California® Acrylic Resurfacer 920-29
ACRYLIC BASE FOR RECREATIONAL SURFACES
1.0 MATERIAL DESCRIPTION
Acrylic Resurfacer is a concentrated 100% acrylic latex binder designed for field mixing with silica sand and is to be applied to recreational surfaces constructed of hot-mix asphalt or Portland cement concrete.
2.0 INTENDED USE
Acrylic Resurfacer is intended for preparing new asphalt or concrete surfaces as well as existing acrylic surfaces for colour coating.

Note: Low temperatures or high humidity will increase drying time drastically. Maximum surface temperature = 140° F.
4.0 SURFACE PREPARATION
4.1 BASE CONSTRUCTION
Surface must meet or exceed the American Sports Builders Association (ASBA) applicable Guidelines. Upgrading and recoating previously colored surfaces requires the surface and base construction to be in sound condition and in compliance with the applicable ASBA Guidelines.
4.2 SUBSTRATE CURE REQUIREMENTS
New hot-mix asphalt surfaces must be allowed a minimum of 14 days cure time before application of Acrylic Resurfacer. For new, Portland cement concrete surfaces, a minimum of 28 days cure time is required. After 28 days, new concrete must be acid-etched with either phosphoric or muriatic acid. Application may begin thereafter.
4.3 SURFACE CONDITION
The surface on which DecoColor is to be applied must be smooth, free of dirt, loose or flaking paint, oily materials or chemical residues, vegetation of any sort and any other debris or foreign matter that may prevent the proper product adhesion. Thoroughly rout existing cracks of dirt, debris and loose impediments. Cracks should be blown clean with an air compressor. Consult the data sheet 64061 Deco Crack Filler for application information.
4.4 SURFACE IMPERFECTION
Before application of primers or Acrylic Resurfacer, the court surface shall be flooded with water and allowed to drain. Any depressions capable of submerging a U.S. five-cent piece after one hour should be marked with chalk, not crayon or a grease pencil. These areas must be allowed to thoroughly dry. Once dried, a patch must be applied to the marked area. For patching products and mix designs, please refer to the product data sheet for Court Patch Binder 920-39.
Priming of asphalt surfaces is only necessary if existing asphalt is too badly weathered to establish a strong bond with the Acrylic Resurfacer. In the case of extremely oxidized asphalt surfaces, contact your Deco Area Manager. When applying Acrylic Resurfacer to new concrete surfaces, a primer is necessary to improve adhesion. Deco Surfacing Systems offers California Ti-Coat, a two-package water based epoxy primer. Consult the respective data sheets for proper application. If the concrete surface has been previously coated with acrylic material, no priming is necessary.
5.0 MIXING INSTRUCTIONS
The following mixes have been found to be satisfactory for average surface conditions:
Acrylic Resurfacer 55 gallons - 30 gallons
Silica Sand (60 - 80 Mesh) 600-900 lb. 325-400 lb.
Clean potable water 20-40 gallons. 11 – 22 gallons
5.1 SAND MIX
Do not use sand containing clay, silt, ferrous metals or salt. The outcome of the Resurfacer mix depends heavily on what type of sand you chose. Our specifications are based on 60-80 mesh sand. The addition of the silica sand should be done slowly, under agitation.
5.2 WATER MIX
In no case should Acrylic Resurfacer be diluted more than three (3) parts Acrylic Resurfacer to two (2) parts water. The quantity of water required will vary with moisture content and gradation of the sand and the consistency needed for good application characteristics.
5.3 RESURFACE MIX
After the addition of sand and water to the Acrylic Resurfacer concentrate, thorough mixing is required. A mechanical drill mixer is recommended and mixture should be stirred until homogeneous. Periodic mixing should take place as the job progresses to ensure consistent application.
6.0 GUIDE TO APPLICATION
6.1 SYSTEM RECOMMENDATION
Deco recommends one 1-2 coats of Acrylic Resurfacer prior to the application of any Deco Surfacing System. If using the Street Ice system, a minimum of two (2) coats is recommended. See Street Ice S/I-3 for further information.
Using a flexible rubber squeegee, apply Acrylic Resurfacer mix parallel to one of the sides of the surface area. Care should be taken not to leave ridges where adjoining applications overlap. Under hot conditions, application is improved by keeping surface damp with a fine mist water spray. Never allow water to pool on the surface.
6.3 DRYING AND CURE TIME
Acrylic Resurfacer must be allowed to cure a minimum of 2 hours before applying acrylic coatings.
The undiluted coverage rate is approximately 0.06 gallons per square yard, per application.
All equipment can be cleaned with water if clean-up occurs immediately after application.
9.1 SURFACE LIMITATIONS
Acrylic Resurfacer is limited to application on hot-mix asphalt and Portland cement concrete recreational surfaces. Deco Surfacing Systems does not recommend, nor authorize the application of Acrylic Resurfacer on any other surfaces without prior approval from your Deco Area Manager.
9.2 WEATHER LIMITATIONS
No part of the construction involving the Deco Surfacing System should be conducted during rainfall, or when rainfall is imminent. The air temperature must be at least 60ºF and rising. Do not apply when surface temperature is above 140ºF.
9.3 DO NOT OVER DILUTE
The maximum dilution ratio is 3:2. Over dilution will cause streaking, foaming, adhesion failure, sand fall-out and poor overall durability of the coating.
9.4 INDOOR APPLICATION DRYING
Drying times are retarded by high humidity, cool temperatures or lack of air movement. This is particularly important to note when installing indoors, where all three factors are often very pronounced.
