CONCRESEAL® PLASTERING
COVERING WITH DECORATIVE TEXTURE FOR CONCRETE, PREFABRICATED CONSTRUCTION AND RUBBLEWORK. WATERPROOFING RESISTANT TO THE AGGRESSIVENESS OF WATER, PROTECTING CONCRETE REINFORCEMENTS FROM CORROSION.

Description

CONCRESEAL PLASTERING is a mixture of cements and silica carefully controlled together with other mineral aggregates. CONCRESEAL PLASTERING coating has covering, protecting and decorating properties.
It seals and fills the pores and voids in concrete and masonry, becoming part of the surface. It will add approximately 3 to 5 mm in thickness to the surface coatings.

Uses

• For exterior façades as a decorative coat, whether applied by trowel or with a spray gun to substrates of prefabricated constructions made of concrete, mock concrete or roughed in with cement mortar.
• On concrete block partitions it fulfils three functions: it acts as a cover, as waterproofing, and provides a decorative finish.
• To coat concrete with minimum thickness. It protects them from deterioration due to the action of ice and the aggressiveness of water.
• In sewage disposal plants, it provides the concrete with longer life and prevents its reinforcements from corroding thus avoiding their subsequent disintegration.
• As a finished surface for swimming pools. After applying a key coat of MAXSEAL for waterproofing, the surface is finished with a second coat of CONCRESEAL PLASTERING.

Advantages

• Fills and seals holes, voids and honeycombs.
• Actually becomes part of the surface.
• Protects surfaces with a decorative finish.
• Gives a durable waterproof finish.
• Adds uniformity, maintaining architectural details of fluting, vertical lines, decorative mouldings, etc.
• Protects the concrete reinforcements from corrosion.

Application

Surface preparation. The concrete to be coated must be clean, free of paint, efflorescence, foreign materials, grease, form-stripping oils, and dust. Where this is not so, clean by scrubbing with a wire brush or sandblasting. After forms have been stripped, cut all form tie wire back to a depth of 2 cm. Then patch flush with the surrounding area using MAXREST. Cracks should be exposed with a chisel at a depth of at least 2 cm. These should be subsequently sealed with MAXREST.
Plastering of cement mortar should be in the same good condition. Holes and honeycombs should be patched using MAXREST.

Trowel and float finish. A 25 Kg. sack of CONCRESEAL PLASTERING will require 1 litre of MAXCRYL and 3.5 litres of water; power mixing is best. Using the trowel make sure the CONCRESEAL PLASTERING is firmly pressed into all voids and levelled; 20-30 minutes later, a trowel or sponge float must be followed, depending on the texture preferred. A solution of one part of MAXCRYL and three parts of clean water must be used to wet the sponge in the final process of finishing. Do not use only water.
To prevent shadowing of struck or deep masonry joints or areas of unequal absorption apply a light coat of MAXSEAL with MAXCRYL in the mixing water over the entire surface to be treated. After the key coat of MAXSEAL has cured for 7 days, apply a trowel coat of CONCRESEAL PLASTERING.

Sprayed on finish. A 25 Kg. sack of CONCRESEAL PLASTERING will require approximately 2 litres of MAXCRYL and 4.5 litres of water. Mix the material adequately and uniformly. Power mixing is best.
Previously dampen the surface and spray on one coat of CONCRESEAL PLASTERING taking an area of 6 m2 or 8 m2, to fill holes, pores, etc., float or brush out the first spray coat and afterwards start the second spray application maintaining the same distance from the surface. Double back over the surface with a light even spray application, or additional applications as needed to provide a uniform texture.
The quantity of CONCRESEAL PLASTERING depends on roughness of formwork and surface.
For guidance CONCRESEAL PLASTERING application requires approximately 2.5 to 6 Kg/m2 .

Curing

Surface curing is not necessary except under extremely windy or hot conditions and too rapid drying occurs. In the case of using a special colour, do not cure until after 12 hours, using clean water, otherwise a colour variation could occur.

Special instructions

Temperatures. This material should not be applied to walls that are frozen or covered with ice.
You shouldn't work when the temperature is below 5º C. If frost is expected within 12 hours of applying the material, the work should not be carried out.
Follow the instructions below:
Cold weather: Do not make the surface too wet.
Warm or windy weather: Wet the wall several times before applying the material.
Afterwards, dampen the wall slightly using the spray gun so as to allow for a better curing process of the CONCRESEAL PLASTERING.

Caution

CONCRESEAL PLASTERING is made up of an abrasive compound. It is not toxic but care should be taken while mixing and applying it, not to let it come into contact with the hands. Rubber gloves should be worn for protection. If it splashes in the eyes, rinse well with clean water; do not rub. If irritation persists, consult a doctor.
