Castleseal-2 is a clear, solvent based epoxy sealer, which is used on porous substrates to remove moisture and provide a waterproof surface. The hydrophilic properties of Castleseal-2 enable it to locate and displace water from the pores of the substrate where it then cures to form a permanently sealed surface layer. As well as waterproofing it also makes the surface resistant to staining and prevents moss and algae growth. Castleseal-2 will also strengthen porous masonry such as sandstone and limestone reducing the likelihood of weather and frost damage. Castleseal-2 (see also "Dry-it-Out") will also prevent the transmission of damp through the walls and floors of buildings. It can be used inside and out. Castleseal-2 will also protect softwoods from mould and rot.

+ = Resistant 0 = Not resistant. All chemical resistance is measured at 21ºC

Castleseal-2 can be applied by low pressure spray, roller or brush. One coat will normally be sufficient to seal most porous surfaces and leave the surface virtually unchanged in appearance. Second and subsequent coats will leave a slight surface sheen. All surfaces to which Castleseal-2 is to be applied should ideally be clean, dry and free from dust and loose particles. Acceptable penetration and adhesion can be achieved on damp surfaces (remove surface water first). Mix two parts of Castleseal-2 Base with one part of Hardener and stir well for 2/3 minutes. (7.5 litre packs are pre-measured). Mixed material will remain usable for 24 hours if the container is kept sealed.

Application with a low pressure sprayer is most economical but rollers and brushes are equally effective (if spraying, use a sprayer suitable for solvents otherwise the internal seals may be affected by solvent). The Castleseal ''Sure Shot'' sprayer is recommended.

After application, allow the first coat to soak in. Water droplets may appear on the surface as the product penetrates and drives out the moisture. Allow the first coat to cure for at least 2 hours before overcoating.

One or two coats of Castleseal-2 are an effective waterproof barrier however Castleseal-2 may also be over painted with any conventional paint systems. It may also be plastered or rendered over with conventional screeding materials.

WARNING: Castleseal-2 contains volatile, highly flammable solvents. It must only be applied outside or in a well-ventilated area otherwise breathing apparatus and extraction equipment will be required. Observe Health and Safety information on labels.

Clean equipment with acetone or M.E.K. before the material cures.

Wet film thickness 50 microns

Dry film thickness 17 microns

Coverage 15-18 m²/litre (1 coat)

Castleseal-2 as a primer: one coat normally sufficient.

Castleseal-2 as a masonry damp proofing: one coat normally sufficient (see also "Dry-it-Out").

Castleseal-2 as a reinforcement for friable stone: three or four coats required.

Castleseal-2 as protection against oil staining on drives, etc.: one coat normally sufficient, two coats will produce a sheen and on block paving two coats will help to prevent sand loss from the joints reducing subsidence risks.
