Maxseal Flex:  
 

MAXSEAL FLEX is a coating with flexible and waterproofing properties that adheres to practically every surface such as concrete, natural and artificial stone, mortar plasters, bricks, concrete blocks, etc. subjected to both positive or negative high water pressure. Waterproof coating that adheres to common substrates in construction such as concrete, natural and artificial stone, traditional mortar plasters, bricks, concrete blocks. Once applied and cured, MAXSEAL FLEX provides a non-toxic, flexible and waterproof coating that adheres to those common substrates in construction such as concrete, natural and artificial stone, traditional mortar plasters, bricks, concrete blocks.

 

Description

 

MAXSEAL FLEX is a two component product: Component A is a mortar based on a mixture of special cements, additives and well-graded fillers and Component B is a liquid based on special synthetic resin. MAXSEAL FLEX is a coating with flexible and waterproofing properties that adheres to practically every surface such as concrete, natural and artificial stone, mortar plasters, bricks, concrete blocks, etc.

Once applied and cured, MAXSEAL FLEX provides a non-toxic, flexible and waterproof coating that adheres to those common substrates in construction such as concrete, natural and artificial stone, traditional mortar plasters, bricks, concrete blocks.

 

Application Fields

 

Waterproofing and protection of water retaining structures, such as drinking water tanks, reservoirs, water mains and swimming pools. Waterproofing of below-grade structures like basements, retaining walls, foundations, tunnels, galleries subjected to both positive or negative high water pressure.

Internal and external waterproofing and protection of new and old buildings, facades against dampness, rain, pollution and aggressive environments.

Waterproofing and protection of concrete against carbonation, freeze-thaw cycles, de-icing salts in highways and chlorine penetration in public works, irrigation channels, dams, retaining walls and water treatment plants, bridges, etc.

Tile fixing and waterproofing of bathrooms, kitchens and other wet rooms in hotels, hospitals, offices and residential buildings, also suitable for exterior applications. Waterproofing of jardinieres, terraces and balconies under the pavement.

 

Advantages

 

Provides a fully-flexible coating which ensures complete waterproofing even in the most severe conditions, as high negative water pressure.

Covers shrinkage and hairline cracks of the concrete.

Acts as an anti-fracture membrane between the substrate and other finishing coats if applied.

Excellent protection for concrete, being both a CO2 and chlorine (Cl-) barrier and thereby preventing carbonation and electrochemical corrosion.

Permeable to water vapour, allows the substrate to breathe.

Resistant to abrasion and UV rays.

Withstands atmospheric pollution, corrosive effects of salt water and de-icing salts and freeze/thaw cycles.

Resists hydrostatic negative pressure from ground water when used for underground interior applications.

Excellent adhesion and easy to use. Does not require bonding agents and can be applied on wet surfaces

Non-toxic and chloride-free. Suitable for contact with potable water.

Longer lasting that other coatings, avoiding maintenance costs.

Environmentally friendly

Specially recommended to complement other products of DRIZORO system as

Application instructions

Treating efflorescence and salts for adhesion of Maxseal Flex to a masonry substrate

 

Preparation of the surface.

 

The surface to be coated must be sound, clean, free of all traces of paint, dust, grease, efflorescence, loose particles, gypsum, plaster and mould release compounds. Recommended cleaning methods are high pressure water cleaning and sandblasting. Other percussive methods are not recommended.

Any damage or concrete defect should be repaired in advance. Patch all holes, voids and honeycombs. Cracks opened to approximately 2 cm. in depth. Exposed steel bars must be cleaned and patched with Maxrest up to 1 cm. minimum thickness. If it is needed, treat steel bars with Maxrest slurry coat.

Mixing.

 

MAXSEAL FLEX is supplied as two pre-weighed components. Pour the resin, component A, into a clean container and add the powder gradually, component B, while mixing with a low speed mixing drill (400 - 600 rpm). Mix until a homogeneous mixture free of lumps is achieved. Do not add water and keep liquid/powder ratio as the package supplied. Depending on existing temperature and R.H. climate conditions, pot life expected will be between 30 minutes and one hour.

Application. MAXSEAL FLEX is applied with a fibre type brush or broom such as MAXBRUSH or MAXBROOM respectively, or by trowel when a smooth finish is required. For large areas MAXSEAL FLEX can also be sprayed, being the recommended nozzle size 3-4 mm and spraying pressure between 3,5 and 5,0 bar. When sprayed, it is recommended to finish the fresh coat with a broom to make sure that the hole surface is covered completely.

Apply two coats, using 1 - 1,5 kg/m2 of MAXSEAL FLEX per coat and allow a minimum of 16 hours and a maximum of 3 days between applications. Prior to application thoroughly wash down and saturate the surface, but do not leave free standing water. Thickness per layer should be 1 mm. approximately, thereby being important to avoid very thin application or, on the opposite, a much thicker one.

In those areas such as fissures, concrete joints and active cracks, once repaired and sealed, MAXSEAL FLEX will be applied with a fibre glass mesh of 40 g/m2. Place the mesh on a first coat of MAXSEAL FLEX, with at least 20 cm wide of strip, and then apply a second coat of MAXSEAL FLEX.

 

Application conditions.

 

Optimum application temperature is between 10 -25 C. Do not apply below 5 C or if lower temperatures are expected within the following 24 hours after application. Do not apply on frozen surfaces or if rain is expected 24 hours after application.

Protect against quick drying by winds and high temperatures, by fog-spraying with water for two hours after application.

Curing. Curing time required to put the product into service or to immerse it in water will depend on temperature and relative humidity conditions on site. Conditions in the range of 20 C and 50% R.H will require a minimum of 14 days to ensure that the product has cured enough to be in permanent contact with water. Applications made at lower temperatures or sites without ventilation will require longer curing periods. Wash the surface of MAXSEAL FLEX with water before putting into service in permanent contact with water.

Cleaning. All the tools must be cleaned with water after use. Once it cures can only be removed by mechanical methods

 

Mixing Maxseal Flex

MAXSEAL FLEX is supplied as two pre-weighted components. Pour powder, component B, into a pail containing the resin, component A, mix with a low speed mixing drill until a homogeneous mixture is achieved. Do not add water.

Apply two coats, using 1 - 1,5 Kg/m3/4 of maxseal flex per coat and allow a minimum of 16 hours and a maximum of 3 days between applications. It takes 7 days for the product to cure completely. It is then ready to withstand permanent contact with water. The pot-life of the mixture depends on the temperature, from 30 minutes to 2 hours.

 

IT IS THE RESPONSIBLITY of the applicator to determine whether a structure contains any form of efflorescence PRIOR TO APPLICATION . Any traces of efflorescence in negative waterproofing should be high pressure water blasted and SILOXANE CLEAR introduced with two coats of MAXSEAL FLEX.

 

Consumption

MAXSEAL FLEX is applied in two coats of 1 -1,5 kg/m2 approximately per coat, achieving a total consumption of 2 - 3 kg/m2.This consumption must be kept to ensure the performances.

 

Surface Preparation

 

The surface to be coated must be sound, clean, free of all traces of paint, dust, grease, efflorescence, loose particles, form-stripping oils, gypsum plaster and curing compounds.

Spilled concrete should be cut to approximately 2 cm depth. Any exposed reinforcement cleaned and cut under. Apply a slurry coat of Maxrest and then shape up with Maxrest mortar.

Similarly patch all holes, voids and honeycombs with Maxrest

Thoroughly wash down and saturate surface with water, but leave no free standing water.

 

Tools

 

MAXSEAL FLEX is applied with a fiber type brush such as maxbrush, broom or roller. For large areas maxseal flex can also be power sprayed. It is recommended that the first coat be applied by brush in order to cover the surface completely. On horizontal surfaces maxseal flex can also be spread using a trowel. Use water to clean tools after the work is finished.

 

Storage

 

Twelve months in its original unopened packaging, in a dry and covered place protected from frost, with temperatures above 5 C.

Packaging

MAXSEAL FLEX is supplied in grey and white colour, both available in standard and smooth textures. Pigmented version MAXSEAL FLEX DECOR is available in light colours by especial request.
