MasterSeal 501 | Penetrating waterproofing for concrete

Rigid penetrating waterproofing with an armor layer for concrete floors

Description

Characteristics

Application

MasterSeal 501 | This is a capillary-crystalline waterproofing material, cement-based, penetrating action.

Consumption: 2.00 kg/m² (2 coats).
The material is applied to the surface of concrete in old and new structures , with negative and positive water pressure.
With MASTERSIAL 501, it is possible to achieve a final, effective result in cases where there are problems such as leakage and water permeability on new and old surfaces, on concrete or in concrete structures.

Used inside and outside;
Easy to prepare and use;
Long term of operation;
It is used both on vertical and on horizontal surfaces;
The use of materials ensures the creation of a complete and permanent waterproofing system, since, after application, the materials become an integral part of the building structure on which they are applied.

The active chemical reagents that got into the building structure do not decompose, do not flow out and are not washed out of it;
Materials protect the structure of concrete and reinforcing reinforcement from the impact and ingress of corrosive substances contained in water;
The crystallization reaction begins at the moment of contact of materials with water, providing long-term additional protection;
The materials are effectively resistant to water pressure, both from the outside and from the inside, of the treated building structures;
The material is non-toxic.

Material structure Masterseal 501	Consists of mineral fillers, polymer additives and cement
Color	Grey
Surface temperature	from +5°С to +30°С
Operating range	The material penetrates the concrete structure and works in the same way as concrete
Settling time of freshly prepared solution	3-5 minutes
Working time with freshly prepared solution	20 minutes

As with all coating systems, base preparation is of paramount importance;
It is recommended that any residue be thoroughly cleaned of machine oils, grease, dust, vulcanization products, molding chemicals and all other adhesion impairing contaminants;
It is recommended to remove dirt with a light jet of air or water;
For small areas when cleaning, it is possible to use a metal brush;
Loose concrete, it is recommended to remove it before the appearance of sound concrete and restore it with a repair compound, Emaco S 88 C;
The day before application, the surface should be saturated with water, the application should be carried out on a damp surface.

Always add water to MASTERSEAL 501 - not in reverse order;
Mix 1 part water with 2.25 to 2.5 parts MASTERSEAL powder by volume.
MASTERSEAL 501 is poured into a clean bucket, water is slowly added and mixed until a homogeneous solution is obtained, without lumps, for 3-5 minutes with a mixer at 400-600 rpm;
The solution should be allowed to settle for 3-5 minutes and mixed again for 30 seconds to fully prepare the solution;
Do not add additional water after initial mixing is complete.

The concrete base is moistened with clean water to the extent that the moisture becomes visible, but no accumulation of water forms;
The material is applied with a short hair brush;
It is recommended to apply the material with a thickness of two covering layers, at right angles to the surface to be applied;
Apply a second coat over the first after 3-4 hours (depending on ambient temperature);
Detailed information on suitable equipment can be obtained from the technical service of BASF CC Central Asia.

MASTERSEAL 501 must be protected from rapid drying and must be constantly moisturized for 5-7 days;
Components of materials for the care of concrete surfaces, not suitable for use in conjunction with the application technology of the material system of the MASTERSEAL 501 series;
Protect the material from weathering, weathering, sunlight, freezing for a minimum period of 5-7 days;
Reservoirs and other reservoirs containing water can be filled with water 24 hours after application of the MASTERSEAL 501 series, as the growth of insoluble crystals of active chemicals is accelerated by water pressure.

The ambient temperature should not be lower than +5°С and higher than +30°С;
Do not apply the material in rainy and windy weather;
MASTERSEAL 501 applied at 23°C becomes water resistant after 7 days;
When applied to external surfaces, measures must be taken to protect the surface from frost, rain, sun for 24 hours;
Mix only the amount of MASTERSEAL material that you can use immediately within 20 minutes.

Immediately after completion of work, it is recommended to clean the equipment and tools involved in the work.

20 kg. Craft bags.

It is recommended to store the material away from sunlight, in a state raised above the ground on pallets, protected from precipitation and moisture;
Avoid intensive compaction when storing material;
The material has a shelf life of 6 months when stored in tightly closed, original packaging.

When using the material, you need to use overalls, goggles and gloves;
Do not allow the material to come into contact with the skin, in case of contact, wash off with plenty of water using hygiene products.
