Miracote Aqua-Blok XL: Miracote Block 5 Gallon

Miracote Aqua-Blok XL is a clear, single component, odorless, water-based, penetrating colloidal silicate liquid primer that integrally waterproofs concrete, mortar and other cementitious materials. Based on scientifically superior inorganic mineral waterproofing technology, Aqua-Blok XL penetrates deep into the capillary structure of concrete and mortar to permanently enhance physical properties and the dynamics of waterproofing performance. Exhibiting highly reactive and hydrophilic properties, Aqua-Blok XL quickly migrates through waterways and capillary tracts to chemically convert free water-soluble calcium hydroxide into a dense crystalline network of insoluble calcium silicate hydrate gel within the concrete pore structure. This conversion process has been found to purge unwanted chlorides and other contaminants from the concrete matrix. As determined by the U.S. Bureau of Reclamation M-82 Standard Protocol to Evaluate the Mitigation of Corrosion Technologies in Concrete Repair, MiraPrime Aqua-Blok XL substantially reduced corrosion at a 95% Confidence Limit.

???? Always install a minimum 4’ x 4’ on-site mock up to verify actual coverage rates, and for approval of acceptable color, texture, finish, adhesion, and any other critical requirement acceptable to the owner prior to proceeding with the installation.

???? Protect materials from excessive heat and cold, and pre-condition to room temperature as necessary.
???? Measure surface and ambient temperatures to ensure the material is only applied when temperatures are 40°F (4.5°C) and rising during placement and cure time.

???? When applying Aqua-Blok XL to concrete exhibiting excessive hydrostatic activity, as evidenced by saturated and weeping surfaces, vacuum and dry surfaces and immediately follow up the first application with a second and third application, as required.

???? Depending on climatic conditions, density of the treated concrete, and potential for purging of chlorides and other entrapped contaminants, Aqua-Blok XL is required to cure for 1-7 days prior to the application of surface applied materials.

???? Prior to applying subsequent surface coatings any contaminants purged from the concrete must be removed by vacuum and cleaning.
???? The proper application of this product is the sole responsibility of the end user. Job site visits by Miracote representatives are only for observation and making recommendations, and does not assume any liability for supervision or quality control.


???? Protect Miracote Aqua-Blok XL treated surface from rain for a minimum of two hours after final application.
???? Protect glass, plant life, aluminum, ceramics, glazed tile, wood vehicles from contact by overspray. Remove with water immediately.

???? Can etch glass, avoid contact and rinse glass immediately.
???? Do not apply if minimum/maximum ambient and substrate temperatures are 40°F (4.5°C) and above 100°F (37.8°C) 24 hours prior to and following application.
???? Concrete surface sealers and polymer-modified mixes will inhibit penetration and function of MiraPrime Aqua-Blok XL.
???? Rebound-laden shotcrete and gunite structures will be deficient in cementitious content to form a proper chemical reaction and full waterproofing potential.
