MAXSEAL FOUNDATION


A waterproof, cement-based coating for exterior underground concrete and masonry. 

Description:
MAXSEAL FOUNDATION is a cement based product which, with special additives and selected aggregates to provide total waterproofing protection to concrete, bricks and blocks due to its high resistance to aggressive waters. Will seal against positive and negative water pressure.

Uses:
Waterproofing of retaining walls, car parks, basements, elevator pits, below grade ingress of water in foundations. It can also be used as waterproofing layer or barrier against humidity by capillarity on a variety of mortar substrates.

Advantages:
• Good adhesion, it becomes part of the substrate , fills and seals all pores, missing mortar lines etc.
• Must be applied to wet surfaces
• Can be sprayed by airless sprayer (3 to 5mm tip)
• Can be rendered or painted over.
• NOT affected by salts and acids in soil.
• Easy to apply with Drizoro brush.
• Will seal against positive and negative water pressure.

Surface preparation:
To obtain a good bond to concrete or masonry surfaces, it needs to be a medium to high porosity substrate. If low porosity MAXSEAL FLEX should be used. At the wall/floor junction, cut a 2x3 cm. slot, refill it with MAXREST Or MAXPLUG or MAXJOINT ELASTIC.
If honeycombing is present in concrete, patch it with MAXREST. Concrete scaffolding wires or passing rods must be cut and patch with a minimum 1 cm. deep must be made, then patch with MAXREST.

Surface preparation:
The surface to be coated must be sound, clean, free of traces of paint, loose particles, dust, grease, mould release compounds, gypsum, efflorescence. IT IS THE APPLICATORS RESPONSIBILITY to determine the presence of (salt) efflorescence prior to application. Remove efflorescence using EFFLORESCENCE-RID and apply SEALTIGHT to the affected areas to block salt from penetrating.

Important:
Maxseal Foundation can only be applied to a wet surface, NO other primer or OTHER product is required except in areas where salt treatment has been carried out. Apply Maxseal Foundation in these areas while surface is still wet with SEALTIGHT. Concrete and masonry foundation walls subject to extreme pressures and water aggressiveness.

Mixing:
Pour clean water in a bucket and add MAXSEAL FOUNDATION, ratio approx 3.5kg powder to 1 litre of water mix slowly with electric drill (400-600 rpm) obtaining a thick creamy paste. Let material rest for 5 minutes before application. A 25 Kgs. MAXSEAL FOUNDATION bag requires 7-7.5 Itrs. of water.

Application:
Dampen surface with clean water and apply a first MAXSEAL FOUNDATION layer with a 1,5 Kg / m2 load. After 14 to 24 hours curing, dampen the surface again before applying a second layer and must be applied crosswise with a 1 Kg / m2 load (1 to 1.5 mm wet film thickness) During curing, water vapour may condense on the Surface in poorly ventilated areas. Place exhaust fan or heat source to eliminate moisture saturated air. Allow surface to cure for 3 days prior to back filling and 7 days prior to filling structure with water.

Applications tools:
MAXSEAL FOUNDATION is applied by brush, MAXBRUSH or broom to ensure penetration into pores and hollows. Apply at a thickness of approx. 1 mm to form a continuous and even coating, do not extend as paint and apply only in one direction. Second layer must be applied crosswise. After material application, clean brushes with water for further use.

Application temperature:
At summertime temperatures, wet the surface with abundant water to cool surface. If fast drying is observed, water can be mist sprayed 2 hours after the product application. In winter time do not apply at temperatures below 5º C or if lower temperatures are expected within the next 24 hours after the application. It must not be applied on frozen or icy surfaces. Optimal working temperature is between 15 to 28º C. Avoid application when rainfall is expected within the next 4-6 hours further to application.

Packaging:
25 kg bags and 14 kg handipack.

Storage:
One year in its original unopened container in a dry covered place, protected from frost.
