Characteristics

SELAMIX can be applied to any rustic masonry surface that does not present structural problems or is not subject to cracking. It has resistance to negative and positive pressure, and may or may not have the presence of moisture or groundwater. Easy to apply product, just mixing water in the correct proportion, with great yield per m². After application, SELAMIX becomes part of the surface. Accepts any type of coating when applied horizontally. For vertical coating and finishing, a technical evaluation of the project must be carried out to verify that the product meets the necessary requirements. In reservoirs it provides odorless and crystalline water.

Use

SELAMIX can be applied to water tanks made of bricks, masonry, concrete blocks, stone, fiber cement water tanks, cisterns, single-storey masonry pools, single-storey or aerial flower beds, marquees, grease traps, basements, elevator shafts, tunnels, retaining walls, pits, manure pits and small concrete slabs without subfloor, baldrame beams, masonry walls, bathroom stalls, etc.

Composition

Portland cement, mineral fillers and special additives.

Technical characteristics

Appearance: powder

Color: white and gray

Mix open time: 60 minutes

Performance

Approximate average consumption of 1kg/m²/coat.

For moisture prevention, use 3 coats of SELAMIX.

In reservoirs, cisterns, swimming pools and other forms of water storage, use 4 coats of SELAMIX.

Storage

It should be kept at room temperature, in a dry and ventilated place, on pallets.

Shelf life

In its original unbroken packaging, it has a shelf life of 24 months.

Packaging

Plastic packaging of 5 kg and 18 kg.Plastic package with 5 kg or 18 kg. 5 kg packages are supplied in 6-pack bales.

Surface preparation

Calculate the surface to be waterproofed. Clean the surface properly, completely removing loose particles or concrete burrs. In areas soiled with silt or old concrete, wash well with a brush or high pressure washer. On calfined surfaces, it is necessary to remove this layer in 100% of the area. If there is rising damp, remove all the plaster at a height of 1.2 m from the baldrame, apply SELAMIX on the bricks and plaster again, leaving a distance of 1 cm from the floor and fill with SELAMIX. Do not apply SELAMIX directly on materials with a surface or layer that contain petroleum derivatives, such as: paints, varnishes, asphalt emulsion, asphalt blanket, glue, resin-based waterproofing agents and others, in which case they must be removed 100% of the way. area. The surface where PVA-based glue will be used must be screed after application of SELAMIX. On slabs and floors, if there are cracks, cracks, expansion joints, first repair with ELIMINETRINCA. Never apply SELAMIX on slabs that have subfloor or cement cream, which must be removed, applying SELAMIX directly on the concrete of the slab. In concrete tanks and reservoirs, before applying the waterproofing system, perform the water load test for at least 72 hours to accommodate the structure and check for any cracks or fissures that may occur in the total load to correct them. .

Product preparation

Dilute the product in approximately 40% of water. Mix the product with a mechanical stirrer for 3 to 5 minutes or with a spatula for 8 to 10 minutes to obtain a dense, lump-free liquid mass. After mixing, let the dough rest for 15 minutes and before starting the application, beat again, after this period, beat the dough every 10 minutes. Prepare only the amount to be used in each coat, the remainder cannot be used for the next coat. For application in large areas, prepare only the amount of product that you can apply in a maximum period of one hour.

Application

Wet the surface well with water, avoiding puddles. Apply SELAMIX using a brush, brush or fur broom, passing 8 to 10 times in the same place in an elongated way to close the pores and better compact the product. Subsequent coats should be done in the same way as the first, wetting the area and running the broom repeatedly over the product. Do not apply on surfaces with a temperature above 22ºC. SELAMIX must be applied in cross coats with an interval of 6 hours between applications in normal conditions and 24 hours in humid places or subject to trampling during application, or wait until the product has surface resistance. On slabs, keep the applied area in wet curing during the coats and 48 hours after the end of the last coat, spraying water with a high pressure washer or covering the surface with plastic tarpaulin. Drying after the last coat is 48 hours of good weather and full cure is 28 days. The prepared product should be applied in a maximum of 1 hour. In areas exposed to the sun (ultraviolet rays), and areas subject to traffic, after 5 days of applying SELAMIX, a mechanical protection must be carried out, with a subfloor, throughout the area. In water reservoirs for human or animal consumption, wash the surface three times, using water and a multipurpose brush, and discard the first load of water. In fish ponds, check the pH of the water before use.

Cleaning

Equipment and tools can be cleaned with water as long as the product is not dry. After drying, clean the tools mechanically.
