CARBO STUCCO

Epoxy Skim Coat
for FRP Systems

Description

CARBO STUCCO is a two component product consisting of:

  • Component A: a mixture of liquid epoxy prepolymers, fillers and additives;
  • Component B: copolymerization amine.
Usage field

CARBO STUCCO is used to prepare the surfaces scheduled to be treated with either VETROFIL or CARBOFIL FRP systems and, in particular during the surface skim coating (needed to obtain a sufficient flatness for laying the FRP systems).

Application

Surface Preparation:

  • the substrate must be carefully checked to ensure it is a suitable and structurally sound base and, depending on the existing surface conditions, the type of preparation to be done must be chosen.

Specific Preparation:

  • apply a coat of CARBO FONDO to the surface to be treated;
  • within minutes or at most within 24 hours, apply a coat of CARBO STUCCO with a spatula if the surface requires a levelling skim coat;
  • proceed with the laying of either CARBOFILL or VETROFIL and impregnate until saturation with CARBO BASE.

Product Preparation:

  • poor CARBO STUCCO component B into component A stir well with a professional helical blade mixer for about 2-3 minutes, until the mixture is homogeneous.
  • The amount of product (A + B) to be prepared must be calibrated each time according to room temperature, in order to be able to use it all before pot life expires.
  • In any case, the amount of component A and component B shall be weighed with a scale.

Coverage: according to the roughness of the substrate, 1÷3 kg/m2.

Warning and informations
  • In cold weather (8÷16°C) the product exhibits a higher viscosity.
  • In hot weather (26÷30°C) the reaction speed will go faster and the system can reach the gel phase very quickly.
  • Apply further layers the following day, after a maximum of 48 hours.
  • Refer to the Material Safety Data Sheet (MSDS) before use.
Preservation

24 months in original packaging, in a dry area out of direct sunlight, between +5°C and +35°C
