Primer Wet

PRIMER WET

Two component, 100% solids epoxy resin as a primer (for damp conditions)

PRIMER WET is a free solvent resin, low viscosity, applicable in a single layer. It is specially designed to increase adherence of waterproofing systems based on continuous membranes, TECNOCOAT P-2049 pure polyurea membrane and DESMOPOL single polyurethane membrane, even on concrete or mortar substrates with high residual moisture.

Uses

Epoxy resin to use in:

  • concrete or mortar surfaces/supports, with high moisture or water content.

NOTE: call our technical department about the application to other supports or situations

pot life at 23ºC 20 min.
passable at  23 ºC 3~6 hours
repainting range time at 23ºC 3~6 hours
operating temperature 5~35 ºC
maximum support moisture (residual) ±98%

GENERAL FEATURES

  • To apply on porous surfaces such as concrete or mortar.
  • It’s a mixture of a two component, epoxy resin without solvent ( 100% solids content)
  • Removes residual moisture from mortar or concrete type supports up to 98%.
  • It can be applied on porous surfaces: concrete, cement, etc.
  • Respect existing structural joints (not covered with PRIMER WET).
  • Applied by trowel.Consumption is 600 g/m², thickness 350 mic.
  • Do not use with groundwater pressure.

PRESENTATION

Kit metal tins of:
COMPONENT A: 11,95 kg + COMPONENT B: 3,05 kg

EXPIRY

12 months each product at temperatures between 5° C and 35° C, provided it is stored in a dry place. Once the tin has been opened, the product must be used immediately.

APPLICATION METHOD

  • The surface should be strong, firm and free of dust, dirt, or other elements that may be separating elements such as paint, adhesive residues, lime ... any screed or existing substrate, not resistant to moisture, also it should be removed. Concrete curing agents, additives and surface hardeners, or residues of pampering should be affecting the adhesion, so it should be removed by shot-blasted, sanded, hot air or compressed.
  • Remove superficial water
  • The original packaging resin and hardener are pre-measured to exact quantities. The curing agent (component B) is added to the resin (component A) and stirred with spiral rod at low speed until a uniform consistency and colour. It is very important that the components of the resin are thoroughly mixed.
  • Apply at temperatures above 10°C
  • Apply the layer of PRIMER WET with a trowel. While PRIMER WET is still fresh, it should smoothing trowel marks a short nap roller, which should be wet before with the same product.
  • The application thickness should not be less than 350 microns. (aprox.600 g/m²). It is important that the application is continuous and free of pores or cavities; otherwise the application should be repeated.

HANDLING AND TRANSPORT

These safety recommendations for handling, are necessary for the implementation process as well as in the pre-and post, on exposure to the loading machinery.

  • Respiratory Protection: When handling or spraying use an air-purifying respirator.
  • Skin protection: Use rubber gloves, remove immediately after contamination. Wear clean body-covering. Wash thoroughly with soap and water after work and before eating, drinking or smoking.
  • Eye / Face: Wear safety goggles to prevent splashing and exposure to particles in air.
  • Waste: Waste generation should be avoided or minimized. Incinerate under controlled conditions in accordance with local laws and national regulations.

Anyway, consult the material and safety data sheet of the product(MSDS) or contact our technical department.
