STAN PROTECT
Tannin blocker
 Coverage: 10-12 m²/l |
 Application temperature: +5°C to +35°C |
 Dry: 2 h - Recoat: 6 h |
PROPERTIES
STAN PROTECT is a clear, penetrating tannin blocker that prevents the bleeding and leaching of tannins from woods’ high in extractives and also the discolouration of finishes on interior softwoods. Forming a barrier within the wood, STAN PROTECT blocks the tannins, preventing them from reaching the surface where they will discolour a finish or stain.
Functions
- Prevents discoloration of finishes caused by tannin bleed/staining.
- Improves penetration and opacity of finishes.
- Blocks tannin bleed/leaching - Improves adhesion of the finish
- Colourless – Does not hide the wood grain.
- Easy Application. Quick drying.
- Extends the life of a finish – Prevents premature aesthetic and physical degradation of the finish.
- Limits yellowing or browning of light coloured interior softwoods – Pine, Spruce, Larch…
- Overcoat with any film forming oil or water based stain (Semi-transparent or Opaque).
WHERE TO USE
- Exterior and Interior.
- Vertical and Horizontal surfaces.
- New or old uncoated wood.
- Use before application of opaque or semi-transparent stains.
- Recommended for woods high in tannin - Cedar, American Redwood, Oak, Chestnut…
- Shingles, Cladding, Chalets, Skirting boards, Doors…
SURFACE PREPARATION
General Directions:
- Surfaces must be clean, dry and free of dirt, grease, grime, mildew and previous coatings.
- Treat mildew with a 50/50 bleach/water solution. Scrub solution on to surface and allow to stand for 10 to 15 minutes; rinse thoroughly.
- After cleaning and/or stripping, allow wood to dry 2 to 3 good drying days or until it has reached a moisture content of 18 % or less before applying STAN PROTECT.
- STAN PROTECT can only be applied to bare wood surfaces. ALL other finishes MUST be completely and thoroughly removed.
- If necessary sand surface after cleaning and/or stripping (80 grit or coarser depending on wood species).
New wood surfaces:
- Test wood for absorbency by sprinkling water on the surface. If water is absorbed quickly, the grain is sufficiently “open” and the surface is ready for finishing, proceed to “Application”. If water is not absorbed then proceed as follows:-
- Treat wood with AQUANETT or PREPDECK, neutralise with NET-TROL, alternatively mechanically or manually abrade surface with 80 grit paper or coarser depending on wood species.
- Clean and dust off to remove all loose wood particles.
Weathered wood surfaces (untreated):
- Wood that has weathered longer than 12 months or turned grey should be cleaned with NET-TROL to remove all loose wood fibres, dirt and other surface contaminants. If wood is severely contaminated, clean with AQUANETT or PREPDECK and neutralise with NET-TROL.
Previously treated surfaces (oiled, paint, stain, varnish….):
- All previous finishes must be completely and thoroughly removed.
- Oils and sealers: Strip with AQUANETT or PREPDECK, neutralise with NET-TROL.
- Solvent (oil or alkyd based finishes): Strip with DILUNETT, neutralise with NET-TROL.
- Acrylic finishes (Water-based): Strip with PREPDECK, neutralise with NET-TROL.
- Other finishes e.g. 2 pack epoxies, urethanes...: Strip with DSP 800, neutralise surface with a suitable solvent – Acetone, White Spirits, Methylated Spirits….
Note: Hardwoods inc. exotic hardwoods and woods rich in tannins i.e. Cedar, Douglas Fir, Teak, Ipe, Iroko…. may darken with AQUANETT, PREPDECK, and DILUNETT, neutralising with NET-TROL immediately after rinsing will lighten and restore the woods colour.
Application
- Use as is. Do not dilute.
- Shake or stir can well before use.
- All Woods – New, Cleaned or Stripped.
- Brush, Roller, Spray
- Apply one liberal, even, saturating application to all wood surfaces.
- Soak in to end grain including any cut, bored or notched ends.
- Allow to dry.
- Dipping: Soak wood for 10 minutes.
- Drain off excess STAN PROTECT.
- Allow to dry.
Note: If the over coating of STAN PROTECT exceeds 48 hours, lightly sand surface with 80 grit paper and thoroughly dust off before applying the finish.
Recommendations after Application
- Clean all tools and equipment with diluted SOAPCLEAN or soap and water immediately after use.
