3. Product Description

BASIC USE & COMPOSITION
TEX•COTE^® XL-70^® Concrete/Masonry Protective Coating is a high-build, plasticized, vinyl toluene acrylic resin system specially formulated to provide a weatherproof coating over cured or uncured concrete masonry surfaces. The ability to go over damp or high alkaline surfaces is a key feature. This coating is recommended for use over all types of concrete, cement plaster, block, brick and other manufacturer approved surfaces.

PACKAGING & COVERAGE
Container sizes - 5, 30 and 55 gal (19, 113 and 209 L). Material coverage rates vary due to surface porosity, texture and application method.

COLORS
Product is available in TEX•COTE^® standard colors. Contact the manufacturer for special color matching which is available for most colors.

FINISHES

• Roller Applied - Smooth, fine texture
• Spray Applied - Smooth, fine, coarse, extra coarse textures

LIMITATIONS
TEX•COTE^® Textured Coatings are for use in above grade applications only.

Joint sealants used must be compatible with selected TEX•COTE^® products. Contact the manufacturer to confirm compatibility.

5. Installation

PREPARATORY WORK
All surfaces must be sound and clean. Surface contaminants such as dust, dirt, mildew, form oils and laitance must be thoroughly removed. Painted surfaces exhibiting loose, flaking, or oxidized paint surfaces must be thoroughly removed by sand blasting, water blasting, electric sanding, or wire brushing as required by the manufacturer. All surfaces must be primed prior to coating substrates.

TEX•COTE^® XL-70^® can be applied over damp, uncured concrete, masonry surfaces. TEX•COTE^® XL-70^® can be applied without a primer on approved concrete surfaces.

Large cracks, holes or voids must be filled with cement patching compound with Tex-Bond Cement Adhesive. Patching compound finish texture to match existing adjacent finish surfaces. Cracks over 1/16" (1.6 mm) and less than 1/8" (3.2 ram)should be filled with FlexPatch Patching Compound. Interfacing of wall joints must be sealed with a urethane type sealant.

Metals
A detailed technical data sheet on surface preparation, degreasing, and etching is available for all applications on metal surfaces. Consult a local TEX•COTE^® representative prior to commencing application on metals.

A sample wall is recommended for field approval by the architect, manufacturer's representative, and contractor.

APPLICATION PRECAUTIONS
Apply TEX•COTE^® XL-70^® only under the following conditions:

• Roof and parapet top caps are installed and sealed against water penetration
• Primer exposed to ultraviolet rays for more than four weeks requires repriming
• Joint sealants have cured minimum 48 hours
• Retaining walls, planter boxes and similar construction are waterproofed on the soil side
• Rain is not imminent and surfaces are not damp or frozen; avoid freezing product
• Surface and ambient air temperature range is 40°F - 100°F (5°C - 38°C]

This product, when still in liquid form, contains petroleum distillate which will cause serious illness or death if swallowed or if large quantities are absorbed into body. Use in well ventilated areas. Use approved respirator in poorly ventilated areas. Keep liquid product away from heat sources and children. If swallowed, do not induce vomiting. Seek medical treatment immediately.

ROLL ON APPLICATION METHODS
Short, medium, or long nap rollers can be used for standard applications, depending on texture desired.

With fully loaded roller, apply first coat at approximately
90 - 100 sf/gal (2.2 - 2.5 m²/L).
Allow 24 hour curing. Apply second coat at approximately
90 - 100 sf/gal (2.2 - 2.5 m²/L) to achieve a pinhole free, continuous film. When rolling, apply first with vertical strokes, then cross roll for even film and desired appearance.

SPRAYED ON APPLICATION METHODS
Provide spray equipment similar to Graco President, 10:1 pump or Graco GM 1030 and Graco 204-000 Spray Gun. A TEX•COTE^® spray application manual is available upon request.

Installer must comply with the following:

• Application of TEX•COTE^® must be at uniform pinhole free continuous film thickness over the entire surface.
• Maintain a wet edge at all times to prevent lap marks. Avoid starting and stopping midway on the wall surface. Continue spraying to a natural break point such as a panel edge, seam or corner.
• For large surface areas, two people spraying simultaneously are recommended to avoid lap marks and spray patterns. To achieve a proper surface, request the assistance of the manufacturer's representative.
• Apply coating at a rate of 30-50 sf/gal (.7 - 1.25 m²/L) depending upon the porosity of the substrate and finish texture desired. A minimum of 15-17 mils (.38 - .43 mm) dry film thickness is required. Consult the manufacturer for standard textures and specific coverage rates for texture to be used and samples.

CLEAN UP
Use mineral spirits for cleaning wet material. Use Methyl Ethyl Ketone (MEK) to remove dry material. Attempt sample in concealed area first.

SHELF LIFE

• 12 month shelf life under proper conditions
• Containers must be stored upright and airtight in a dry place.
• Maintain air temperature of 45°F - 100°F (7°C - 38°C)
• Skins formed on surface of material must be removed prior to moving containers or mixing.
