Substrate preparation

The substrate must be carefully prepared in advance to ensure maximum adhesion performance and system durability. Complete removal of degraded, loose, or contaminated concrete is necessary until sound and resistant substrate is reached. Surfaces must be appropriately roughened by mechanical scarification, sandblasting, or preferably high-pressure hydro-scarification to obtain adequate roughness for mortar anchoring. Any exposed reinforcement must be fully exposed, cleaned of rust by brushing or sandblasting to clean metal grade and, if necessary, treated with Drykos^® Renov Col passivator, depending on exposure conditions and intervention timing.
Before application, the substrate must be saturated with water to a “saturated surface dry (SSD)” condition, carefully removing any surface ponding. Rigid, watertight, and perfectly sealed formwork must be prepared, suitable for containing the casting pressure and preventing mortar leakage. Formwork surfaces must be treated with suitable release agents to facilitate removal operations.

Product preparation

Drykos^® Renov Col is a single-component mortar to be mixed with clean water until a fluid, homogeneous, lump-free mixture suitable for pouring is obtained. Pour approximately 2/3 of the required mixing water into the mixer, then gradually add the powder product under continuous agitation. Subsequently complete with the remaining water until the desired consistency is achieved. Mixing must be performed using a concrete mixer or low-speed mechanical agitator for a minimum of 3-5 minutes until a perfectly uniform mixture is obtained, free of agglomerates and with adequate fluidity.
The water/product ratio is approximately 10-12% by weight, about 2.5-3 liters per 25 kg bag, and must be strictly observed to avoid segregation, bleeding, or reduction in mechanical performance. For high-thickness filling, the addition of selected aggregates (such as clean gravel of appropriate grain size) may be considered according to design specifications.
It is recommended to prepare only the amount of material that can be applied within the workability time.

Application

Drykos^® Renov Col must be applied by continuous pouring or pumping inside previously prepared and sealed formwork. Casting should preferably be performed from one side of the formwork to promote uniform advancement of the mortar and progressive air expulsion, avoiding the formation of voids, cavities, or discontinuities. Thanks to its rheoplastic and self-compacting nature, the product can completely fill even complex volumes and congested sections, ensuring perfect reinforcement encasement and high adhesion to the substrate.
The use of vibration should be limited to what is strictly necessary: excessive vibration can compromise mixture stability and final casting quality. During placement, it is essential to maintain operational continuity, avoiding interruptions that could generate cold joints. In case of casting resumptions, the surface must be appropriately prepared before subsequent application. For high thicknesses, casting can be performed in multiple phases or the use of supplementary aggregates may be considered, depending on project specifications.
During application, avoid unfavorable environmental conditions such as high temperatures, strong wind, or direct radiation, which can accelerate water evaporation and compromise proper material curing. At the end of casting, adequate curing must be ensured by protection with sheeting, curing compounds, or water misting for at least 24-48 hours to prevent plastic shrinkage phenomena and promote optimal development of mechanical strength.

Cleaning of tools

Clean tools with water immediately after use. Hardened product can only be removed mechanically.
