Nitoflor PAFS Topcoat

Standards Compliance

Preparation

New concrete surfaces

Surfaces should be clean, dry and free of laitance, oil, grease. The concrete should have a moisture content of <75% RH.

Existing concrete surfaces

Should be structurally sound, concrete repairs carried out using Fosroc repair products; refer to your local Fosroc office for more details. Surfaces should be clean, dry, and free of laitance, oil and grease. The concrete should have a moisture content of <75% RH.

Steel surfaces

Must be of first-class quality and must not have been allowed to rust more than corresponding to grade B of ISO 8501- 1: Any laminations must be removed. Blast cleaning to SA 2½. (ISO 8501-1:2007). Roughness: using abrasives suitable to achieve a coarse surface of Grade Medium G (50-85μm, Ry5) (ISO 8503-2). For other substrates please contact the Fosroc or Rawlins Technical Department on 0113 2455450 (option 2) or send a message to [email protected].

Treatment of cracks / joints / day-joints / up -stands

Consult Fosroc or Rawlins Technical for details of treatment.

Application Temperature

Normal application temperature range is 5-30°C.

For application temperatures below 5°C or above 30°C, contact the Fosroc or Rawlins Technical Department on 0113 2455450 (option 2) or send a message to [email protected].

Nitoflor PAFS Topcoat must be applied only to the cured primer, evenly and without leaving puddles by means of a squeegee, paint roller or brush. If rubber blades are used, the surface must always be rolled with a paint roller afterwards. Allow Nitoflor PAFS Topcoat to properly cure before opening to traffic.

Pre-Application Check

Before starting works, the user should check:

Moisture content of concrete is <75% RH, Patch-apply Nitoflor PAFS Primer to ensure no inhibition of cure or bond from substrate contaminants. Mode of failure is either cohesive substrate or coating-to-substrate >1.5N/mm²

Mixing

Nitoflor PAFS Primer 1: Add the contents of the Hardener can to the Base can, ensuring the sides are scraped clean. Using a slow speed drill and paddle, mix for 3-4 minutes, stopping halfway to scrape the sides and bottom of the can.

Nitoflor PAFS Topcoat Once the Primer coat has cured, follow the same mixing procedure for the Topcoat. If the Topcoat is supplied as a pre-pigmented base, gently stir the Base component before mixing to ensure no settlement. If the Topcoat has a third component colour pack, ensure its container is scraped clean into the Base can and fully dispersed before adding the Hardener.

Application

Nitoflor PAFS Primer must be applied first, evenly and without leaving puddles, by means of a squeegee and back rolled. If rubber blades are used, the surface must always be rolled with a paint roller afterwards. Heavily absorbent patches must be re-primed wet-into-wet before hardening until the pores are closed.

Nitoflor PAFS Primer must be allowed to properly cure before over-coating.

Cleaning

Tools and equipment can be cleaned immediately after use with Fosroc Equipment Cleaner.

Yield / Estimating

One pack of Nitoflor PAFS Primer, applied at 0.5kg/m², will cover approximately 10m².

One pack of Nitoflor PAFS Topcoat, applied at 0.4kg/m², will cover approximately 12m².

Limitations

Nitoflor PAFS (System 1) products should not be applied below 5°C or above 30°C. For advice on other application temperatures please contact Fosroc or Rawlins Technical Department on 0113 2455450 (option 2) or send a message to [email protected].

Do not apply to wet or damp surfaces as the bond strength will be reduced. Protect from rain until cured. If in any doubt concerning substrate condition or application temperature consult your local Fosroc office, or Rawlins Technical.
