NORDECAL FORTE GEL

Descaling acid gel

Description

NORDECAL FORTE GEL is an acid descaling detergent gel. The product contains hydrochloric acid and is therefore highly effective against mineral-based deposits (lime and cement) that are difficult to remove using descalers based on other acids.

Usage field

NORDECAL FORTE GEL is used to:

  • permanently remove laitance and any excess liquid mortar, cementitious grout, mortar and skim coating from floors (such as terracotta floors, ceramic, stoneware and clinker) and vertical building surfaces (brick walls, concrete walls,...);
  • prepare new or old concrete floors (after removal-if any-of pre-existing treatments), for the application of CEM-O-LUX.

Generally, this product is non-aggressive and does not attack the surface, however a preliminary test should always be done on a small and preferably not exposed section of the surface to be cleaned in order to verify its chemical resistance.

NORDECAL FORTE GEL contains hydrochloric acid which can give rise to corrosive mists: not recommended for use in environments furnished with steel furniture or steel furnishing elements or steel home appliances (unless it is stainless steel AISI 316L).

Packaging

1 liter PE bottle, 5 and 25 liters PE tanks.

Application

(1) When used as a general purpose descaler

On tiled floors:

  • pour and spread NORDECAL FORTE GEL, either undiluted or diluted 1:1 with water, on an approx. 12-15 square meters sections of the floor one at a time;
  • vigorously brush using a scrubbing brush or a Scotch-Brite®(or better, with a monobrush fitted with an appropriate disks);
  • NORDECAL FORTE GEL will react within a few minutes dissolving all residues and to turn into a thick mush;
  • then remove the all thing using a wet vacuum cleaner or a mop;
  • then rinse abundantly the treated area;
  • the most stubborn of cement residues must be removed with a triangular spatula.

On new ceramic floors:

  • dilute 1 part of NORDECAL FORTE GEL with 4÷5 parts water;
  • test a small section of the floor for resistance to acidity;
  • pour and distribute the product on the floor, then wash brushing with care all the encrusted sides using a Scotch-Brite® abrasive sponge or a scrubbing brush;
  • rinse thoroughly with water after the acid wash.

New clinker or stoneware floors:

  • dilute 1 part of NORDECAL FORTE GEL with 1÷2 parts water and proceed using the method described in the above step.

On exposed bricks:

  • soak an abrasive sponge like Scotch-Brite® in the undiluted NORDECAL FORTE GEL and rub the area to be treated;
  • allow a few minutes for product to take effect;
  • rinse thoroughly and abundantly.

 

(2) When used after cementitious tiles grouting:

  • allow sufficient time for the tile grout to fully cure (see the Technical Data Sheet);
  • dilute 1 part NORDECAL FORTE GEL with 6÷7 parts water;
  • use the product to remove all grouting residues from the tiled surface (either floor or wall) using an abrasive sponge like a Scotch-Brite® or a mop but only on the encrusted parts.

 

(3) When used as a descaling cleaner to prepare floors before the CEM-O-LUX cycle

On old concrete floors:

  • preliminary operation for control of the area see the data sheet of CEM-O-LUX;
  • de-dusted surface;
  • NORDECAL FORTE GEL diluted with water in proportions of between 1:2 and 1:8. These dilutions of the diluted product still has thixotropic properties.
