Castle-Seal "Dry-It-Out"

FAQ'S

DESCRIPTION AND USES

DRY-IT-OUT 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 DRY-IT-OUT 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 removing the damp and waterproofing, it also makes the surface resistant to staining and prevents algae growth. DRY-IT-OUT will also strengthen porous masonry such as sandstone and limestone reducing the likelihood of weather and frost damage. DRY-IT-OUT will also prevent the transmission of damp through the walls and floors of buildings. It can be used inside and out. DRY-IT-OUT will also protect softwoods from mould and rot.

 INSTRUCTIONS FOR USE

DRY-IT-OUT 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 DRY-IT-OUT is to be applied should ideally be clean 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 DRY-IT-OUT 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 DRY-IT-OUT are an effective waterproof barrier however DRY-IT-OUT may also be over painted with any conventional paint systems. It may also be plastered or rendered over with conventional screeding materials.

WARNING: DRY-IT-OUT 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.

NOTES FOR USAGE

DRY-IT-OUT as a masonry damp proofing: one coat normally sufficient.

DRY-IT-OUT as a reinforcement for friable stone: three or four coats required.

DRY-IT-OUT as protection against staining: one coat normally sufficient, two coats will produce a sheen.

IMPORTANT NOTE:

DRY-IT-OUT is only suitable for porous surfaces. Do not attempt to use it on surfaces, which have already been sealed with other products. Softwoods, which have been rot-proofed by pressure treatment or dipping, can normally be sealed with DRY-IT-OUT, however timber treated with certain proprietary wood preservers such as Cuprinol may not be suitable for sealing. A small test area will determine whether the product can soak in. If it does not penetrate, do not use.

 

This data is provided in good faith for guidance purposes however due to variations in equipment and local conditions. Users should carry out their own tests to ensure that satisfactory results can be obtained.
