. Will Protect Crete assist with technical training and provide site visits if needed?
A. Yes, Protect Crete will provide service, training and assistance to ensure you of successful installations.
Q. How long do I have to interrupt site access and how long before I can walk on the surface?
A. Normally, the area is trafficable in one hour. Where as most other systems are closed to foot traffic and general site access for 24 hours and in some cases 72 hours.
Q. Will dropping tools etc on the surface damage the moisture proofing ability?
A. Unlike many other products that form a topical type membrane that if perforated, it basically renders the system ineffective, Moisture-Fix penetrates deep inside the concrete matrix and allows drilling, nailing and surface damage to occur without affecting its moisture proofing performance.
Q. Can I apply adhesives and leveling, repair mediums directly to concrete treated with Moisture- Fix?
A. The unique formulation of Moisture-Fix has been specifically designed to moisture proof concrete and at the same time achieve and maintain an approximate 2mm surface porosity to accept acrylic primers etc that are commonly used in the flooring Industry. After the final sanding and vacuuming of Moisture-Fix treated concrete has taken place, you will notice this porosity and the floor is ready to proceed with floor Prep etc. Although, there are many types of adhesives and leveling compounds/repair mediums that are used directly on the prepared surface, if the concrete is very dense ( high quality ) in surface and matrix make up, you would normally have to apply some leveling material to accept water borne hard set type of adhesives to allow moisture dissipation and correct tack times whether our material was used or not. In other words, on this type of concrete, because of the size and molecular shape of our material, it would normally penetrate and complete its purpose and after sanding and vacuuming to remove any contaminants that may have been purged, or some excess material that has dried on the surface, you would be left with the same dense surface you started with, which would require some surface prep as previously mentioned. In other words, it is not all about the effect of our product, but also the original density of the substrate.
As mentioned previously, legally we cannot speak on behalf of other manufacturers and strongly suggest you contact the product manufacturers for their product recommendations for the required purpose, as there is so many different types of adhesives etc manufactured for particular and specific uses.
