The Complete Tarpaulin Buying Guide
2026 — UK Edition
Everything you need to choose the right tarp — materials, weights, sizes, colours, fixings and applications. Written by our specialist team.
1 What is a Tarpaulin?
A tarpaulin — commonly called a "tarp" — is a large, flexible, waterproof or water-resistant sheet used to protect surfaces, equipment, and structures from the elements. The word derives from "tar" (historically used to waterproof cloth) and "palling" (a covering). Modern tarps are manufactured from synthetic polymers, offering far superior performance to the original canvas versions.
Today, tarpaulins are used across every industry — from covering a garden woodpile to protecting military equipment on active operations. They are arguably the most versatile protective material ever made. Understanding the differences in type, weight, and material is essential to getting the right product at the right price.
Expert Tip
The single most common buying mistake is choosing a tarp that's too light for the application. Always buy one weight category heavier than you think you need — the price difference is small, the durability difference is substantial.
2 Tarpaulin Materials: PE vs PVC vs Canvas
The three core materials each have distinct strengths. Choosing the wrong one is the most expensive mistake buyers make.
Polyethylene (PE)
The most popular choice for domestic & light commercial use.
- Fully waterproof & UV-resistant
- Lightweight & easy to handle
- Available 70–270gsm
- Best value for most applications
- Less durable than PVC in extremes
PVC Tarpaulin
The premium industrial-grade choice. Significantly more durable.
- 10× stronger than equivalent PE
- Flexible to −30°C
- Welded seams — fully watertight
- Chemical & fire retardant options
- 5–12 year outdoor lifespan
Canvas Tarpaulin
Traditional material valued for breathability & aesthetics.
- Breathable — prevents condensation
- Biodegradable & sustainable
- Heavier than synthetic tarps
- Wax-treated for water resistance
- Classic country & heritage look
PE vs PVC — The Definitive Answer
For any application lasting more than 12 months outdoors, or involving heavy physical contact, choose PVC. For seasonal domestic use, a good quality PE tarp is sufficient and much more affordable. The cost difference between a 200gsm PE and an equivalent PVC is typically 3–5×, but PVC will last 3–4× longer.
3 Tarpaulin Weight Guide (GSM Explained)
GSM (grams per square metre) is the most important specification when choosing a tarpaulin. It tells you the density and durability of the material. Higher GSM = heavier and more durable, but also heavier to handle and more expensive.
| GSM Range | Grade | Typical Applications | Expected Life | Best For |
|---|---|---|---|---|
| 70–90gsm | Ultra Economy | One-off use, decorating sheets, emergency cover | 1 season | Short-term domestic |
| 100–120gsm | Economy | Garden furniture, camping groundsheet, light outdoor use | 1–2 seasons | Budget domestic |
| 140–160gsm | Standard ★ | Log stores, caravan covers, allotments, general outdoor | 2–4 years | Most domestic uses |
| 170–200gsm | Medium-Heavy | Construction sites, scaffolding, vehicle covers, agriculture | 3–5 years | Light commercial |
| 250–270gsm | Super Heavy | Industrial machinery, skip covers, permanent installations | 5+ years | Commercial/industrial |
| 500–900gsm | PVC Industrial | HGV curtains, permanent structures, lorry sheeting | 8–12+ years | Heavy industrial |
The Most Common Buying Mistake
Buyers consistently underestimate the weight they need. A 90gsm tarp left outdoors through a UK winter will fail at the eyelets within months. For anything left outdoors year-round, start at 140gsm minimum. For any commercial application, start at 200gsm.
4 Tarpaulin Size Guide
Choosing the right size is critical. Our golden rule: always go at least 50cm larger than the item on every side. For permanent outdoor use, add 1 metre per side for proper overhang, tie-down margin, and wind allowance.
Size Calculation Formula
Minimum size = Item length + 1m × Item width + 1m (+ item height × 2 for tall items). For irregular shapes, measure the widest points and add a full metre to each dimension. When in doubt, go bigger — a folded overhang is never a problem; a tarp that's too small is useless.
5 Tarpaulin Colours & Their Uses
Colour affects visibility, heat absorption, and application suitability. Here's our definitive colour guide:
6 Eyelets & Fixing Points Explained
Eyelets are the metal rings spaced around the tarpaulin perimeter. Their quality and spacing significantly affects the tarp's lifespan — most failures happen at fixing points, not in the body of the tarp itself.
- All quality tarpaulins should have double or triple-reinforced corner patches — the highest stress points
- Look for heat-sealed or welded eyelet surrounds on PVC tarps — stitched surrounds will eventually leak
- Never pull from a single eyelet — always distribute load across multiple fixing points
- Economy tarps with 10cm eyelet spacing are fine for lightweight, short-term use
- For permanent installations, specify every 50cm eyelet spacing minimum
7 How to Secure a Tarpaulin Properly
A poorly secured tarpaulin is both dangerous and destructive — wind loading on an improperly fixed tarp can generate enormous force. Follow these professional best practices:
- Use proper bungee hooks or rope through eyelets — never just drape and weigh down with objects
- Tie from alternate eyelets to distribute load evenly across the perimeter
- For roofing applications: Always create a ridge or peak to prevent water pooling — flat tarps will fail under water weight
- In exposed or windy conditions: Use minimum 3 anchor points per side and check daily
- For vehicle covers: Use bungee straps under the vehicle, not over the top, to prevent scratching
- For scaffolding: Tarps must be mechanically fixed with clips or ties, never rely on weight alone
Wind Loading — The Hidden Danger
A 6m × 4m tarpaulin exposed to 60mph winds generates approximately 1.4 tonnes of force. Inadequate fixing points will fail catastrophically. In any exposed location or forecast high winds, over-secure and regularly inspect your fixings. Never use cheap garden twine as the sole fixing method.
8 Flame-Retardant Tarpaulins: When Are They Required?
For many applications, standard tarpaulins are not permitted by law or health & safety regulations. Flame-retardant (FR) tarpaulins carry specific certification to show they meet fire performance standards.
| Application | Standard Required | Notes |
|---|---|---|
| Public events & festivals | BS 5438 / BS 7837 | Usually required by local authority licence condition |
| Scaffolding shrouds (occupied buildings) | LPS 1207 / BS 7157 | Mandatory for occupied premises |
| Theatre & stage | M2 or BS 5438 | Varies by venue and local authority |
| Schools & public buildings | BS 5438 | Any covering material within a public building |
| Near welding / hot work | FR rated minimum | Standard tarps will ignite from welding sparks |
| EU markets | DIN 4102 B1 / M2 | Required for cross-border commercial applications |
Always Request a Fire Certificate
Any reputable supplier of FR tarpaulins should be able to provide a test certificate showing which standard has been met and the test date. Certificates must not be more than 5 years old. Our FR range meets BS 5438, M2, and DIN 4102 B1 — certificates available on request.
