By Bunnings magazine /

Overview

Your hard-working garage deserves to look its best. Dy-Mark Epoxy Coat, a D.I.Y. garage floor coating kit, will make your garage look showroom-chic. All you need is a couple of weekends and you’ll have a fresh garage floor.

This handy guide is an overview of the process and will help you get started. For complete instructions, and to ensure a durable and long-lasting finish, read and follow the product instruction manual.

Safety tip: Always wear the appropriate safety equipment (safety glasses, gloves, and a mask, for example) and always follow the instructions for the product or equipment.

Steps

  1. 1

    Preparation

    Start with a clean, unpainted concrete floor that is swept, scrubbed and stain-free.

    Etching

    Etch the floor. This involves using a diluted acid etch to roughen the surface of the concrete and maximise the adhesion between the surface and the epoxy product. Put on your safety equipment, wet the floor and spread the diluted etch. Work it in with a stiff broom. When the solution has stopped fizzing, rinse thoroughly and remove excess water with a rubber squeegee. Let it dry for at least three days. Do a moisture test before moving on to step #3.

    Repair holes

    Use a filler product to repair any holes or cracks, removing any dust when you’re done. Finish your prep by taping up the trims, skirtings or walls where they meet the floor.

    Mix the epoxy

    Mix the epoxy by stirring together the two parts. Mix with a flat paddle stirrer for three to five minutes. Leave the mixture for the appropriate induction time and then apply it within the pot life of the product (see full instructions).

    Cut in the edges

    Use a brush to cut in the edges and then use a roller to apply the epoxy. Work in sections of one square metre, scattering decorative flakes over the wet sections as they’re laid. For the best result, your new epoxy floor should cure for seven to 10 days before restarting heavy vehicle or foot traffic. 

    Tip: Choose the right option for your garage: solvent-based kits will give a glossy finish to your floor, while water-based kits provide a chic satin finish.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
